Description

Electric applicator and method for reattaching an artificial eyelash extension and curling natural eyelashes and artificial eyelash extensions attached to natural eyelashes

Technical Field

Embodiments of the present disclosure relate generally to applicators for natural and artificial eyelash extensions, and more particularly, to an electrical applicator for reattaching and curling natural and/or artificial eyelash extensions attached to natural eyelashes.

Background

False eyelash extensions are commonly used to enhance the length, thickness, and fullness of natural lashes.

Some false lashes may be applied directly to an individual's eyelid. False eyelashes can appear in the form of a strip

(And thus may also be referred to as "striped eyelashes") that may be trimmed to fit the width of an individual's eyelid.

Detailed Description

As described above, eyelash extensions have been used to enhance the length, thickness, and fullness of natural eyelashes. The striped eyelashes applied to the user's eyelid are easily distinguished from the user's natural eyelashes and may be unsuitable if worn for a long period of time. Some eyelash extensions are applied to an individual's natural eyelash hair by hair-by-hair or, in some cases, cluster-by-cluster. Due to the precise nature of applying individual hairs or clusters, a skilled person may perform the application of said individual hairs or clusters. Such services may cost hundreds of dollars and take up to several hours to complete.

In some cases, an individual may wish to curl their natural eyelashes and/or an extension of eyelashes that has been applied to the individual's natural eyelashes. Because of the unique geometry and sensitivity of the eye region, existing tools may not use heat to curl the natural eyelashes and/or artificial eyelash extensions, or have shapes or other features that are not suitable for curling the natural eyelashes and/or eyelash extensions.

In other cases, an eyelash extension worn by an individual may fall out or otherwise reduce adhesion to the individual's natural eyelashes. An individual may wish to improve the bond quality and increase the amount of time an individual may wear an eyelash extension.

To address the above and other challenges, disclosed herein is an electrical applicator designed to curl one or more natural lashes or artificial lash extensions attached to natural lashes. The electrical applicator provides a new and improved way to curl eyelashes, artificial eyelash extensions, or both with much more control than conventional solutions. The electrical applicator may also be used to reattach an artificial eyelash extension that has been previously attached to the natural eyelash (e.g., a few days ago), thereby improving the bond between the natural eyelash and the artificial eyelash extension, and extending the bond between the natural eyelash and the artificial eyelash extension over time.

In some embodiments, the electrical applicator includes a handle and a pair of opposing arms coupled to the handle. Each arm includes a portion having a first bend between a first end and a second end of the portion. The first curved portion is shaped to align near the line of lashes of the eye region. The electrical applicator includes a heating unit configured to heat the portion (e.g., both the inner and outer surfaces of the portion) of each arm.

In some embodiments, the electrical applicator includes a cooling unit to cool the portion of each arm.

In some embodiments, at least a portion of the inner surface corresponding to the first portion of each arm includes a surface that is substantially planar and is designed to apply pressure to the natural eyelashes and one or more artificial eyelash extensions attached to the natural eyelashes (e.g., an underside thereof). In some embodiments, at least a portion of the outer surface corresponding to the first portion includes a curved portion having a surface with a curvature positioned between the first and second sides of each arm. The curvature of the first portion (along with the heat) is designed to curl one or more natural lashes or one or more artificial lash extensions attached to the natural lashes.

In an illustrative embodiment of curling natural eyelashes and artificial eyelashes extensions, the electrical applicator may be heated to a desired temperature. The heated electrical applicator may be closed over the natural eyelashes and the artificial eyelash extension attached thereto such that the heated inner surfaces of the arms of the heated electrical applicator contact and apply pressure to the natural eyelashes and the artificial eyelash extension therebetween. The heated electrical applicator may rotate about an axis of rotation and the natural eyelashes and/or artificial eyelash extension may contact the heated outer surface (which may also be curved) of the portion of the at least one arm. Contact between the natural and/or artificial eyelash extensions and the inner and outer surfaces of the arms of the heated electrical applicator can be maintained for a period of time to fix the curl of the natural and/or artificial eyelash extensions.

In another exemplary embodiment, the electrical applicator may be heated to a desired temperature in order to reattach the artificial eyelash extension attached to the natural eyelash using an adhesive. The original attachment of the artificial eyelash extension may have occurred some period of time before, such as days before reattachment. The heated electrical applicator may be closed over the natural eyelashes and the artificial eyelash extension attached thereto such that the heated inner surfaces of the arms of the heated electrical applicator contact and apply pressure to the natural eyelashes and the artificial eyelash extension therebetween. The originally applied adhesive may begin to soften and redistribute between the natural eyelashes and the adjacent artificial eyelash extensions. After a period of time, the heated electrical applicator may be removed and the cooling unit of the electrical applicator activated. The pair of opposed arms can be cooled to a desired temperature and closed over the natural eyelashes, the artificial eyelash extension, and the redistributed adhesive. The redistributed adhesive may harden and reform and improve the bond between the natural eyelashes and the artificial eyelash extension such that the period of time the artificial eyelash extension is wearable is prolonged.

Fig. 1 is a diagram of an eye region according to some embodiments of the present disclosure. As shown in fig. 1, an eye region 100 (such as a human eye region) may include an upper natural eyelash 102A (also referred to herein as "natural eyelash 102A", or "natural eyelash 102A") and a lower natural eyelash 102B (also referred to herein as "natural eyelash 102B", or "natural eyelash 102B"). The natural lashes 102A and 102B may have an underside and a topside opposite the underside. For example, natural eyelashes 102A show underside 108. The natural eyelashes 102B show the top side 110. The natural lashes 102A and 102B are collectively referred to herein as natural lashes 102.

Eye region 100 includes upper mascara line 104 (also referred to herein as "ciliary line 104") and upper water line 106 (also referred to herein as "water line 106"). In some embodiments, a ciliary wire (such as the upper ciliary wire 104 or the lower ciliary wire of the natural eyelashes 102B) may include an area between the natural eyelashes. In some embodiments, the ciliary wire may be curved and follow the arrangement of natural eyelashes 102. In some embodiments, the upper wire 104 may include some skin area above (e.g., directly above) the natural eyelashes 102A and/or below (e.g., directly below) the natural eyelashes 102A. Similarly, the lower ciliary wire may include some area of skin below (e.g., directly below) and/or above (e.g., directly above) natural eyelashes 102B.

In some embodiments, waterlines (also referred to herein as "wet lines"), such as upper waterline 106 corresponding to natural eyelashes 102A and lower waterline corresponding to natural eyelashes 102B, may include skin areas (or lines) exposed between natural eyelashes 102 and the eyes.

Spatially relative terms, such as "below," "upper," "lower," "top," "bottom," and the like, as used herein, refer to the relative position of one element with respect to another element. Unless otherwise indicated, spatially relative terms are not intended to be limited to an absolute orientation and are intended to encompass different orientations of the elements in addition to the orientation depicted in the figures (e.g., rotated 90 degrees, flipped, etc.). For example, if an element in the figures is rotated 180 degrees, then the element described as an "upper" element may be considered to be oriented as a "lower" element without departing from aspects of the present disclosure.

Fig. 2 is an illustration of an exemplary artificial eyelash extension, according to some embodiments of the present disclosure. Fig. 3 is an illustration of another example artificial eyelash extension, according to some embodiments of the present disclosure.

In some embodiments, one or more of the artificial lash extension 200 or the artificial lash extension 300 (also referred to herein as "lash extension" or "artificial lash extension") is designed or configured for application at the natural lash, such as at the underside of the user's natural lash or even at the top side of the user's natural lash. In some embodiments, one or more of the artificial eyelash extension 200 or the artificial eyelash extension 300 may be part of a set of multiple artificial eyelash extensions. In some embodiments, one or more of the artificial lash extensions 200 or 300 may be a section of a "full" artificial lash extension such that, for example, when multiple artificial lash extensions are disposed adjacent to one another at the underside of a natural lash (e.g., natural lash 102A), the disposed artificial lash extension spans the length of the natural lash. In some embodiments, the artificial lash extension (e.g., segment) may be shorter than the horizontal length of the natural lash (e.g., length of the lash line). In other embodiments, the artificial eyelash extension may be longer such that the artificial eyelash extension is a "full" artificial eyelash extension that spans approximately the horizontal length of the natural eyelashes. The artificial eyelash extension may be arranged to be generally aligned with the user's line of lashes. In some embodiments, using the artificial eyelash extension as a separate segment can allow the individual artificial eyelash extension to move independently when adhered to the underside of the natural eyelashes, which mimics the movement of the natural eyelashes and may improve the feel, comfort, and longevity of the artificial eyelash extension.

The artificial eyelash extension 200 and the artificial eyelash extension 300 depict artificial hairs 202A-202N (collectively referred to herein as "artificial hairs 202") and artificial hairs 302A-302N (collectively referred to herein as "artificial hairs 302"), respectively. In some embodiments, artificial hair of an artificial eyelash extension, such as artificial eyelash extension 200 or artificial eyelash extension 300, may be formed from one or more synthetic materials, including but not limited to polybutylene terephthalate (PBT), acrylic, polyester (e.g., polyethylene terephthalate (PET)), other polymers, other synthetic materials, or combinations thereof. In alternative embodiments, natural materials may be used, such as natural hair (e.g., human hair or mink hair). In some embodiments, the artificial hair of a particular artificial eyelash extension may have one or more lengths and/or one or more diameters. In some embodiments, the artificial hair may have a diameter of between about 0.0075 millimeters (mm) (e.g., 0.0075mm +/-0.0025 mm) to 0.3mm (e.g., 0.3mm +/-0.05 mm). In some embodiments, the ends of one or more artificial hairs may be tapered. In some embodiments, one or more artificial hair may be curled or shaped in a particular direction. For example, the end 208 of the artificial hair 202 or the end 308 of the artificial hair 302 may be tapered or curled or both. In some embodiments, the length of the artificial hair may be in the range of 3mm to 30mm, or in some cases even longer.

In some embodiments, the artificial eyelash extension may include a base. For example, the artificial eyelash extension 200 includes a base 206. In some embodiments, the artificial lash extension 300 may or may not include (as shown) a base similar to the base 206 of the artificial lash extension 200. The base may include a top side (e.g., facing out of the page and toward the reader), a bottom side, a back side, a front side, and two lateral sides. In some embodiments, one or more of the plurality of artificial hairs of the artificial eyelash extension protrude from the front side of the base. When disposed at the underside of the natural eyelashes, the rear side of the artificial eyelash extension may be directed toward the user's eyes. The thickness (e.g., between the top and bottom sides of the base) may be between about 0.05 millimeters (mm) and about 0.15mm (e.g., 0.05mm +/-0.01 mm). In some embodiments, the thickness of the base may be less than 0.05mm. In some embodiments, the low profile of the base is designed to allow the artificial eyelash extension to be lightweight to better adhere to the underside of the natural eyelashes and, in some cases, to prevent obstruction of the user's field of view. The low profile of the base may be due, at least in part, to the application of heat in the formation of the base.

In some embodiments, one or more of the top or bottom sides (e.g., surfaces) of the base are substantially planar (e.g., have a flatness control tolerance value of +/-0.03mm or +/-0.015 mm). In some embodiments, the flatness of the base of the artificial eyelash extension 200 is designed to allow improved contact and attachment with a surface (such as the underside of a natural eyelash or the opposing surface of another artificial eyelash extension). The flatness of the base may be due, at least in part, to the application of heat in the formation of the base.

In some embodiments, the base may be formed at least in part by applying heat at or near an area of the base. The application of heat may cause one or more artificial hairs (e.g., all artificial hairs or clusters) of the artificial eyelash extension to be connected to or at the base. In some embodiments, a heated fixture, such as a heated platen, heated crimper, heat lamp, oven, or other device (e.g., pressing against an artificial hair) may be used to at least soften, tack, or stick (e.g., at least partially melt) the artificial hair (e.g., one or more artificial hair clusters). In some embodiments, the at least partially melted artificial hair (e.g., one or more clusters) forms at least a portion of the base. In some embodiments, the application of heat at least partially melts the artificial hair such that the plurality of artificial hair is connected to or at the base of the artificial eyelash extension. In some embodiments, the application of heat at least partially melts the artificial hair such that at least some of the plurality of artificial hair are connected to each other at the base of the artificial eyelash extension.

In some embodiments, to at least partially melt the artificial hair (e.g., and/or clusters of artificial hair) at the base, the artificial hair may be heated to a temperature between 55 and 100 degrees celsius, which may connect the artificial hair to the base or to each other at the base and/or in some cases. In some embodiments, the application heat temperature is above, within, or at the glass transition temperature of the material of the artificial hair. At the glass transition temperature, the material of the artificial hair changes from a frangible to a softer, rubbery, tacky or pliable state. In some embodiments, the application heat temperature is above, within, or at the melting temperature of the material of the artificial hair. For example, the base region (and/or other portions of the artificial eyelash extension) may be heated to above 200 degrees celsius.

In some embodiments, one or more additional artificial materials, such as one or more artificial hairs or other materials, may be placed substantially orthogonal to the artificial hair (e.g., aligned substantially horizontally with respect to a longitudinal direction of the artificial hair). In some embodiments, additional artificial material may be attached to the artificial hair. In some embodiments, the additional synthetic material may be considered a base or at least an initial base. In some embodiments, additional man-made material may be considered at least part of the base to be formed. In some embodiments, heat may be applied to the region where the base is to be formed (which may include additional artificial material). In some embodiments, one or more of the artificial hair and/or additional artificial material may be at least partially melted to at least partially form the base. In some embodiments, the additional artificial material may comprise an adhesive (e.g., application of adhesive) used alone or in combination with one or more other artificial materials (e.g., horizontal artificial hair, nylon, etc.). In some embodiments, the application of heat may be used to help cure the applied adhesive. In some embodiments using an adhesive, the application of heat may or may not partially melt the artificial hair.

In some embodiments, the base may be formed at least in part by applying pressure. In some embodiments, the base may be formed by applying pressure in combination with applying heat. For example, the application of pressure along with the application of heat may be applied simultaneously at the base of the artificial eyelash extension to at least partially melt and join together (e.g., fix together) and/or to (e.g., fix to) additional artificial material at least some artificial hair (e.g., some artificial hair of a cluster).

In some embodiments, the artificial hair may be tied (e.g., knotted) to a support or base wire or fiber to align the artificial hair and prevent horizontal spreading of the artificial hair prior to application of heat. The heat may be applied as described above (while tying the artificial hair to the support wire) such that the support wire forms a portion of the base. In other cases, heat may be applied below the horizontal support line. For example, the support wire may hold the artificial hair in place, and the application of heat may form a base below the support wire. In other embodiments, the artificial hair is not aligned with (e.g., knotted to) the support line before or during use of the application heat to form the base.

In other embodiments, templates or other placement devices may be used to place the artificial hair prior to and/or during use of the application heat to form the base. In some embodiments, one or more applications of heat may be performed to form the base. In alternative embodiments, the base may be formed in part or in whole using a chemical process.

In some embodiments, one or more of the artificial lash extension 200 and the artificial lash extension 300 include artificial hairs 202 and 302, the artificial hairs 202 and 302 being configured as artificial hair clusters 204A-204G (collectively referred to herein as "clusters 204") and artificial hair clusters 304A-304G (collectively referred to herein as "clusters 304"), respectively. In some embodiments, an artificial hair cluster may refer to two or more artificial hairs grouped together. In some embodiments, two or more artificial hairs of a cluster may be in contact with each other before and/or after the application of heat. In some embodiments, 2-30 artificial hairs may be included in a cluster.

In some embodiments, the artificial hair clusters can be attached to or at the base by application of heat in a similar manner as described above. In some embodiments, the application of heat at least partially melts at least some of the artificial hair in the one or more clusters of artificial eyelash extensions. In some embodiments, the application of heat may at least partially melt at least some of the artificial hair of at least one cluster such that at least some of the artificial hair of the cluster are connected to each other. In some embodiments, the application of heat may at least partially melt at least some of the artificial hair of at least one tuft such that at least some of the artificial hair of the tuft is connected to (and/or at least partially forms) the base of the artificial eyelash extension. In some embodiments, at least some artificial hairs of at least one cluster are connected to each other at respective portions of the base by at least applying heat.

In some embodiments, the clusters are connected to each other at the base by application of heat. In some embodiments, one or more clusters of artificial lash extensions are directly connected to at least one adjacent cluster at the base. In some embodiments, one or more tufts of artificial eyelash extension are indirectly connected to at least one adjacent tuft of artificial eyelash extension at the base.

In some embodiments, at least two artificial hairs of the artificial eyelash extension crisscross each other. For example, two artificial hairs of a particular cluster may cross each other. In some embodiments, the application of heat as described above may be used to form one or more individual artificial hair clusters. Thus, a cluster may have a base (e.g., a cluster base). As described above, the tufts may be arranged and heat may be applied to the tuft base to at least partially form the base (e.g., base 206) of the artificial eyelash extension.

In some embodiments, the artificial eyelash extension 200 or 300 may be 4mm to 10mm wide. In some embodiments, the artificial eyelash extension 200 or 300 may be 5mm to 6mm wide. In some embodiments, the width of the artificial eyelash extension is much wider than a single tuft, which is typically 1mm to 2mm wide.

The artificial eyelash extension 300 also shows adjacent artificial hairs (or adjacent clusters 304) coupled or secured to each other at the junctions 310A-310H (collectively referred to herein as "junctions 310") of the crisscrossed artificial hair 302. For example, at least one hair of a particular cluster may be secured (e.g., directly or indirectly) to one or more hairs of an adjacent cluster at the connection. In some embodiments, the connection may connect the artificial hair (e.g., a tuft) of the artificial eyelash extension together at an area between the two ends of the artificial hair such that the artificial hair of the artificial eyelash extension directly or indirectly connects to one another to form the artificial eyelash extension, and the two ends of the artificial hair are not connected together (e.g., open ended).

In some embodiments, the connection 310 may be considered a base, as described herein. In some embodiments, the connection may be formed by applying heat in a manner similar to that described herein. In some embodiments, the connection may be formed by applying pressure in a manner similar to that described herein. In some embodiments, the connection 310 may be formed using one or more of applying heat, applying an adhesive, applying pressure, or a chemical process as described herein. For example, crisscrossed artificial hair 302 is connected or secured together about 1mm to about 5mm (+/-0.5 mm) above end 306 (e.g., end 306 opposite end 308) of artificial hair 302.

In some embodiments, a synthetic material may be used to secure the tufts to each other over end 306 to form connection 310. In some embodiments, additional artificial material, such as one or more artificial hairs or other material, may be placed or attached horizontally with respect to the longitudinal direction of the artificial hair (e.g., across the area designated by the attachment portion 310). The artificial hair or clusters of artificial hair may be attached to the additional artificial material using one or more of the application of heat, the application of adhesive, the application of pressure, or a chemical process as described herein. In some embodiments, the application of additional artificial material for connecting artificial hair of the artificial eyelash extension 300 may be similar to the application of additional artificial material for forming a base as described herein.

In some embodiments, the base (similar to the base 206 of the artificial eyelash extension 200) may be formed and subsequently removed after the connection 310 is formed such that the artificial eyelash extension 300 does not include a base. In some embodiments, the fixed connection 310 may hold the artificial hair 302 of the artificial eyelash extension 300 together without a base. In some embodiments, the connection 310 of the crisscrossed artificial hair 302 may be formed without forming a base similar to the base 206 of the artificial eyelash extension 200.

In some embodiments, an artificial eyelash extension (such as artificial eyelash extension 200 or artificial eyelash extension 300) may be designed to be separable such that one or more artificial hairs and/or clusters may be detached from the artificial eyelash extension. In some embodiments, the one or more artificial hairs and/or clusters may be detached from the artificial eyelash extension using an applicator, as described herein. In some embodiments, the base and/or the connection may be frangible such that the artificial hair and/or cluster may be detached from the artificial eyelash extension by bending the base or connection of the artificial eyelash extension less than 45 degrees from a resting position (e.g., a flat base). For example, the clusters of artificial hair and/or artificial eyelash extensions may be designed such that the connection between the artificial hair and/or clusters can be broken with minimal force.

It should be understood that the artificial eyelash extensions 200 and 300 are provided for purposes of illustration and not limitation. In some embodiments, the artificial eyelash extension 200 and/or the artificial eyelash extension 300 may be used with an applicator, as described herein. In some embodiments, artificial lash extensions other than artificial lash extensions 200 and 300 may be used with an applicator, as described herein.

Fig. 4A is an illustration of an electrical applicator according to some embodiments of the present disclosure. The electrical applicator 400 is designed to apply heat to at least one or more natural lashes or one or more artificial lash extensions attached to the natural lashes. In some embodiments, the heated electrical applicator 400 (e.g., heating mode) may be used to curl one or more natural lashes or one or more artificial lash extensions attached to the natural lashes. In some embodiments, the heated electrical applicator 400 may be used to soften adhesives, such as existing adhesives, that attach the one or more artificial lash extensions to the natural lash. In some embodiments, the softened adhesive may be redistributed to the areas of the artificial lash extensions that contact the natural lash to help improve adhesion between the natural lash and one or more artificial lash extensions.

In some embodiments, the electrical applicator 400 is designed to at least cool one or more of the natural eyelashes, one or more artificial eyelash extensions attached to the natural eyelashes, or an adhesive that attaches the artificial eyelash extensions to the natural eyelashes. In some embodiments, the cooled electrical applicator 400 (e.g., cooling mode) may harden the adhesive between the artificial lash extension and the natural lash that has previously been softened and redistributed using the heated electrical applicator 400.

In some embodiments, for each arm 402, at least a portion of portion 410 is engaged with portion 408. End 426 of engaging portion 410 is closer to end 424 of portion 410 than to end 426 of portion 410. In some embodiments, portions 406, 408, and 410 extend longitudinally toward proximal end 404.

In some embodiments, for each arm 402, at least a portion of the inner surface 418 corresponding to the portion 410 includes a substantially planar surface (e.g., having a flatness control tolerance value of +/-0.5mm or +/-0.015 mm) (also referred to as substantially planar or flat). In some embodiments, the inner surface 418 extending between the end 424 and the end 426 of the portion 410 is substantially flat in whole or in large part (e.g., greater than 50%). In some embodiments, at least a portion of the inner surface 418 of the opposing arm 402 corresponding to the portion 410 is designed to apply pressure to one or more natural lashes or one or more artificial lash extensions disposed at (e.g., at the underside of) the natural lashes. For example, the flat inner surfaces of portions 410 are configured to bunch together and contact each other in the closed position. In some embodiments, the flat inner surface 418 extends from the apex 438 of the portion 410 toward the end 424 and the end 426 of each arm 402.

In some embodiments, for one or more of the arms 402, at least a portion of the outer surface 416 corresponding to the portion 410 includes a curved portion having a surface with a curve 430 positioned between the sides 412 and 414. In some embodiments, bend 430 extends between edge 412 and edge 414. In some embodiments, bend 430 is located between edge 412 and edge 414, but does not extend to the bottom between edge 412 and edge 414. In some embodiments, the bend 430 is a convex bend. In some embodiments, the curvature 430 of the curvature 432 is designed to curl one or more natural lashes or one or more artificial lash extensions disposed (or attached) at the natural lashes, such as at the underside of the natural lashes.

In some embodiments, the heating unit 446 may heat the respective surface of the portion 410 of each arm 402 to one or more temperatures in a temperature range of 77 degrees Fahrenheit (F) to 255F (e.g., 120F to 205F). In some embodiments, the temperature may be selected over one or more temperature ranges using, for example, switch 440.

In some embodiments, the electrical applicator 400 may include a temperature indicator that indicates the temperature of the electrical applicator 400. For example, the temperature of the electrical applicator 400 (e.g., at the respective surface of the portion 410 of each arm 402) may be displayed on a display (not shown) of the electrical applicator 400. The display may comprise, for example, a liquid crystal display.

In some embodiments, the heating unit 446 may include or be coupled to a heating member, such as heating member 448. In some embodiments, a heating member 448 may be disposed within each arm 402 of the electrical applicator 400. In some embodiments, a heating member extends within portion 410 of each arm 402. In some embodiments, the heating member conducts thermal energy (e.g., heat) to the portion 410 of each arm 402. In some embodiments, the heating member 448 may include a resistive wire. In some embodiments, the resistance wire is made of a non-magnetic nickel and chromium alloy, iron-nickel-aluminum, or iron-chromium-aluminum alloy. In some embodiments, the resistivity of the resistive wire is in the range of 0.1 ohm/cm (Ω/cm) to 0.5 ohm/cm, for example 0.225 ohm/cm. In some embodiments, the diameter of the resistive wire is in the range of 0.1mm to 2mm (e.g., the diameter is selected according to the operating temperature of the electrical applicator 400).

In some embodiments, the electrical applicator 400 may include a cooling unit 450. The cooling unit 450 may be configured to cool at least the inner surface 418 and/or the outer surface 416 of the portion 410 of each arm. In some embodiments, the cooling unit 450 cools the aforementioned surface below room temperature. In some embodiments, the cooling unit 450 may cool the aforementioned surface to one or more temperatures in the temperature range of 25F to 65F. In some embodiments, the electrical applicator 400 may be configured to cool at one or more temperatures of the temperature range.

In some embodiments, cooling unit 450 includes or is coupled to cooling member 452. In some embodiments, cooling unit 450 may conduct thermal energy away from cooling member 452 and away from the medium surrounding cooling member 451. In some embodiments, a cooling member 452 extends within a portion of each arm 402.

In some embodiments, the heating unit 466 may include a thermoelectric component (TEC). In some embodiments, the TEC may utilize the peltier effect to apply heat or cooling at the surface of the TEC. In some embodiments, the TEC may be a peltier device. In some embodiments, a TEC may comprise an array of alternating n-type and p-type semiconductors disposed between two plates (such as two ceramic plates). A voltage applied to the TEC cools one plate and heats the opposite plate. For example, a voltage may be applied to the TEC such that one plate generates heat and the opposite plate cools. The heating member 448 may be thermally coupled to a heating plate of the TEC, and thermal energy generated to the TEC may be transferred to the heating member 448.

In some embodiments, the cooling unit 450 may also include a TEC. In some embodiments, the TEC of the cooling unit 450 may be different from the TEC of the heating unit. In some embodiments, the TEC of the cooling unit 450 may be the same TEC as used in the heating unit 446. In some embodiments, only one of the heating unit 446 or the cooling unit 450 includes a TEC. In some embodiments where the cooling unit 450 includes a TEC, a voltage may be applied to the TEC to cool one plate of the TEC. The cooling member 452 may be thermally coupled to the cooling plate, and thermal energy can be removed from the cooling member and/or the medium surrounding the cooling member 452.

In some embodiments, the cooling member 452 and the heating member 448 are different members. In some embodiments, the heating member 448 and the cooling member 452 are the same member. In an illustrative example, the heating/cooling member can be thermally coupled to one side of the TEC. The polarity of the voltage coupled to the TEC can be switched so that the thermal coupling plate of the TEC can be switched from heating to cooling and vice versa as desired.

In some embodiments, the electrical applicator 400 includes a power source, such as a battery 444. In some embodiments, battery 444 may be a rechargeable battery. In other embodiments, the battery 444 may be a disposable battery, such as an alkaline battery, which may be replaced by, for example, a user.

In some embodiments, the electrical applicator 400 includes one or more power electronics 442, the one or more power electronics 442 converting external energy into usable energy of the battery 444. For example, the battery 444 may be charged using an inductive charger. The power electronics 442 may include coils and other suitable electronics that collect magnetic energy transmitted by the inductive charger. In some embodiments, the power electronics 442 may include an AC-to-DC converter (and/or rectifier). For example, the electrical applicator 400 may have a physical connection (e.g., a wire) to an electrical outlet. The power electronics 442 may convert AC power to constant or pulsed DC that charges the battery 444, or directly power the electrical applicator 400 (e.g., the heating unit 446 and/or the cooling unit 450).

In some embodiments, the electrical applicator 400 includes a switch 440. The switch 440 may be used to turn the electrical applicator 400 on or off. In some embodiments, the switch 440 may control the state of the electrical applicator 400 from a cooling state (e.g., cooling mode) to a heating state (e.g., heating mode), and vice versa. In some embodiments, the switch 440 may control the temperature in one or more of a cooling state or a heating state. For example, the switch 440 may be a rotary switch that allows a user to rotate the switch to control the temperature of the electrical applicator 400 in either a cooled state or a heated state. In some embodiments, the switch 440 is electrically coupled to one or more of the battery 444, the heating unit 446, or the cooling unit 450.

In some embodiments, the electrical applicator 400 includes an off timer (not shown). After the temperature of the heating unit 446 or the cooling unit 450 reaches the set temperature, the switch 440 in the on position automatically reaches the off position within a preset time (e.g., after 5 minutes) to cut off power to one or more of the heating unit 446 or the cooling unit 450.12.

Fig. 5A-5G are diagrams illustrating operations for attaching an artificial eyelash extension to a natural eyelash and curling the attached natural eyelash using an electrical applicator, according to some embodiments of the present disclosure. For purposes of illustration and not limitation, reference is made to the elements of the preceding figures with respect to the description of fig. 5A-5G.

Fig. 5A illustrates the application of an adhesive to natural lashes according to some embodiments of the present disclosure. Fig. 5A shows adhesive 554 applied to the underside of the upper natural eyelashes 552 of the eye 550 using an adhesive applying tool 556 (e.g., a brush). The adhesive may include one or more of glue, mascara, adhesive, epoxy, paste, or any other natural or synthetic substance having adhesive qualities.

Fig. 5B illustrates an arrangement of an artificial eyelash extension at a natural eyelash, according to some embodiments of the present disclosure. Fig. 5B shows a first set of artificial eyelash extensions 500A-500E (generally referred to herein as "artificial eyelash extensions 500") disposed at the underside of a natural eyelash of a user's eye. In some embodiments, each of the artificial eyelash extensions 500A-500E includes a base 506A-506E, respectively. The bases 506A-506E may be disposed on the underside of the natural eyelashes 552. In some embodiments, the bases 506A-506E are disposed near the line of lashes of the eye 550. In some embodiments, at least a portion of the top sides of the bases 506A-506E are attached (via adhesive) to the underside of the natural eyelashes 552. In some embodiments, at least a portion of some artificial hair of the artificial eyelash extension 500 is attached (via an adhesive) to the underside of the natural eyelashes 552. It should be understood that the size, number, and type of artificial eyelash extensions are shown for purposes of illustration and not limitation. In some embodiments, any number of artificial lash extensions may be attached to the natural lash. Although the artificial eyelash extension is shown as a portion of a given size, in other embodiments the artificial eyelash extension may be a larger portion (or smaller portion) that extends, for example, across about half of the line of lashes (e.g., two artificial eyelash extensions may cover the upper lashes). In other embodiments, a single artificial eyelash extension may substantially cover the ciliary lines. In some embodiments, different types of artificial lash extensions may be used.

Fig. 5C illustrates an artificial eyelash extension attached to a natural eyelash, according to some embodiments of the present disclosure. Fig. 5C shows artificial lash extensions 500A-500E attached to the underside of a natural lash using an applicator. The applicator as shown may be the same or a different applicator as described herein. For example, a purely mechanical applicator may be used to attach an artificial eyelash extension to the underside of a natural eyelash. In some embodiments, the inner surfaces of the arms of the applicator may apply pressure to the artificial eyelash extension and the natural eyelashes and provide a stronger bond of the artificial eyelash extension to the natural eyelashes (stronger than if no additional pressure was applied). The application of pressure may result in an increase in the bonding surface of the artificial lash extension and natural lash (over the case where no pressure is applied). In some embodiments, a user may apply pressure to the applicator that brings the opposing arms together and applies pressure to the artificial eyelash extension, the adhesive, and the natural eyelashes therebetween. The pressure may help secure or adhere the artificial eyelash extension to the natural eyelashes.

In some embodiments, the electrical applicator 400 is used to attach an artificial eyelash extension to a natural eyelash. When attaching the artificial eyelash extension to the natural eyelash, the electrical applicator 400 may be in a heated state, a cooled state, or an off state.

Fig. 5D illustrates the positioning of an electrical applicator in an aligned orientation according to some embodiments of the present disclosure. Fig. 5D shows a heated electrical applicator 400 positioned at an eye region in an aligned orientation. In the aligned orientation, the curved portion 428 of each arm 402 is aligned with the line of eyelashes of the natural eyelashes. In some embodiments and not shown in fig. 5D, the electrical applicators 400 are obtained and activated such that the heating units of the electrical applicators 400 are activated to heat the portions 410 of each arm 402 to a desired temperature. As shown, the electrical applicator 400 may be positioned in an aligned orientation when in an open position.

Fig. 5E illustrates a transition of an electrical applicator to a closed position according to some embodiments of the present disclosure. Fig. 5E illustrates the heated electrical applicator 400 transitioned from an open position (e.g., as shown in fig. 5D) to a closed position by closing the natural eyelashes and the portions 410 of the pair of opposing arms 402 attached (e.g., attached) to the artificial eyelash extension 500 of the natural eyelashes. In some embodiments, particularly for curling one or more of the natural or artificial eyelash extensions 500, the heated electrical applicator 400 may be positioned toward or closer to the end of the natural or artificial eyelash extension 500 (e.g., away from the ciliary line or base, respectively). The heated electrical applicator 400 in the closed position is shown in an aligned orientation.

Fig. 5F illustrates a heated electrical applicator rotated to a rotated orientation according to some embodiments of the present disclosure. In some embodiments, the heated electrical applicator 400 is rotated in a closed position along the axis of rotation to transition the heated electrical applicator 400 from the aligned orientation to the rotated orientation. In the rotational orientation, at least a portion of the natural eyelashes and at least a portion of the artificial eyelash extension contact an outer surface 416 of the portion 410 of at least one of the pair of opposing arms 402 of the heated electrical applicator 400. In some embodiments, one or more of the inner surface 418 or the outer surface 416 of the portion 410 of the heated electrical applicator 400 is heated to a desired temperature in a heated state. As shown, the outer surface 416 of the portion 410 has a curvature 430 that facilitates curling one or more natural or artificial eyelash extensions.

In some embodiments, the heated electrical applicator 400 is maintained in the rotated orientation and closed position for a period of time (e.g., 5-60 seconds) to curl (e.g., set the curl such that the curl remains after the electrical applicator 400 is removed) one or more natural or artificial eyelash extensions 500.

For purposes of illustration and not limitation, a curved artificial eyelash extension is shown. In some embodiments, the electrical applicator 400 may be used to curl natural lashes without artificial lash extensions in a similar manner as described herein.

Fig. 5G illustrates a curled artificial eyelash extension and natural eyelashes, according to some embodiments of the present disclosure. In some embodiments, after maintaining the heated electrical applicator 400 in the closed position and the rotational orientation for a period of time, the heated electrical applicator 400 may be removed to expose one or more natural or artificial eyelash extensions 500 in the curled position (e.g., more curled than at least prior to performing the above-described operations to curl the artificial or natural eyelash extensions).

Fig. 6A-6F are diagrams illustrating operations for reattaching an artificial eyelash extension to a natural eyelash, according to some embodiments of the present disclosure. For purposes of illustration and not limitation, reference is made to the elements of the preceding figures with respect to the description of fig. 6A-6F.

Fig. 6A illustrates an artificial eyelash extension that has been attached to a natural eyelash, according to some embodiments of the present disclosure. In some embodiments, the artificial eyelash extension 500 may be attached or disposed to natural eyelashes, as described above with respect to fig. 5A-5C. For brevity, in some embodiments, the description with respect to fig. 5A-5C may be applied to fig. 6A and is not repeated here. In some embodiments, the artificial eyelash extension 500 may be curled as described herein. In other embodiments, the artificial eyelash extension is not curled using the electrical applicator 400.

In some embodiments, the artificial eyelash extension 500 is attached (e.g., arranged and/or attached) during the first application period. In some embodiments, the operations described below with respect to fig. 6B-6F are performed during the second application period. The second application period (reattachment) may be performed after a certain period of time (e.g., hours or days) after the first application period is performed. In some embodiments, a second period of reattachment operation may be performed to re-bond or enhance the bond between the artificial lash extension and the natural lash.

Fig. 6B illustrates the positioning of an electrical applicator in an aligned orientation according to some embodiments of the present disclosure. Fig. 6B shows the heated electrical applicator 400 positioned at the eye region in an aligned orientation. In the aligned orientation, the curved portion 428 of each arm 402 is aligned with the line of eyelashes of the natural eyelashes. In some embodiments and not shown in fig. 6B, the electrical applicators 400 are obtained and activated such that the heating units of the electrical applicators 400 are activated to heat the portions 410 of each arm 402 to a desired temperature. The electrical applicator 400 is also shown in an open position.

Fig. 6C illustrates transitioning an electrical applicator to a closed position according to some embodiments of the present disclosure. Fig. 6C illustrates the heated electrical applicator 400 transitioned from an open position (e.g., as shown in fig. 6B) to a closed position by closing portions 410 of the pair of opposed arms 402 onto the natural and artificial eyelash extensions 500 therebetween. In some embodiments, particularly for reattaching the artificial eyelash extension 500, the heated electrical applicator 400 may be positioned toward or closer to the natural eyelashes or the base of the artificial eyelash extension 500 (e.g., away from the end of the artificial eyelash extension). The heated electrical applicator 400 in the closed position is shown in an aligned orientation.

In some embodiments, to perform the reattachment operation, the heated electrical applicator 400 is maintained in the closed position (and in the aligned orientation or another orientation) for a period of time (e.g., 5-300 seconds) to soften the adhesive used to attach (e.g., arrange and/or attach) the artificial lash extension 500 to the natural lash. In some embodiments, the adhesive may be a raw adhesive for placement and attachment of the artificial eyelash extension during an initial application period (see, e.g., fig. 5A). In some embodiments, additional adhesive may be applied. In some embodiments, no additional adhesive is applied (e.g., other than the initial application period). For example, the adhesive bonding the artificial eyelash extension to the natural eyelashes may be old adhesive several days ago and have hardened during that time period. The introduction of heat to the hardened adhesive may soften the adhesive and allow the adhesive to reflow or redistribute to different contact areas between the artificial lash extension and the natural lash.

Fig. 6D illustrates an artificial eyelash extension after a heated electrical applicator has been removed, according to some embodiments of the present disclosure. Fig. 6D shows the artificial eyelash extension after the heated electrical applicator 400 is removed from the eye region. The adhesive has been heated and may still be tacky or sticky. In some embodiments, the cooling unit 450 of the electrical applicator 400 may be activated to cool the portion 410 of each arm 402 of the electrical applicator 400.

Fig. 6E illustrates a cooled electrical applicator positioned in an aligned orientation and a closed position according to some embodiments of the present disclosure. In some embodiments, the cooled electrical applicator 400 may be positioned at the eye region in an aligned orientation in an open position (not shown, but similar to fig. 6B). In the aligned orientation, the curved portion 428 of each arm 402 is aligned with the line of eyelashes of the natural eyelashes. In some embodiments, the cooling unit 450 of the electrical applicator 400 is activated to cool the portion 410 of each arm 402 to a desired temperature.

In some embodiments, the cooled electrical applicator 400 transitions from an open position (e.g., similar to fig. 6B) to a closed position by closing the natural eyelashes and portions 410 of the pair of opposing arms 402 attached (e.g., attached) to the artificial eyelash extension 500 of the natural eyelashes. In some embodiments, particularly for reattaching the artificial eyelash extension 500, the cooled electrical applicator 400 may be positioned toward or closer to the line of eyelashes of the natural eyelashes or the base of the artificial eyelash extension 500 (e.g., the end distal from the artificial eyelash extension). The cooling power applicator 400 in the closed position is shown in an aligned orientation (but may be in a different orientation in some embodiments).

In some embodiments, to perform the reattachment operation, the cooled electrical applicator 400 is maintained in the closed position (and in the aligned orientation or another orientation) for a period of time (e.g., 5-180 seconds) to harden the adhesive used to attach the artificial lash extension 500 to the natural lash. In some embodiments, the time between heating the adhesive and cooling the heated adhesive may be less than 5 minutes or at least during the same application period. By cooling the adhesive, the adhesive hardens to reform and even improve the bond between the artificial eyelash extension and the natural eyelashes.

Fig. 6F illustrates an artificial eyelash extension after a cooled electrical applicator has been removed, according to some embodiments of the present disclosure. Fig. 6F shows the artificial eyelash extension after removal of the cooled electrical applicator 400 from the eye region. The adhesive has been heated and subsequently cooled. Although the electrical applicator 400 has been used to illustrate cooling of the adhesive, in some embodiments, a different applicator may be used. For example, as described herein, a purely mechanical applicator (e.g., a metal applicator) may be placed in the freezer and subsequently used to perform cooling.

The method 700 is described as a series of acts (or actions). It should be understood that some operations may be performed concurrently with other operations. In some embodiments, the same, fewer, or greater number of operations may be performed in the same or different order. In some embodiments, different operations may be performed, or multiple operations may be combined into a single operation, or multiple operations may be used to perform a single operation.

Fig. 7A to 7C are flowcharts illustrating operations for attaching an artificial eyelash extension, curling the artificial eyelash extension, and reattaching the artificial eyelash extension, according to an embodiment of the present disclosure. The method 700 of fig. 7A-7C may be performed by a user. In some embodiments, a user may perform at least some operations of method 700 using electrical applicator 400 or a different applicator as described herein. The user of method 700 may be the same user on whom the artificial eyelash extension is applied or another user who applies the artificial eyelash extension on behalf of the user.

At operation 705 of the method 700, an adhesive may be applied to the user's natural eyelashes. In some embodiments, the adhesive may be applied to the underside of the natural eyelashes, such as the underside of the upper natural eyelashes. In some embodiments, the adhesive may be applied to the top or side of the upper natural eyelashes, rather than the underside.

In some embodiments, the adhesive may be one or more of a glue, a mascara, a binder, an epoxy, a paste, or any other natural or synthetic substance having adhesive qualities. In some embodiments, the adhesive may be a waterproof formulation that allows the artificial eyelash extension (and/or the artificial hair from which it is detached) to remain attached to the individual's natural eyelashes for a period of time (e.g., hours, days, weeks, or months). In some embodiments, the adhesive may be a commercially available adhesive for conventional lash extensions or a proprietary composition for lash extensions described herein. The adhesive may be transparent or colored (e.g., milky white or black to simulate mascara).

In some embodiments, the adhesive may be applied using a brush, comb, or any other type of application tool. In some embodiments, the adhesive may be applied 1 to 2 millimeters from the waterline. In other embodiments, the adhesive may be applied at any location along the natural eyelashes or along the water line. In some embodiments, it may be desirable to wait a predetermined period of time before proceeding to operation 710 to allow the adhesive to activate (e.g., partially cure or dry) its adhesive quality.

At operation 710, a user places one or more artificial eyelash extensions at a user's natural eyelashes. In some embodiments, the one or more artificial eyelash extensions may be disposed at the underside of the natural eyelashes. In some embodiments, the top side of each base of each artificial eyelash extension may be disposed directly to the underside of the natural eyelashes (rather than the eyelids). In some embodiments, the one or more artificial lash extensions may be arranged to align with a curvature of a lash line. For example, a plurality of artificial lash extensions may be disposed adjacent to one another (e.g., not overlapping or overlaying) such that the base is aligned with the curvature of the lash thread. Thus, when the artificial eyelash extension is placed close to the line of lashes, the one or more artificial eyelash extensions may become substantially flush with the line of lashes.

In some embodiments, one or more artificial eyelash extensions may be disposed at the underside of the natural eyelashes at a time. For example, a single artificial eyelash extension may be disposed first, another artificial eyelash extension may be disposed later, and so on. In some embodiments, an applicator (such as electrical applicator 400) may be used to dispose the one or more artificial eyelash extensions. The user may also rearrange one or more artificial lash extensions as desired.

In some embodiments, disposing one or more artificial lash extensions at the user's natural lash includes disposing the one or more artificial lash extensions adjacent to one another at the natural lash.

In some embodiments, the artificial eyelash extension disposed at the natural eyelashes may include one to eight different artificial eyelash extensions. The number of artificial eyelash extensions disposed at the natural eyelashes may be based on the width of the artificial eyelash extension, the thickness of the artificial hair used, the desired style, the desired eyelash density (also referred to as the "fullness" of the user's eyelashes), and the like.

In some embodiments, instead of applying adhesive to the natural eyelashes (as discussed at operation 705) and then disposing the one or more artificial eyelashes extensions to the natural eyelashes (as discussed at operation 710), adhesive may be applied to the one or more artificial eyelashes extensions (e.g., the top side thereof), and then disposing the artificial eyelashes extensions at the natural eyelashes (e.g., the underside thereof).

At operation 715, the user may attach the artificial eyelash extension to the natural eyelash. In some embodiments, each artificial eyelash extension may be attached (e.g., bonded) to the underside of the natural eyelashes. In some embodiments, once the one or more artificial lash extensions are arranged in a desired arrangement, the artificial lash extensions are secured to a surface (such as the underside of the natural lash) and more permanently attached to the surface (e.g., days). In some embodiments, as described herein, one or more applications of pressure using the electrical applicator 400 or different applicators or times for curing the adhesive may be used to aid in attaching the separated artificial hair.

In some embodiments, operations 705 through 715 are performed during the first application period. In some embodiments, one or more of operations 720 through 775 are performed during the second application period. In some embodiments, the second application period is performed a time period subsequent to the first application period. For example, the period of time may be greater than 6 hours or greater than 1 day. In some embodiments, one or more of operations 705 through 775 may be performed during the same application period.

At operation 720, an electrical applicator 400 is obtained. In some embodiments, the electrical applicator 400 includes a pair of opposing arms and a heating unit. Each arm includes a first portion (e.g., portion 410) having a first bend (e.g., bend 428) disposed between a first end (e.g., end 424) and a second end (e.g., end 426) of the first portion.

In some embodiments, each arm further includes a first edge (e.g., edge 412) opposite a second edge (e.g., edge 414) and an inner surface (e.g., inner surface 418) opposite an outer surface (e.g., outer surface 416). The inner and outer surfaces extend between the first and second edges.

In some embodiments, the first portion of each arm includes a second bend (e.g., bend 434) disposed between the first end and the second end and along at least a portion of the first side corresponding to the first portion. In some embodiments, the second bend is positioned opposite the first bend. In some embodiments, the first bend is disposed along at least a portion of the second edge corresponding to the first portion. In some embodiments, the first bend is a concave bend and the second bend is a convex bend.

In some embodiments, at least a portion of the inner surface corresponding to the first portion comprises a substantially planar surface. In some embodiments, at least a portion of the inner surface corresponding to the first portion of the opposing arms is designed to apply pressure to the natural eyelashes and the artificial eyelash extension attached thereto.

In some embodiments, at least a portion of the outer surface corresponding to the first portion includes a surface having a third bend (e.g., bend 430) extending between the first and second edges. In some embodiments, at least a portion of the outer surface corresponding to the first portion is designed to curl one or more of the natural eyelashes or an artificial eyelash extension attached to the natural eyelashes.

At operation 725, the user activates the heating unit of the electrical applicator. In some embodiments, activating the heating unit may heat the first portion of each arm to a desired temperature.

At operation 730, the heated electrical applicator is positioned at an eye region of the user in an aligned orientation. In some embodiments, in the aligned orientation, the first curved portion of each arm is positioned to align with a lash line of a natural lash. In some embodiments, the heated electrical applicator is positioned in an aligned orientation when in the open position.

At operation 735, the heated electrical applicator is transitioned to a closed position. In some embodiments, the heated electrical applicator is transitioned to the closed position by closing a first portion of the pair of opposing arms on the natural eyelashes and the artificial eyelash extension attached to the natural eyelashes. In some embodiments, if advanced to branch a (e.g., curl the natural eyelashes and/or artificial eyelashes extensions), the first portion of the heated electrical applicator may close over the natural eyelashes and/or artificial eyelashes extensions near the ends of the natural eyelashes and/or artificial eyelashes extensions. In some embodiments, if advanced to branch B (e.g., reattach the artificial eyelash extension), the first portion of the heated applicator may close over the natural eyelashes and/or the artificial eyelash extension, respectively, near the line or base.

In fig. 7B, at operation 740 of branch a, the heated electrical applicator in the closed position is rotated to a rotated orientation. In some embodiments, the user rotates the heated electrical applicator in the closed position along the axis of rotation to transition the heated electrical applicator from the aligned orientation to the rotated orientation. In some embodiments, in the rotational orientation, one or more of at least a portion of the natural eyelashes or at least a portion of the artificial eyelash extension contacts an outer surface of a first portion of at least one of the pair of opposing arms of the heated electrical applicator.

At operation 745 of branch a, the heated electrical applicator is maintained in the closed position and the rotational orientation for a period of time to curl one or more of the natural eyelashes or the artificial eyelash extension.

In fig. 7C, at operation 750 of branch B, the heated electrical applicator is maintained in the closed position for a period of time. In some embodiments, the heated electrical applicator is maintained in the closed position for a period of time to soften the adhesive used to attach the artificial eyelash extension to the natural eyelashes.

At operation 755 of branch B, the heated electrical applicator is removed from the eye region.

At operation 760 of branch B, the cooling unit of the electrical applicator is activated. In some embodiments, activating the cooling unit cools at least a first portion of each arm.

At operation 765 of branch B, the cooled electrical applicator is positioned at the eye region of the user. In some embodiments, the cooled electrical applicator is positioned in an aligned orientation when in the open position.

At operation 770 of branch B, the cooled electrical applicator is transitioned to the closed position.

At operation 775 of branch B, the cooled electrical applicator is maintained in the closed position for a period of time. Maintaining the cooled electrical applicator in the closed position may harden the adhesive used to attach the artificial eyelash extension to the natural eyelashes.
