DESCRIPTION

Technical field

The present invention relates to the aesthetic sector. More specifically, that disclosure relates to the eyebrow project.

Technological context

The background of the present invention is introduced hereinafter with the discussion of techniques relating to its context. However, even when this discussion concerns documents, deeds, artifacts and the like, it does not suggest or recognize that the techniques discussed are part of the known art or are general knowledge in the relevant sector for the present invention.

The eyebrows (that is, the two skin reliefs covered with small bristling hairs that follow the orbital arch) have a significant impact on the aesthetic appearance of each person. In fact, the eyebrows, due to their prominent position between the eyes and the forehead, are very important in the harmony of the person's face. However, brows typically have natural imperfections (for example, in shape and color). Furthermore, the eyebrows can be damaged, for example, by thinning out until they disappear completely; this may be due to poor hair removal, old age, specific diseases (such as alopecia), side effects of particularly heavy treatments (such as chemotherapy) and so on.

Various techniques are available for drawing the eyebrows; this allows you to restore the original appearance of the eyebrows (in case of their damage) and / or to improve their appearance (in terms of both shape and thickening). In general, these techniques (eyebrow drawing) are based on a drawing tool that is able to color the skin of the person. The drawing tool can be a simple makeup pencil, a dermo-pigmentation pen (as in micro-incision technology, micro-blading) or a tattoo machine (as with needles); the makeup pencil deposits a colored paste on the skin (with a temporary effect, as for a few hours), the dermo-pigmentation pen introduces colored pigments into the epidermis (with a semi-permanent effect, as for a few months) and the tattoos introduces colored pigments into the dermis (with a permanent effect).

In any case, the drawing of the eyebrows is preceded by a phase of designing their desired shape on the person's face. This is necessary both when you want to simply follow the natural shape of the eyebrows and when you want to give the eyebrows particularly pleasing shapes from an aesthetic point of view (for example, gull-wing or soft angled to create a glamorous effect or rounded for create a sweet effect).

To do this, it is necessary to mark some reference points on the face to follow with the drawing tool. For example, in the 3-point technique for each eyebrow a vertical stroke is drawn from the outer edge of the corresponding nostril (from which the eyebrow will start). Then, a line is drawn between the nostril and the corresponding pupil (which defines the highest point of the eyebrow). Finally, a line is drawn between the nostril and the outer edge of the corresponding eye (where the eyebrow will end). For this purpose, the operator can help himself with a ruler (rigid or flexible).

In any case, the design of the eyebrows is a rather complex operation. In fact, it is difficult to define the reference points correctly, especially in the same way for the two eyebrows.

Consequently, it is possible to have corresponding errors in the design of the eyebrows, and in particular more or less marked differences between the two eyebrows. This exposes you to the risk of anti-aesthetic defects, which are particularly serious in the case of the semi-permanent effect of the eyebrows and completely unacceptable in the case of the permanent effect of the eyebrows.

The operator can also try to manually correct errors (if and as far as possible). However, this involves a greater expenditure of time and in general a less than optimal aesthetic effect.

In any case, the eyebrow design is a very long process; moreover, the results obtained strongly depend on the skills and experience of the operator.

The above has a negative impact on the quality and cost of the eyebrow design.

Detailed description

With reference in particular to FIG. 1, an illustrative representation of an embodiment of the present invention is shown.

In particular, a measuring device 100 is used to design eyebrows on a person's face. For this purpose, the measuring device 100 comprises the following components.

A support component, or simply support 105 (for example, a frame of glasses) is suitable to be worn on a person's head (in their own condition). The support 105 has a support element 110, which rests on a person's nose (in the condition of use). The support 105 is equipped with two guides 115a and 115b; the guides 115a, 115b are symmetrical with respect to the support element 110, so as to be arranged on opposite sides of the nose, on the left and on the right, respectively (in the condition of use). Two sliding components, for example, rulers 120a and 120b are mounted on the support 105; the rulers 120a and 120b slide along the guides 115a and 115b, respectively. The support 105 is graduated along the guides 115a, 115b to measure corresponding positions of the rulers 120a, 120b with respect to the support 105; for this purpose, a graduated scale (or more) 125a and 125b, for example, in cm and mm, is drawn along the guide 115a and 115b, respectively, on a front face of the support 105 which faces away from the face ( in the condition of use). Additionally or alternatively, the rulers 120a, 120b are graduated to measure corresponding positions on the face; for this purpose, a graduated scale (or more) 130a and 130b, for example, again in cm and mm, is drawn along the ruler 120a and 120b, respectively, on a front face which faces away from the face (in the condition of use). For example, each ruler 120a, 120b has a length of 5-15 cm and is equipped with two graduated scales at its longitudinal edges; a graduated scale extends from one of its longitudinal ends while a different graduated scale extends from both sides of one of its central positions.

In order to design the eyebrows on the person's face, the holder 105 is worn on his head. In this way, the support 105 remains stably in position, so as to operate as a (fixed) body of a caliper to perform the necessary measurements to establish the desired shape of the eyebrows. The rulers 120a and 120b, on the other hand, can move along the guides 115a and 115b, respectively, so as to act as sliders for the gauge to mark the reference points to follow to draw the eyebrows on the face (for example, in the 3-point technique).

The measuring device 100 greatly simplifies the design of the eyebrows. In particular, the rulers 120a, 120b can be positioned with precision (thanks to the graduated scales 125a, 125b along the guides 115a, 115b) with respect to the face (thanks to the support 105 in a stable position with respect to it) to perform very precise measurements (thanks to graduated scales 130a, 130b). This makes it easy to define the reference points correctly, especially in the same way for the two eyebrows.

Consequently, the risks of errors in the design of the eyebrows are eliminated (or at least greatly reduced); this is particularly advantageous in the case of a semi-permanent effect and especially in the case of a permanent effect of the eyebrows. At the same time, the need to manually correct errors is substantially reduced; this involves less time and a better aesthetic effect.

In any case, the proposed solution allows you to design your eyebrows very quickly; moreover, this allows highly reproducible results to be obtained (as they are less dependent on the skills and experience of corresponding operators).

The above has a positive effect on the quality and cost of the eyebrow design.

With reference now to FIG. 2, a schematic representation of the measuring device 100 according to an embodiment of the present invention is shown,

In this case, the support 105 is shaped like an eyeglass frame (indicated with the same reference). For example, the frame (of glasses) 105 is made of hypoallergenic material of a synthetic type (such as celluloid, cellulose acetate, polyamide, polymethylmethacrylate, Megol and so on) and / or of a metallic type (such as aluminum, titanium and so on) . This makes the measuring device 100 very practical and simple to produce at low cost.

A front part of the frame 105 comprises a front formed by two rings 205a and 205b (without any lenses inside them) joined together by a bridge 210.

Starting from the rings 205a and 205b, for example, they have a square shape, each with a size of 5-10 cm x 10-15 cm, a width of 0.5-2.0 cm and a thickness of 0.1- 1.0 cm. The rings 205a and 205b house the guides 115a and 115b, respectively. In particular, the guides 115a, 115b extend along the entire rings 205a, 205b so as to also have a closed ring shape, with an upper section and a lower section substantially horizontal and an internal section and an external section transverse to the direction horizontal, for example, substantially vertical (in the condition of use). This allows a wide freedom of movement of the rulers 120a, 120b and makes the proposed solution very versatile. Two locking elements 215a and 215b (for example, screw) are associated with the rulers 120a and 120b, respectively. Each locking element 215a, 215b is adjustable between a passive condition (in which it allows the corresponding ruler 120a, 120b to move relative to the mount 105, both in translation and in rotation) and an active condition (in which it prevents the corresponding ruler 120a, 120b to move relative to the support 105). This further improves the accuracy of the results obtained.

Moving on to bridge 210, for example, it has a generically rectangular shape, with a height of 2-5 cm and a width of 1-2 cm. Bridge 210 is equipped with a central opening, for example, a slit 220 that extends vertically (in the condition of use); the slit 220 is used to mark a reference point, or zero point, on the face. Two nose pads (or wings) 225a and 225b extend towards the inside of the frame 105 from the rings 205a and 205b, respectively, to define the support element on the person's nose (not shown in the figure). Two rods 230a and 230b are hinged to the outer ends of the rings 205a and 205b, respectively, for example, to their lower outer edges (in the condition of use). The rods 230a, 230b are movable between a closed position and an open position. In the closed position, the rods 230a, 230b (as shown for the rod 230a in the figure) are folded over the rings 205a, 205b (partly overlapping each other) to reduce a footprint of the frame 105, for example, so as to allow store it in a corresponding case (not shown in the figure); in the open position, the rods 230a, 230b (as shown for the rod 230b in the figure) extend transversely (substantially perpendicularly) to the rings 205a, 205b to be worn on corresponding ears of the person (partially wrapping them in an anatomical way with their free end). An elastic lace or two substantially inextensible laces (not shown in the figure) can also be added between the free ends of the rods 230a, 230b to tighten the frame 105 on the person's head (in the condition of use) to further improve its stability. Furthermore, one or more spirit levels (not shown in the figure) can be added to determine corresponding inclinations; for example, a spirit level can be provided on deck 210 to check the horizontal arrangement of the mount 105 and / or a spirit level can be provided on each of the rulers 120a, 120b to check their vertical / horizontal arrangement.

With reference now to FIG.3A-FIG.3C, various examples of use of the measuring device 100 in accordance with an embodiment of the present invention are shown.

Starting from FIG.3A, an operator (for example, a beautician) puts the 105 frame on the person's head (possibly tightening it around his head using the corresponding laces). Once the frame 105 is correctly centered on the person's face, the operator marks the zero point (for example, with a make-up pencil) on the face through the slit 220; this allows to continuously check that the mount 105 remains in the correct position (with the zero point aligned with the slot 220). At this point, the operator can mark the other reference points for drawing the eyebrows (for example, again with the make-up pencil).

In particular, in the 3-point technique the operator frees one of the rulers, for example, the ruler 120a bringing its block element 215a to the passive condition. The operator moves the ruler 120a along the guide 115a (for example, in its lower portion) until it is arranged vertically next to the corresponding (left) nostril of the nose. The operator then stops the ruler 120a bringing its blocking element 215a to the active condition. At this point, the operator frees the other ruler 120b bringing its block element 215b to the passive condition. The operator moves the ruler 120b similarly along the guide 115b until it is arranged vertically next to the corresponding (right) nostril of the nose, in the same position along the graduated scale 130b where the ruler 120a is located along the graduated scale 130a. The operator then stops the ruler 120b bringing its blocking element 215b to the active condition. These operations can be repeated one or more times on each of the rulers 120a, 120b to refine their position, until they are in the same desired position along the graduated scales 130a, 30b. At this point, the operator marks two points on the face along the rulers 120a, 120b at the eyebrows (to indicate their beginning).

Moving on to FIG.3B, the operator frees one of the rulers, for example, the ruler 120a bringing its block element 215a to the passive condition. The operator moves the ruler 120a along the guide 115a (for example, still in its lower portion) and rotates it until it is placed between the corresponding nostril and the corresponding pupil (left). The operator then stops the ruler 120a bringing its blocking element 215a to the active condition. At this point, the operator frees the other ruler 120b bringing its block element 215b to the passive condition. The operator moves the ruler 120b similarly along the guide 115b and rotates it until it is placed between the corresponding nostril and the corresponding pupil (right), in the same position along the graduated scale 130b where the ruler 120a is located along the graduated scale 130a . The operator then stops the ruler 120b bringing its blocking element 215b to the active condition. These operations can be repeated one or more times on each of the rulers 120a, 120b to refine their position, until they are in the same desired position along the graduated scales 130a, 130b. At this point, the operator marks two points on the face along the rulers 120a, 120b at the eyebrows (to indicate their highest point).

Turning to FIG.3C, the operator frees one of the rulers, for example, the ruler 120a bringing its block element 215a to the passive condition. The operator moves the ruler 120a along the guide 115a (for example, in its lower / outer portion) and rotates it until it is placed between the corresponding nostril and the outer edge of the corresponding eye (left). The operator then stops the ruler 120a bringing its blocking element 215a to the active condition. At this point, the operator frees the other ruler 120b bringing its block element 215b to the passive condition. The operator moves the ruler 120b similarly along the guide 115b and rotates it until it is placed between the corresponding nostril and the outer edge of the corresponding (right) eye, in the same position along the graduated scale 130b in which the ruler 120a is located along the graduated scale 130a. The operator then stops the ruler 120b bringing its blocking element 215b to the active condition. These operations can be repeated one or more times on each of the rulers 120a, 120b to refine their position, until they are in the same desired position along the graduated scales 130a, 130b. At this point, the operator marks two points on the face along the rulers 120a, 120b at the eyebrows (to indicate their end).

With reference now to FIG.4, a schematic representation of a detail with detached parts of the measuring device 100 according to an embodiment of the present invention is shown.

The figure refers to a generic half of the measuring device, with the same considerations that also apply to the other half; therefore, for simplicity, the corresponding components will be indicated below, omitting their suffixes (“a” and “b”).

The guide 115 is defined by a channel 405 (for example, with a square section). The channel 405 is open (on the front face of the support 105) through a slot 410. The slot 410 is narrower than the channel 405, so as to define two (lateral) undercuts 415a and 415b. A shoe 420 comprises a body mating to the channel (for example, a small sphere with a flat bottom to prevent it from tilting). In this way, the shoe 420 can slide along the channel 405 remaining constrained inside it by the undercuts 415a, 415b. A side opening (not shown in the figure) can be provided in the channel 405 to insert / remove the shoe 420 during production and possibly for replacement operations (with the side opening which can be closed, possibly reversibly as with a sliding door). The shoe 420 is provided with a threaded hole 425 facing the slot 410 (extending perpendicularly thereto). A (longitudinal) slot 430 with a width matching that of the slot 410 is formed along the ruler 120. A screw 435 is screwed into the (threaded) hole 425. The screw 435 comprises a shank 440 and a head 445. The shank 440 it has a width conjugated to that of the slot 430 and of the slot 410, and has a portion proximal to the head 445 which is smooth and an end portion (distal from the head 445) which is threaded; the head 445 (for example, with a circular section with a knurled lateral surface to facilitate its maneuver), on the other hand, has a greater width than that of the slot 430. The shank 440 passes through the slot 430 protruding beyond the ruler 120 and therefore passes through the slot 410 reaching the hole 425 (for example, by fitting on washers or springs interposed between the head 445 and the ruler 120 and between the ruler 120 and the support 105). In this way, the shank 440 can slide along the slot 430 which acts as a (further) guide for it; at the same time, the head 445 constrains the ruler 120 between it and the support 105.

The screw 435 defines the locking element of the ruler 120. In particular, in the passive condition the screw 435 is loosened (for example, by turning it anti-clockwise) so that it does not act on the shoe 420 and on the ruler 120. Consequently, the shoe 420 is free to slide along the channel 405, thereby allowing the same movement to the ruler 120 which is coupled to the shoe 420 through the lateral interference of the shank 440 with the slot 430 (i.e., parallel to the front face of the support 105 ). In addition, the ruler 120 is free to rotate (through the slot 430) around the stem 440 (ie, around an axis of rotation perpendicular to the front face of the support 105). The shank 440 is also free to slide along the slot 430, thereby allowing the ruler 120 to slide with respect to the shank 440 (parallel to the front face of the support 105). On the contrary, in the active condition the screw 435 is tightened (for example, by turning it clockwise) so that the head 445 compresses the ruler 120 against the front face of the support 105 (thanks to the traction exerted on the shoe 420 through the shank 440). Consequently, the shoe 420 (and therefore also the ruler 120) cannot slide along the channel 405, the ruler 120 cannot rotate around the shank 440 and the ruler 120 cannot slide with respect to the shank 440.

Advantageously, it is possible to replace the ruler 120. For this purpose, for example, the screw 435 is removed by unscrewing it from the hole 425 (in an anti-clockwise direction) and extracting it from the slot 430, thereby allowing the ruler 120 to be removed. point, a new ruler (not shown in the figure) rests on the support 105 and the screw 435 is inserted through its slot and is screwed back into the hole 425 (clockwise).

With reference now to FIG.5, another example of use of the measuring device 100 in accordance with an embodiment of the present invention is shown.

In this case, the two rulers mounted on the guides 115a, 115b have been replaced with a new ruler 520 as indicated above (for example, mounting it on the guide 115a in the figure). The (new) ruler 520 has a similar structure to that of the (previous) rulers that have been replaced, with a graduated scale (or more) 530 being drawn along it. However, the 520 ruler is longer than the previous rulers (for example, equal to 1.5-3 times, such as 15-25 cm). This allows further measurements to be made (for example, horizontally, such as relative to the person's ears).

For example, one embodiment provides a measuring device for designing eyebrows on a person's face. However, the measuring device can be used to make any kind of measurements (for example, to mark any number of points of any kind), in order to design any type of eyebrows (for example, gull-wing, angled soft, rounded, straight, and so on) to be drawn in any way (for example, temporary, semi-permanent, permanent, and so on); furthermore, the eyebrows can be designed on any person's face (for example, woman, man, child / girl and so on) for any purpose (for example, retouching, restoration, beautification and so on).

In one embodiment, the measuring device comprises a support component that is suitable to be worn on a person's head in a condition of use. However, the support component can be of any type (for example, eyeglass frame, crown, and so on), of any size (for example, with different sizes, fixed or adjustable, and so on) and in any material ( for example, synthetic material, metal material, their combination, and so on).

In one embodiment, the support component has a support element to rest on a person's nose in the condition of use. However, the support element can be of any type (for example, two nose pads, a recess and so on).

In one embodiment, the support component has two guides that are symmetrical with respect to the support element so as to be arranged on opposite sides of the nose in the condition of use. However, the guides can be of any type (for example, channels, rails, rods, and so on), of any shape (for example, ring, horizontal, and so on), of any size and in any position (for example, centered on the eyes, arranged alongside the eyes, above and / or below the eyes, and so on).

In one embodiment, the measuring device comprises two sliding components. However, the sliding components can be of any type (for example, rigid, semi-rigid, flexible, and so on), of any shape (for example, bars, laths, with constant or variable section, and so on), of any size and of any material (both the same and different than the support component).

In one embodiment, the sliding components are mounted on the support component so as to be each sliding along a corresponding one of the guides. However, the sliding components can be coupled to the guides in any way (for example, by means of corresponding coupling elements, simply inserted on a support bar and so on); moreover, the sliding elements can be both independent and connected through a transmission mechanism that automatically moves them symmetrically with respect to the support element (each in response to the movement of the other).

In one embodiment, the support component is graduated along the guides to measure corresponding positions of each of the sliding components relative to the support component. However, the support component can be graduated in any way (for example, with any unit of measurement, starting reference, resolution, and so on) by means of graduated scales in any position and number (for example, one or more horizontal, one or more transversal, internal and / or external, and so on).

In one embodiment, each of the sliding components is graduated to measure corresponding positions on the face. However, each sliding component can be graduated in any way (both the same and different with respect to the supporting component) by means of graduated scales in any position and number (for example, one or more longitudinal, one or more transversal, on a single main face or different on two opposite main faces and so on); the sliding components can be used to measure any type and number of positions on the face (for example, the 3 points of the corresponding technique, points horizontally between the ears, points horizontally between the two eyebrows and so on).

More generally, it is possible to provide graduation only on the support component, only on one or both sliding components or any combination of them.

In one embodiment, each of the guides comprises at least a section that extends horizontally in the condition of use. However, the horizontal strokes can be in any position (for example, top, bottom, middle or their combination) and in any number (even zero).

In one embodiment, each of the guides comprises at least a section that extends in a transverse direction to the horizontal direction in the condition of use. However, the transverse strokes can be of any type (for example, vertical, oblique, curved or their combination), in any position (for example, internal, external central or their combination) and in any number (even zero).

In one embodiment, each of the guides comprises a ring section. However, the ring pattern can be of any type (for example, rectangular, round, oval, and so on) or it can be absent altogether.

In one embodiment, the sliding components are rotatably mounted with respect to corresponding coupling elements of the sliding components with the corresponding guides. However, the coupling components can be of any type (for example, skids, slides, carriages, and so on) and the rotation of the sliding components can be obtained in any way (for example, by means of a slot, joint, and so on).

In one embodiment, the sliding components comprise corresponding further guides for corresponding elements for coupling the sliding components with the corresponding guides. However, the coupling components can be of any type (see above) and the further guides can be of any type (for example, slot, channel, rail and so on).

More generally, the sliding components can be coupled to the sliding component so as to be able to slide along the guides, rotate with respect to the coupling elements, translate with respect to the coupling elements or any combination thereof.

In one embodiment, the measuring device comprises corresponding locking elements for the sliding components. However, the locking elements can be of any type (for example, a screw screwed into a shoe, a nut screwed into a pin integral with a shoe, with or without springs / washers and so on) or they can also be completely omitted. (for example, when the sliding components are frictioned to limit their accidental movements).

In one embodiment, each of the locking elements is adjustable between a passive condition (in which it allows the corresponding sliding component to move relative to the support component) and an active condition (in which it prevents the corresponding sliding component from moving relative to the component). support). However, the switching between the passive condition and the active condition can be achieved in any way (for example, by rotation, pressing / pulling and so on); in addition, the locking element can prevent the movement of the sliding component in any way (for example, by friction, by means of a pin / stop tooth and so on).

In one embodiment, each of the sliding components is removably mounted on the support component. However, this result can be obtained in any way (for example, by disassembling the coupling element of the sliding component with the guide, removing the coupling element through the lateral opening of the guide and so on); in any case, a simplified implementation in which the sliding components are not removable is contemplated.

In one embodiment, the measuring device comprises one or more further sliding components each mountable on the support component in replacement of at least one of the sliding components so as to be sliding along the corresponding guide. However, the additional sliding components can be in any number (even zero), of any type (both different and the same as each other and with respect to the sliding components) and can be used to replace any of the sliding components or both.

In one embodiment, each of the additional sliding components is graduated to measure corresponding positions on the face. However, each additional sliding component can be graduated in any way (both the same and different than the sliding components) to measure any type and number of positions on the face (see above).

In one embodiment, each of the further sliding components has a length greater than a common length of the sliding components. However, the further sliding components can have any length (for example, both the same and different from each other); in any case, the possibility is not excluded of having the further sliding components with equal and / or shorter lengths than the common length of the sliding components.

In one embodiment, the measuring device comprises a central opening for marking a reference mark on the face. However, the central opening can be of any type (for example, a slit, a recess and so on) or it can also be completely omitted.

In one embodiment, the support component is shaped like an eyeglass frame. However, the spectacle frame can be of any type (for example, with temples, pince-nez, and so on). More generally, the support component can have a different structure. For example, alternatively, the support component comprises a crown formed by a flexible strip at the free ends of which an elastic lace (or two substantially inextensible laces) is fixed; the crown is fitted on the head by expanding it elastically (or by coupling the two laces together, for example, by means of a knot or velcro).

In one embodiment, the support component comprises two rings. However, the rings can be of any type (for example, perimeter, round, pantos, mephisto and so on) or even replaced by two simple bars.

In one embodiment, each ring houses a corresponding one of the guides. However, the guides can be made in the rings in any way (for example, internally, superficially, and so on) and in any position (for example, along the entire rings or only along one or more of their parts and so on).

In one embodiment, the support component comprises a bridge joining the rings. However, the bridge can be of any type (for example, saddle, key, and so on).

In one embodiment, the support component comprises two nibs each coupled to a corresponding one of the rings to define the support element. However, the nose pads can be coupled to the rings in any way (for example, integral, mounted, and so on) and can be of any type (for example, fixed, semi-movable, movable, and so on).

In one embodiment, the support component comprises two rods each hinged to an external end of a corresponding one of the rings. However, the shafts can be of any type (e.g., curved, plain, diplo, golf, and so on) and hinged to the rings in any way (e.g., straight-nosed, swing-nosed, bent, curved, applied and so on), or they can also be completely absent (for example, by attaching an elastic lace or two inextensible laces as above directly to the front).

In one embodiment, the rods are movable between a closed position (in which they are folded over the rings to reduce a clutter of the support component) and an open position (in which they extend transversely to the rings to be worn on the person's corresponding ears. ). However, the rods can move in any way (for example, rotating in a rigid or elastic way, further flexing and so on).

In general, similar considerations apply if the measuring device has a different structure or includes equivalent components (for example, made of different materials) or has other operating characteristics. In any case, any of its components can be separated into several elements, or two or more components can be combined into a single element; moreover, each component can be replicated to support the execution of the corresponding operations in parallel. Furthermore, unless otherwise indicated, any interaction between different components generally does not need to be continuous, and can be either direct or indirect through one or more intermediaries.

One embodiment provides a method of designing eyebrows on a person's face. The method comprises wearing a support component on a person's head by resting a support member of the support component on a person's nose. The method comprises sliding two sliding components mounted on the support component each along a corresponding one of two symmetrical guides with respect to the support element which are arranged on opposite sides of the nose. The method comprises measuring corresponding positions of each of the sliding components relative to the support component by grading the support component along the guides. Additionally or alternatively, the method comprises measuring corresponding positions on the face by corresponding graduation of the sliding components. However, the method can be implemented by anyone (for example, an operator such as a beautician, directly by the person himself and so on).

In one embodiment, the method comprises marking the positions on the face. However, the positions can be in any number and type (see above) and can be marked in any way (for example, with a dot, a line, with a make-up pencil, an ink pen, and so on).

In one embodiment, the method comprises drawing at least one of the eyebrows on the face with reference to the marked positions. However, the eyebrows can be drawn in any way (see above).

In general, similar considerations apply if the same solution is implemented with an equivalent method (using similar steps with the same functions of several steps or their portions, removing some non-essential steps or adding additional optional steps); moreover, the steps can be performed in different order, in parallel or overlapping (at least in part).
