  This evaluation method can also be used for untreated eyelashes, for example, for treated eyelashes such as eyelashes with makeup when trying to evaluate the effect of the product.

  In the evaluation, the above-mentioned concave edge is placed almost along the eyelid so as to be on the eyelashes when the eyes are closed, and the eyelashes can be observed through the support.

  The length of the eyelashes can be determined by one or more scales that substantially coincide with the tips of the eyelashes.

  The density of the eyelashes can be evaluated in the same way, with the eyes closed, the concave edge (3) being in close contact with the eyelid, the support being guided over the eyelashes, and It can be evaluated by counting the number of eyelashes for each area in between.

  The degree of curvature of the eyelashes can be evaluated by placing the straight edge of the device substantially perpendicular to the line at the time of the eyelid with the eyes open, and reading the angle indicated by the direction of the eyelashes.

The present invention also provides
-Cosmetic or eyelash care products;
-For a set comprising an evaluation device as described above packaged with the product.

The invention also provides according to another feature:

  Such treatment can include applying a cosmetic product to the eyelashes, and in some cases, can include the use of an applicator, such as a heating comb, configured to bend and / or stretch the eyelashes.

  Furthermore, according to another feature, the present invention evaluates at least one of the length, density, and curvature of the eyelashes using a device as described above, and according to the evaluation result, the product to the eyelashes is evaluated. The present invention relates to a method for promoting a product to be applied to eyelashes, comprising a step consisting of enhancing the action.

  The present invention can be understood more clearly from the following detailed description and the accompanying drawings, which are given by way of non-limiting examples.

  The evaluation apparatus 1 shown in FIG. 1 includes a transparent support 2 made of, for example, a transparent thermoplastic material.

  The support 2 has an elongated shape with a concave edge 3 with a radius of curvature approximately matched to the curvature of the eyelid of the group to be evaluated, this radius of curvature being, for example, about 30 mm in the case of a Japanese group.

  The support 2 also comprises a straight edge 4 which is arranged on the same side as the concave edge 3 and which is continuous from the concave edge by a rounded part 6, for example of a radius of curvature of about 5 mm. The length of the straight edge 4 is, for example, 8 cm or more.

  The device 1 comprises a scale 10 for measuring the length of the eyelashes, with a series of scales 11 concentric with the concave edge 3 and radially spaced, for example, 1 mm from each other.

  The scale 10 can include, for example, a numerical scale 12 to indicate the distance from the corresponding scale to the concave edge 3.

  In order to inform the user of the average length of the eyelashes, for example the average length of 7 mm in this case, to the reference group, in the considered example Japanese group in the scale 11, the scale 13 It may be distinguished from the scale.

  The apparatus 1 also includes a density measuring scale 20 of the eyelash bundle, for example with a graduation 21 that is spaced equiangularly and extends radially, and in the embodiment considered, the graduation 21 is oriented perpendicular to the graduation 11. Has been.

  The two continuous graduations 21 are, for example, at an interval of about 1 mm at the intersection position with the graduations 13.

  The apparatus 1 includes a measurement scale 30 for measuring the degree of curvature of the eyelashes.

  The scale 30 includes a scale 31 that is arranged on the linear edge 4 and faces a direction intersecting at one point toward the center indicated by the mark 35. In some cases, the scale 31 is combined with a numerical display 32 to display the measurement angle α from the straight edge 4 to the corresponding scale.

  The scales of the respective scales 10, 20, 30 can be formed on the support 2 by, for example, unevenness and / or printing by appropriate etching of a mold.

  When measuring the length of the eyelashes, the device 1 can be applied to the eyelash bundle when the eyes are closed as shown in FIG. 2, and the concave edge 3 is substantially in contact with the eye lid and Guided to the base.

  The length of the eyelashes is given by the scale 11, and the eyelashes are observed through the support 2 in a transparent manner.

  The density of the eyelash bundle can be measured by counting the number of eyelashes between two consecutive scales 21.

  When measuring the degree of curvature of the eyelashes, the straight edge 4 is aligned in front of the open eye, and the eyelash may be applied substantially in the tangential direction (perpendicular to the eyelid).

  The angle scale 31 can know the direction of the eyelashes away from the eye lid, and the mark 35 is arranged at the base of the eyelashes. The scale 31 covers, for example, an angle range extending from 0 to 180 ° at a pitch of 10 °.

  FIG. 3 shows an orientation of 80.9 °, which is the average degree of curling of the Japanese population.

  The device 1 may also, for example, count the number of eyelashes extending parallel to the radial scale 21, the number of eyelashes intersecting the scale, and possibly the number of scales intersecting the eyelashes. It can also be used to evaluate composition or unity.

  The device 1 can be used in a retail store, for example, by an advisor handling it to evaluate the customer's eyelash type and prescribe the appropriate product for the customer.

  The apparatus 1 is also consumed in a common packaging material 50 such as a box, bag, blister pack, or cosmetic box, as shown in FIG. 4, in combination with a product P for application of eyelashes such as a cosmetic or eyelash care product. Can be proposed.

  The present invention is not limited to the above embodiments. For example, the shape of the support 2 can be changed, or one or two of the measurement scales for eyelashes can be eliminated.

  The expression “comprising” should be understood as synonymous with “including at least one” unless the contrary is indicated.

It is a front view which shows an example of the apparatus by this invention. FIG. 2 shows the use of the apparatus of FIG. 1 to measure the length and density of eyelashes. FIG. 2 shows the use of the apparatus of FIG. 1 to measure the degree of curvature of eyelashes. FIG. 2 shows a set comprising a device according to the invention.
