Description

[Technical field]

[0001] The present invention relates to a method for measuring the volume of the back of a hand of a human, for example. [Background technology]

[0002] Human skin is a complex organ that covers the entire body. There are different types of skin in different parts of the body. For example, the skin on the face is different from the scalp, and even the skin on the front of the hand (palm) is different from the skin on the back of the hand. Although the types of skin vary depending on the location of the human body, skin is usually composed of two main layers of tissue: the outermost layer, the epidermis or cuticle, which is the superficial layer (from the outside, the stratum corneum, the stratum lucidum, and the stratum granulosum) and the deep layer (stratum spinosum and stratum basale). The dermis, cutis vera, or true skin, is composed of an upper papillary layer and a lower reticular layer (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication 2010-195817 Summary of the Invention [Problem to be solved by the invention]

[0004] The problem to be solved by the present invention is to provide a novel method for more easily measuring the volume of the back of a human hand, etc. [Means for solving the problem]

[0005] Therefore, the inventors of the present invention have conducted extensive research and have completed the present invention by utilizing, for example, face-specific analysis software.

[0006] The present invention includes the following items. [Item 1] A method for evaluating the volume of the back of the hand, comprising the steps of: applying the composition to the back of the hand; taking an image of the back of the hand after the applying step; A process of measuring the volume of the back of the hand using analysis software (e.g., analysis software specifically for the face). Effect of the Invention

[0007] It is possible to provide a novel method for more easily measuring the volume of the back of a human hand in the cosmetic field and the like. [Brief description of the drawings]

[0008] [Figure 1] FIG. 1 is a diagram showing an outline of a monitoring test using the method of the present invention described in Example 1. [Diagram 2] 1 is a photograph showing the results of Example 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described.

[0010] (Volume of the back of the hand) The back of the hand is a part that is easily exposed to stimuli such as ultraviolet rays, the outside air, and water. These stimuli can cause the back of the hand to thin and become muscular, and the veins can become clearly visible. To maintain this volume, the back of the hand needs to be plump to a certain extent.

[0011] (Face analysis software) Examples of face analysis software include VISIA (registered trademark) and VECTRA Handy H1 (registered trademark, CANFIELD). In the following examples, VECTRA Handy H1 was used as the face analysis software.

[0012] (Image capture) The image is captured by an imaging device such as a digital camera so that at least one reference point and one measurement point are included. An image is acquired by imaging, and changes in the shape, area, and other aspects of the skin surface contained in the image are grasped. The image may be, for example, a still image or a video.

[0013] (Form of composition) The compositions used in the tests using the method of the present invention (such as compositions for external application to the skin) are in suitable forms for use, such as ampoules, capsules, powders, granules, liquids, gels, foams, emulsions, sheets, mists, sprays, etc., and include 1) pharmaceuticals, 2) quasi-drugs, and 3) topical or whole-body skin preparations (for example, basic cosmetics such as lotions, milky lotions, creams, ointments, lotions, oils, and packs, face washes and skin cleansers such as solid soaps, liquid soaps, and hand washes, massage preparations, cleansing preparations, hair removal preparations, depilatories, shaving treatments, aftershave lotions, pre-shave lotions, shaving creams, foundations, lipsticks, blushers, Make-up cosmetics such as eye shadow, eyeliner, mascara, perfumes, nail beautifying products, nail beautifying enamel, nail beautifying enamel remover, poultices, plasters, tapes, sheets, patches, aerosols, etc.); 4) medicinal and / or cosmetic preparations applied to the scalp and hair (for example, shampoos, rinses, hair treatments, pre-hair treatments, permanent solutions, hair dyes, hair styling products, hair tonics, hair growth and tonic products, poultices, plasters, tapes, sheets, aerosols, etc.); 5) bath products used by adding them to the bath; 6) other products such as underarm odor prevention agents, deodorants, antiperspirants, sanitary products, sanitary cotton, wet tissues, etc.

[0014] The present invention will now be described in more detail with reference to examples, but the present invention is not limited to these examples in any way. EXAMPLES

[0015] The following examples of the present invention will be described. The following experimental materials were used in the experiments described in the examples.

[0016] [Example 1]

[0017] A roughly life-size face model was created (Figure 1 (1)). However, the nose was made removable. As shown in Figure 1 (1), the middle finger was placed at the center and the wrist was not protruding from the face. The hand was placed on the model from a stand adjusted to the same height as the model and the hand, and the nose was placed on the middle finger (Figure 1 (1)). Using a VECTRA Handy, images were taken in three directions (front, left, and right) from a certain angle and distance, and the facial images were synthesized in 3D using dedicated automatic analysis software.

[0018] Image A (before application of the composition to be measured) and image B (after application of the composition to be measured) created by this synthesis were selected and aligned, and the areas where volume had changed in the two images were displayed color-coded with contour lines (Figure 1 (2)). The presence of the nose made it possible to align the two images, and the areas of change could be displayed. When the area of ​​the back of the hand that was to be quantified was selected, the volume (cc) was displayed (Figure 1 (3), shown as 8.60cc in Figure 2). The volume change after treatment for each subject's image could be calculated and compared.

[0019] The above describes the embodiment of the present invention (including examples) with reference to the drawings. However, the specific configuration of the present invention is not limited to this, and even if there are design changes, etc., within the scope that does not deviate from the gist of the present invention, they are included in the present invention. [Industrial Applicability]

[0020] The present invention is utilized as a novel method capable of easily measuring the volume of the back of a human hand in the cosmetic field and the like.
