2. Description of the Related Art Recently, the problems to be solved by the invention
Effective in removing wrinkles or stains on the skin, for example, α
Cosmetics containing low levels of chemical peeling agents such as hydroxyside (AHA) have been used extensively. Removal of wrinkles and stains is considered as one of the medical treatment methods in Europe and the United States, and peeling agents such as trichloroacetic acid (TCA), phenol, and α-hydroxyacid (AHA) are used as aqueous solutions of various concentrations for an appropriate time. The method of treating by applying it to the skin and creating a chemical burn (corrosion) is generally performed in Western dermatology, plastic surgery, and cosmetic surgery. It is also practiced to apply a drug such as hydroquinone to the skin as a whitening agent to reduce the melanin pigment of the skin. As described above, the chemical peeling agent is an agent that acts on an affected area of wrinkled or spotted skin to corrode the skin of the area, and then regenerates normal cells, and the whitening agent is a skin by a pharmacological action. It suppresses or reduces the production of the melanin pigment of.

However, in the conventional method of applying the above-described peeling agent aqueous solution to the skin, a liquid peeling agent is applied between the peeling agent having a certain concentration applied to the skin, the action for a few seconds to a few minutes, and the rinse. It was extremely difficult to control and control the depth of corroded skin, and the depth of penetration of the peeling agent into the skin could not be controlled. By conventional methods, the peeling agent does not penetrate too deeply into the skin (so that it does not cause the common complications of scarring, pigmentation and depigmentation), and it does not affect the skin of the affected area. It is a technique requiring skill to make the chemical peeling agent act uniformly.

In particular, the skin of Asians and Africans, including Japanese, is more susceptible to scarring than whites and is more prone to pigmentation and depigmentation, so that the chemicals are in great demand even though they are in high demand. It is considered unsuitable for peeling,
The current situation is that almost nothing is done. In addition, as a problem when treating with a whitening agent, the whitening agent acts not only on the pigment of the spots but also on the pigment of the clean skin to lighten the skin color, so it can be used as a general method. When applying a cream or solution containing a whitening agent only to the spots, the drug inevitably spreads around the spots, so both the spots and the healthy part around them are colored together. Sometimes it was thinned and the effect was not clear, and the area around the spot became lighter than the normal skin color and became a two-tone spot surrounded by a white ring. Also, the whitening agent applied was easy to remove, so it was difficult to obtain lasting effects. Therefore, the present inventor, when using the whitening agent for the purpose of treating spots, the whitening agent does not spread to the normal skin part around the spot, and the whitening agent stain removing tape that can maintain a constant concentration for a long time solves those problems. It came to a solution.

[0005]

Therefore, the inventor of the present invention
As a result of various studies so that the peeling agent or the whitening agent always acts uniformly on the skin in a limited area, and the depth at which it acts can be adjusted, an adhesive containing the peeling agent was applied to the base cloth, The present invention has been completed by finding that the object can be achieved by applying a cloth to a portion to be treated, and the object of the present invention is to provide fine wrinkles and stains (pigmentation, senile pigment spots, etc.) on the skin. The purpose of the present invention is to provide a peeling agent or a tape containing a peeling agent or a tape containing the peeling agent, wherein the peeling agent or the tape can be adjusted uniformly on the skin for the purpose of whitening the skin or for whitening the skin by the application time.

SUMMARY OF THE INVENTION The gist of the present invention is a grid pattern.
A cosmetic tape having an adhesive layer containing a chemical peeling agent or a whitening agent on a base cloth having holes in the
The pressure-sensitive adhesive layer has a pressure-sensitive adhesive at a position corresponding to the position of the holes of the base cloth.
The cosmetic tape is characterized by having pores that do not exist . That is, in the present invention, the chemical peeling agent or whitening agent is applied to the affected area of the skin is mixed into the adhesive, by using a base fabric having a hole the pressure-sensitive adhesive in a grid pattern, the base
Holes without chemical peeling or whitening agents on the cloth
Is a cosmetic tape applied so that it exists in a grid pattern, and by sticking this tape to the affected area, the skin is corroded and chemically scraped, or the melanin pigment is reduced, and It is a light-colored product, which is more localized and has a slower and more uniform penetration into the skin than when an aqueous solution of a drug is applied to the skin. The depth can be adjusted, and the depth and degree of skin corrosion can be adjusted by controlling the concentration of the chemical peeling agent mixed in the adhesive. Of course, it is possible to treat wrinkles and stains more safely for Asians as well.

Next, the present invention will be described in more detail. The base fabric used in the present invention is a woven fabric or a non-woven fabric, a polyurethane-based synthetic resin sheet, a polyethylene-based synthetic resin sheet, a polyester-based synthetic resin sheet or a sheet made of a paper material, rubber, etc. It is not different from the material of the base fabric that is used. These base fabrics
Those that have holes in a grid pattern and have elasticity
Preferred . In particular, those wrinkle base fabric with a high concentration of peeling agents having a hole in shape rated child by the reason described below
Is .

The chemical peeling agent used in the present invention may be any conventionally used one, and examples thereof include α-hydroxyacid (AHA), trichloroacetic acid (TCA), and phenol. The whitening agents used in the present invention include hydroquinone, kojic acid, arbutin and the like. As an adhesive,
A pressure-sensitive adhesive such as a rubber-based pressure-sensitive adhesive or an acrylic pressure-sensitive adhesive, in which a chemical peeling agent is contained. The content of the chemical peeling agent varies depending on the affected area to be applied, but it is usually contained in the adhesive in the range of 1 to 80%, preferably 5 to 70%, and in the case of the whitening agent, 0.01 to 20%. %. In the present invention, various agents can be mixed in the pressure-sensitive adhesive depending on the purpose. That is, for example, a drug having a whitening effect such as hydroquinone and vitamin C preparation, licorice extract, kojic acid, placenta extract, arbutin preparation, and the like, 4-isopropyle, catechol and its derivatives, freckles, retinoid preparation, SH preparation and the like are included. Let

In the present invention, as the base cloth to which the pressure-sensitive adhesive containing the peeling agent for small wrinkles is applied, particularly when used as a base cloth containing a high concentration of the peeling agent, fine pores or It is preferable to provide the holes in a grid pattern. The reason is that the deeper the corrosion of the skin surface due to the chemical peeling agent, the higher the chemical peeling effect, but on the other hand, the deep skin corrosion leads to the damage of the entire epidermis reaching the basal cell layer, so that the skin is regenerated. Was delayed, resulting in scarring, pigmentation and depigmentation on the regenerated skin. Therefore, in order to solve this problem, by providing fine holes or lattice-like holes in the base cloth or the adhesive layer, there is no chemical peeling agent in this portion, and therefore the chemical peeling agent does not act. It is possible to leave even minute parts of normal skin evenly in an island shape, and uncorroded parts will remain in spots in corroded skin, and even if deeply corroded, it will regenerate from the skin remaining in spots, so it will corrode. Fast healing from the skin, scars and pigmentation,
It can make depigment less likely to come. Although the size of the pores varies depending on the peeling agent used and the concentration thereof, it is usually about 0.5 mm square, and an example thereof is shown in FIG. In FIG. 1, the white portion is the hole portion. Instead of providing fine holes in the base cloth, attach an auxiliary tape with holes in the adhesive layer or with ordinary tape to the treatment site, and then use the tape containing the chemical peeling agent on it. However, the same effect can be obtained,
By adjusting the size and density of the holes of this auxiliary tape, the degree of delicate peeling can be adjusted. These are also one embodiment of the present invention.

EXAMPLES Next, the present invention will be described more specifically with reference to examples. The adhesive polyvinyl alcohol gel was immersed in Example 1 50% TCA, and the outer corner of the eye to chemical peeling tape created with a coating weight of 100 mg / cm ² to the base fabric of a polyester film having a grid pattern holes shown in FIG. 1 When it is applied around the lips for a certain period of time, it corrodes the skin of the part,
After about 3 to 4 weeks, fine wrinkles were removed and the skin became good. Example 2 40 mg / cm of an adhesive obtained by mixing 5 parts by weight of hydroquinone with 100 parts by weight of a rubber-based adhesive was applied to a base fabric made of a non-woven fabric.
^When the stain-removing tape prepared with the application amount of ² was adhered to the pigmented portions such as the cheek and the temporal region for 4 months, the stains on the portions became thin so that they were hardly noticeable.

[0011]

INDUSTRIAL APPLICABILITY According to the present invention, a chemical peeling agent is added to a pressure-sensitive adhesive to form a peeling tape which is applied to a tape, thereby making it more permeable to the skin than when an aqueous solution drug is applied to the skin. Since it acts slowly, locally and uniformly, the depth and degree of skin corrosion should be controlled by controlling the concentration of the chemical peeling agent mixed in the adhesive, the application time, and the size and density of pores. Can be done. Further, as in the present invention, the same effect as that of the ODT therapy (occlusive bandage therapy) of the drug can be expected by adding a low concentration drug to wrap the affected area of the skin as a tape.
