Abstract

PURPOSE:To obtain a beautifying cosmetic having excellently improving effects on skin pigmentation, capable of treating and moderating pigmented skin to return to a normal color of skin by locally applying the cosmetic to stain, freckle and pigmentation part after suntan. CONSTITUTION:The objective cosmetic contains 0.01-50wt.%, preferably 0.1-20wt.% p-hydroxycinnamic acid of the formula (at least one of R1 and R2 is lower alkyl and the rest is H; R3 is H or lower alkyl) such as p-hydroxy-beta- methylcinnamic acid ethyl ester as an active ingredient. A dose is preferably 1-20mg based on 1cm<2> skin surface in the case of cream of ointment state and 1-10mg in the case of liquid preparation. The compound, for example, is obtained by condensing p-hydroxygenzaldehyde with an alkylmalonic acid in the presence of a base such as pyridine or piperidine and optionally esterifying.

2. Description of the Related Art Stain, freckles and pigmentation after sunburn are less likely to occur, increase or disappear with ageing, which is a problem for the skin of middle-aged and older people. Although the mechanism of the onset of these pigmentation disorders has not been clarified yet, it is considered that the melanin synthesis function in epidermal melanocytes is enhanced by the action of sunlight, particularly ultraviolet rays, and melanocyte-stimulating hormone. In addition, delayed keratinization with aging of epidermal keratinocytes (keratinocytes) also delays the rate of excretion outside the epidermis, and together with the enhancement of melanin synthesis ability,
It is considered that an increase in melanin granule density in the epidermis, that is, a symptom of clinically increasing pigmentation is manifested. Furthermore, because these pigmented areas are locally present and are clearly different from the surrounding normal skin color, the result is that the mechanism that controls the local melanin synthesis enhancement of melanocytes or the melanin synthesis of melanocytes is modulated. You might also say that.

Test Example 2 A brown guinea pig having an acquired ability to form melanin pigment spots was used as an experimental animal, and after pigmentation was formed, the effect of improving fading on pigmentation was examined. Test method: Using a brown guinea pig (a guinea pig whose skin color is similar to that of a human race of yellow color, pigmented spots start to appear about 4 days after irradiation of ultraviolet rays like humans, and turn black most in about 8 days).
The back hair of the guinea pig was shaved with a hair clipper and then shaved with an electric razor. After 8-methoxypsoralen (PUVA) was intraperitoneally administered to this guinea pig, UVA (BLB lamp, 3.1 m
W / cm 2 ) was irradiated for 5 minutes. PUV generated from 15 days after irradiation

The degree of blackening of the skin color was visually evaluated according to the following criteria, and the evaluation points were averaged to measure the effect. The results are shown in Table 2. Criteria 0: No pigmentation is observed. 1: A slight pigmentation with unclear boundaries is observed. 2: Medium pigmentation with clear boundaries is recognized. 3: Clearly marked strong pigmentation is observed. result:
