Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to cosmetics and skin quality improving agents. More specifically, at the same time as covering color tone problems such as color unevenness and spots, it is possible to improve morphological problems on the skin surface such as pores and wrinkles, and without glare,
The present invention relates to a cosmetic and a skin quality improver capable of obtaining a natural finish with high transparency.

[0002]

2. Description of the Related Art Make-up cosmetics are used for the main purpose of shaping the skin color and stunning the skin by hiding morphological problems on the skin surface such as pores and wrinkles. Conventionally, titanium oxide or the like, which has a high concealing property, has been used to cover color tone problems such as spots, freckles, and uneven color. The height of the hiding power mainly depends on the refractive index of the substance, but cosmetics containing a substance with a high refractive index are effective for color problems such as spots, freckles, etc., but the finish is white, There is a drawback that it becomes thick and becomes unnatural with no transparency.

[0003] In order to correct the hue of the skin, a pigment of a complementary color is also used. However, in this method, since hue correction based on subtractive color mixture is performed, there is a drawback that brightness and saturation are reduced and the skin becomes dull even though hue correction can be performed. In Japanese Patent Application Laid-Open No. 8-81332, a complementary color or a color gamut in the vicinity of a complementary color is applied to a dark color portion (color tone trouble portion) of the skin caused by nevus of the skin, hemangioma, red face, spots, freckles, and the like. There has been proposed a composition for adjusting flesh color, which comprises a substance having transmission interference light. According to this method, it is possible to improve the color tone trouble without dulling the skin.

However, substances having interference light generally have a high gloss, and when incorporated into cosmetics such that the effect is manifested,
There is a drawback that glare is generated due to the strength of the gloss and an unnatural finish is produced. Further, since the particle shape is flaky or plate-like, the result is that the lightness difference between the skin ridge and the skin groove is further emphasized, and there is a problem that the problem with the unevenness on the skin surface cannot be improved at all.

Japanese Patent Application Laid-Open No. 11-43414 proposes a skin cosmetic comprising a specific powder having a small directionality with respect to the incident angle of an interference color, and a colored iron oxide / titanium oxide sintered pigment. Have been. According to this method, there is a proposal that a cosmetic that can change the hue of the skin while giving a sense of transparency and that does not cause makeup collapse due to sebum can be obtained.

However, the techniques disclosed in the present invention cannot exhibit the cosmetic effects of the present invention, such as the effect of improving skin surface morphological problems such as pores and wrinkles and the insufficient finish.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its object is to cover color tone problems such as color unevenness and spots, and at the same time, to eliminate skin surface morphological problems such as pores and wrinkles. An object of the present invention is to provide a cosmetic and a skin quality improving agent which can be improved, have no glare, and provide a natural finish with high transparency.

[0008]
