Cosmetic for reducing wrinkles, containing ginsenosides rg3, rg5, and rk1

The present invention relates to a cosmetic composition for reducing wrinkles, containing ginsenosides Rg3, Rg5, and Rk1 and, more specifically, to a cosmetic composition, which is more effective in reducing wrinkles caused by a stress stimulus due to ultraviolet rays and infrared rays, containing ginsenosides Rg3, Rg5 and Rk1, wherein the number of water-soluble Rg3(S) isomers is greater than the number of oil-soluble Rg3(R) isomers. According to the present invention, at least three times more of water-soluble Rg3(S) isomers can be contained than oil-soluble Rg3(R) isomers since ginsenosides are separated and purified by enzymatic conversion method rather than a normal boiling or simmering method. In addition, the cosmetic composition for reducing wrinkles, containing ginsenosides Rg3, Rg5 and Rk1, of the present invention, inhibits 11β-HSD1, which is a stress hormone related to skin aging caused by photoaging, and MMP-1, which is a matrix proteinase, thereby enabling an effect of preventing or alleviating skin aging to be exhibited.
