The present invention relates to a composition comprising as an active ingredient a processed extract of the genus Panax plants having a sum of the contents of ginsenosides Rg3, Rg5, and Rk1 higher than the sum of the contents of ginsenosides Rb1, Rb2, Rc, and Rd, More specifically, increased cell proliferation directly in the deramal fibroblast, increased collagen and TIMP-1 synthesis, increased procollagen expression of cutaneous dermal cells due to UV irradiation, and decreased expression of MMP-1 to promote collagen degradation. It can be usefully used as a food additive for improving skin wrinkles by controlling factors related to the generation and degradation of collagen. |
