COSMETIC COMPOSITION, CONTAINING PEPTIDE OF ASTRAGALUS MEMBRANACEUS, FOR PREVENTING SKIN AGING

摘要

A cosmetic composition containing a peptide of Astragalus membranaceus, of the present invention, reduces the expression of matrix metalloproteinases (MMPs), increases the synthesis of procollagen in fibroblasts, and ultimately reduces the collagen degradation through the reduced MMPs and the increased procollagen, thereby preventing and alleviating skin aging, and thus can be used as a cosmetic agent for preventing skin aging. In addition, the present invention provides a cosmetic composition, containing a peptide of Astragalus membranaceus, for preventing collagen degeneration.
