Anti-aging cosmetic composition containing novel heptapeptide monomer and dimer that promotes collagen synthesis

摘要

The present invention relates to a cosmetic composition for preventing or improving skin aging containing a novel heptapeptide monomer and dimer represented by the following formulas 1 to 4 as an active ingredient, and more particularly, a novel heptapeptide monomer and dimer. It inhibits the expression of MMP-1, an important enzyme that causes skin aging, as an active ingredient, inhibits skin collagen degradation and increases the expression of procollagen, thereby preventing and improving skin aging. It relates to a cosmetic composition for. In particular, the heptapeptide monomers and dimers for preventing and improving skin aging can be added to various cosmetic compositions such as skins, lotions, creams, foundations, essences, gels, packs, foam cleansing or soap forms, and have no skin irritation. Skin stability is also excellent.
