US 7,094,407 B2 · Fusion peptide containing human type-1 collagen derived peptide, preparation thereof, and skin anti-aging cosmetic composition comprising the same

Abstract

The present invention relates to a fusion peptide, in which a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human Type-I collagen C-terminal derived peptide, a preparation thereof, and a skin anti-aging cosmetic composition comprising the same. Since the fusion peptide, in which the Tat peptide is bound to the human Type-collagen C-terminal derived peptide is highly stable and has a superior skin absorption capability, the present invention provides a skin anti-aging agent having superior synthesis of collagen and hyaluronic acid, anti-aging effects, and improved durability of the effects.
