Collagen is the core structural protein that maintains the youth and health of tissues such as skin, bones, and tendons. Among them, Type I collagen accounts for about 90% of the total collagen in the human body and is the key cornerstone supporting skin elasticity and strength. However, with age and environmental influences, the human body's ability to synthesize collagen gradually declines, leading to skin sagging and the formation of fine lines. Beauty and skincare products based on Type I collagen are suitable for areas such as the face, around the eyes, and the neck, and can improve the skin barrier, inhibit tyrosinase, and reduce melanin deposition. Traditional animal-derived collagen has limitations such as viral risks, immune rejection, and structural differences. This product is expressed and purified from yeast using genetic recombination technology and is provided in lyophilized powder form. Recombinant humanized collagen, due to its excellent physical properties and biological characteristics, has extensive applications in the fields of biomedicine and cosmetics.
