The beauty function of collagen;

The chemical composition and structure of collagen give it a beautiful foundation. Collagen is similar to human skin collagen in structure, and it is a kind of water-insoluble fibrous sugar-containing protein. Its molecules are rich in amino acids and hydrophilic groups, and have certain surface activity and good compatibility. At the same time, because its molecules contain a large number of hydroxyl groups, it has a quite good moisturizing effect. When the relative humidity is 70%, it can still keep 45% of its own weight of water. Experiments show that 0.0 1% collagen pure liquid can form a good water-retaining layer and supply all the water needed by the skin.

When collagen is used as an active substance in cosmetics, the latter can diffuse into the deep skin, and its tyrosine competes with tyrosine in the skin and combines with the catalytic center of tyrosinase, thus inhibiting the production of melanin, enhancing the activity of collagen in the skin, maintaining the integrity of moisture and fiber structure in the stratum corneum, promoting the metabolism of skin tissue, and having good moisturizing, anti-wrinkle and beauty effects on the skin. As early as the early 1970s, the United States took the lead in introducing bovine collagen for injection to remove spots, wrinkles and scars. ?
