The hydrolyzed collagen is called collagen peptide. The collagen peptide with molecular weight below 2KD can penetrate into the skin, and has many physiological activities such as antioxidation, cell growth promotion and antibacterial.
Collagen peptide has good water absorption and water retention, and 0.0 1% pure solution of collagen peptide can form a good water retention layer and supply all the water needed by skin. Collagen peptide can also stimulate the growth of fibroblasts, improve the mechanical strength of skin, increase flexibility and help to slow down wrinkles.
