5 peptides. The 500-dalton peptide is a small molecule peptide with an average of 5 peptides. There is almost no absorption barrier in the absorption of human epidermal cells, which can move freely between cells, forming a unique absorption mechanism, directly absorbing without digestion, and entering the skin basement in a complete form. As a typical small peptide, 500 dalton peptide is an ultra-low molecular weight oligopeptide, which is generally composed of 2-4 amino acids. High activity, and can be used in medicine, beauty and other industries to repair and cure cell nuclei.
