MacPeptide™ Copper peptide solution contains the molecule consisting of GHK (Gly-L-His-L-Lys) and Cu and has both hair and skin benefits.  MacPeptide™ Copper stimulates fibrolasts to produce collagen and mucopolysaccharide which leads to tighter, smoother skin reducing fine lines and wrinkles. It promotes the expression of hair growth factor by activating hair follicle tissues which regulates hair growth.  MacPeptide™ Copper also scavenges for free radicals providing UV and anti-inflammatory protection.
