Copper Tripeptide-1

Also known by the acronym “GHK” for the amino acids that make it up (glycine, histidine and lysine), tripeptide-1 is a synthetic signaling peptide known to work with copper in the skin to visibly repair substances that have begun to deteriorate due to age and sun exposure. It can help “teach” damaged areas how to rebuild so the skin looks and feels smoother and firmer.
