Copper peptide naturally found in human plasma — one of the most researched skin and wound healing peptides.
Chelates copper ions and delivers them to cells. Stimulates collagen, elastin, and glycosaminoglycan synthesis. Activates antioxidant enzymes, promotes angiogenesis, and has anti-inflammatory and remodeling effects on skin.
Naturally occurring tripeptide (Gly-His-Lys) found in human plasma, saliva, and urine. Levels decline significantly with age from ~200ng/mL in young adults to ~80ng/mL in elderly. This decline may contribute to reduced healing capacity.
Extensively researched for both cosmetic and wound healing applications. Also under investigation for lung tissue regeneration in COPD. One of the few peptides with robust human clinical data for skin applications.
