GHK-Cu is a naturally occurring copper-binding tripeptide found in human plasma, saliva, and urine. It functions as a signaling molecule that resets gene expression to a healthier state, upregulating genes involved in antioxidant defense, DNA repair, and tissue remodeling while downregulating inflammatory and tissue-destructive genes. It stimulates collagen synthesis, glycosaminoglycan production, and angiogenesis. The copper ion is essential for activating copper-dependent enzymes like lysyl oxidase (collagen cross-linking) and superoxide dismutase.

Matrixyl is a lipopeptide consisting of the pentapeptide KTTKS conjugated to a palmitic acid chain. The KTTKS sequence mimics a fragment of type I procollagen propeptide, acting as a matrikine that signals fibroblasts to synthesize new collagen (types I, III, and IV), fibronectin, elastin, and glycosaminoglycans. The palmitoyl chain enhances skin penetration through the lipid-rich stratum corneum. By stimulating extracellular matrix production, Matrixyl reverses visible signs of photoaging and wrinkle formation.

SNAP-8 is an anti-wrinkle octapeptide that functions by inhibiting the SNARE complex assembly required for neurotransmitter release at the neuromuscular junction. It competes with SNAP-25 (a key SNARE protein) for incorporation into the SNARE complex, reducing acetylcholine release and thereby diminishing muscle contraction intensity. This reduces the depth and appearance of expression lines (similar mechanism to botulinum toxin but through competitive inhibition rather than proteolysis). SNAP-8 is an elongated version of Argireline (hexapeptide) with two additional amino acids for enhanced efficacy.
