Barrier models
Skin-barrier integrity and hydration endpoints are common early research targets.
Collagen
Type I/III collagen and elastin expression are widely studied endpoints.
Remodeling
Wound-healing and tissue-remodeling models are documented across the literature.
GHK-Cu is a naturally occurring copper-binding tripeptide (Gly-His-Lys) complexed with copper. Levels decline with age. In research it is studied for activating genes tied to collagen and elastin synthesis, antioxidant defense, and tissue remodeling.
A copper peptide your body already makes — just less of it every year. ANTHRO's GHK-Cu 1% serum is formulated to support collagen synthesis, skin repair and visible renewal, backed by decades of dermatological research.
“GHK-Cu is the reference copper peptide for our collagen models. Stability and concentration documentation make formulation planning simple.”

GHK-Cu is the tripeptide pre-complexed with copper(II); GHK is the uncomplexed peptide. The copper complex is the most-studied form for remodeling research.
