A naturally occurring copper peptide discussed in connection with skin, hair, and matrix signaling.

GHK-Cu is a small, naturally occurring peptide that binds copper. It is one of the more studied peptides in cosmetic and skin-science literature.
It is discussed in connection with collagen and extracellular-matrix signaling — the structural scaffolding of skin and connective tissue.
It is a copper-binding tripeptide.
Most studied around skin and matrix signaling.
Cosmetic evidence is stronger than systemic claims.
GHK-Cu is described as influencing genes and signals tied to collagen production and tissue remodeling, and it delivers copper, a cofactor in several repair-related enzymes.
It shows up in skin, hair, and connective-tissue conversations, and topical use is comparatively well represented in the literature. Injectable and systemic claims are less established.
Discussed both topically (skin) and as an injectable in research settings. Topical and systemic use are different questions with different evidence.
