GHK-Cu and skin & hair research

Decades of dermatological literature on the copper-binding tripeptide GHK-Cu — collagen, follicles, and wound-healing studies.

GHK-Cu is one of the most established peptides in dermatological research. The literature stretches back decades, anchored in three areas: collagen, follicles, and wound healing.

Collagen and skin remodeling

In-vitro and animal studies report increases in collagen and elastin synthesis with GHK-Cu exposure, alongside modulation of skin-remodeling gene expression.

Hair-follicle research

Studies have examined GHK-Cu's role in dermal-papilla cell activity and follicle-size measurements, with results that have shaped its inclusion in topical research formulations.
