GHK-Cu
Copper tripeptide studied in skin research and cosmetics — not an FDA-approved drug.
What it's for
GHK-Cu is a small natural-style peptide (three amino acids) that binds copper. It shows up in skin biology research and in many cosmetic formulas aimed at how skin looks and recovers.
What it does for the body
In cosmetics and skin research it is discussed for repair appearance, tone, and remodeling signals. It is not FDA-approved to diagnose, treat, cure, or prevent disease. People often hear about it through clinics, forums, or news — this guide sticks to what published research and regulators actually support.
What it targets
In skin-cell models it can gently adjust gene activity tied to remodeling, antioxidant defenses, and matrix support (the collagen-like scaffolding around cells). Think skincare signaling — more like coaching skin-building cells than a prescription disease therapy.
Research context
Bottom line for readers: GHK-Cu is best treated as a research-interest topic. Early papers can be fascinating; they are not a green light for self-experimentation.
