GHK-Cu (also called Copper Tripeptide-1) is a naturally occurring molecule made of a small peptide—glycine, histidine, and lysine (GHK)—bound to a copper ion (Cu²⁺). It was first identified in human plasma and is also found in saliva and urine.
Why is it popular?
GHK-Cu is best known for its potential roles in:
- Skin repair and wound healing
- Collagen and elastin production
- Reducing signs of skin aging (fine lines, wrinkles, skin texture)
- Hair growth and scalp health
- Anti-inflammatory and antioxidant effects
How is it used?
Most commonly, GHK-Cu is found in:
- Skincare serums and creams
- Hair/scalp products
- Cosmetic formulations marketed for anti-aging and skin rejuvenation
Topical use in cosmetics is common and generally considered low-risk.
What does the science say?
There is decent evidence that GHK-Cu can stimulate processes involved in tissue repair and collagen production. However, many broader claims circulating online (longevity, systemic healing, dramatic regeneration, etc.) are based on laboratory, animal, or preliminary studies rather than large, definitive human clinical trials.
What about injections?
You’ll often see GHK-Cu discussed in peptide and biohacking communities as an injectable peptide. It’s important to know that:
- Injectable GHK-Cu is not FDA-approved as a drug.
- Safety and efficacy data for injection are much more limited than for topical cosmetic use.
In one sentence
GHK-Cu is a naturally occurring copper peptide that has become popular in skincare because it may support collagen production, wound healing, and skin repair, though some of the more ambitious health claims remain unproven.
