What is GHK-Cu?
GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) found in human plasma, saliva, and urine. It has a high affinity for copper ions, forming the GHK-Cu complex. Discovered in 1973, GHK-Cu is a powerful regenerator of skin and connective tissue, widely integrated into high-end anti-aging skincare and hair restoration formulations.
How does GHK-Cu work?
GHK-Cu works by regulating a vast array of genes involved in tissue remodeling and wound healing. It stimulates the synthesis of collagen, elastin, and glycosaminoglycans (like hyaluronic acid) in fibroblasts. It also acts as a potent antioxidant, suppressing inflammatory cytokines (like TNF-alpha and IL-1) and neutralizing free radicals. Furthermore, it promotes angiogenesis and supports hair follicle health by increasing follicle size.
Primary Documented Uses
- Reducing skin wrinkles, fine lines, and signs of photoaging
- Improving skin firmness, elasticity, and barrier function
- Stimulating hair follicle growth and treating thinning hair
- Accelerating wound healing and reducing scar tissue formation
Research Summary
Dermatological clinical trials consistently show that topical application of GHK-Cu improves skin elasticity, reduces fine lines and wrinkles, increases skin density, and evens out hyperpigmentation. In wound healing research, it accelerates the closure of diabetic ulcers. In hair restoration studies, it demonstrates efficacy comparable to minoxidil in promoting follicle growth.
Legal and Regulatory Status
GHK-Cu is legally and widely available as an ingredient in cosmetic products. It is approved for use in topical skincare and hair formulations. Injectable forms of GHK-Cu, while studied in research, are not FDA-approved for human injection, and compounding of injectable GHK-Cu is restricted.
