GHK-Cu
A naturally occurring copper-binding tripeptide that stimulates collagen synthesis, skin remodeling, and tissue repair at the genetic level.
GHK-Cu (glycyl-L-histidyl-L-lysine copper complex) is a naturally occurring peptide found in human plasma, saliva, and urine that declines significantly with age. It modulates the expression of over 4,000 human genes, promoting tissue remodeling, anti-inflammatory responses, and stem cell activation. Clinical studies show it outperforms both vitamin C and retinoic acid for collagen stimulation.
⚙️ Mechanism of Action
GHK-Cu delivers bioavailable copper to tissues, activating metalloenzymes essential for collagen and elastin crosslinking. It stimulates dermal fibroblast proliferation, increases collagen I and III synthesis, and promotes glycosaminoglycan production. At the genetic level, it upregulates genes involved in wound healing and tissue remodeling while downregulating inflammatory and tissue-destructive pathways.
✅ Benefits
- •Stimulates collagen production more effectively than vitamin C or retinoic acid
- •Accelerates wound healing and tissue repair
- •Improves skin elasticity, thickness, and hydration
- •Promotes hair growth and follicle health
- •Reduces fine lines and photodamage
- •Anti-inflammatory and antioxidant properties
⚠️ Risks & Considerations
- •Skin irritation at higher concentrations
- •Potential copper overload with extended use
- •Mild redness at injection sites
- •Not recommended for those with Wilson's disease
