What does GHK Copper Peptide Do?
GHK-Cu, or Copper Tripeptide-1, is a natural copper complex of the peptide glycyl-L-histidyl-L-lysine. Roles in the body include promoting wound healing, attracting immune cells, anti-inflammatory and antioxidant.
Copper peptides are a cutting-edge cosmeceutical ingredient that helps reduce wrinkles and fine lines to achieve skin tightening, improves skin elasticity, and improves the appearance of skin by promoting dermal regeneration. It boosts collagen and elastin production for firmer, plumper, smoother skin.
Does GHK-Cu regrow hair?
Copper peptides are not only useful in skin care, but also in promoting scalp health and hair growth. It enlarges hair follicles, promotes hair follicle growth, enhances blood flow to the scalp, stimulates nerve regeneration, and prolongs the growth period of hair to make it thicker.
GHK Cu is effective in preventing hair loss by repairing damaged hair follicles, moisturizing hair follicles, preventing hair thinning and promoting blood circulation.


Zinc-based sunscreen products
Zinc-containing SPF creams should not be mixed with GHK-Cu. It is recommended that the two be used at intervals, and that GHK-Cu not be added to zinc-based sunscreen products.
Vitamin C-based products
Vitamin C competes with GHK-Cu for activity. Avoid adding GHK Cu to vitamin C containing products.
