Copper Peptides FAQs

Copper peptides signal your skin to make collagen and repair damage. Skin looks firmer and smoother after about 8 to 12 weeks.

Use them at different times of day. Strong vitamin C and acids can break the bond between the copper and the peptide.

You can use them once or twice a day. They are gentle and rarely irritate.

Early studies suggest GHK-Cu supports the hair follicle, and it is used in scalp serums. The research is still small.
