Ingredient N° 21

Copper Peptides

A distinct peptide family best kept in a simple routine.

Copper peptides such as GHK-Cu are used in products targeting the appearance of firmness and skin recovery. Human cosmetic evidence is still more limited than the marketing suggests, so they are best treated as an optional supportive step.

Worth knowing

Keep the routine simple when introducing them; BUÉE flags same-period use with strong acids as a caution.
