Betaine and copper peptide: work well together

Work well together

Use them together by applying the hydrating betaine serum first, followed by the copper peptide product, for better absorption. Betaine draws in moisture to help the copper peptides work better on your skin. You can use a gentler hydrating product or wait a little longer between steps if your skin feels sensitive.
