Collagen peptide and theanine: work well together

Work well together

Use them together in the same routine, applying theanine first and collagen peptide right after. Theanine helps hydrate and prepare the skin so the collagen peptide can work better to firm and smooth. If your skin feels sensitive, use a lower concentration or space the applications further apart.
