Tretinoin and collagen peptide: keep them apart

Keep them apart

Use them at different times of day, applying collagen peptides in the morning and tretinoin at night. Using them together can cause extra skin irritation because both ingredients work hard at the same time. The shopper can change their routine by using a gentler strength or more time between the two products.
