Vitamin A and copper peptide: keep them apart

Keep them apart

Use them at different times of day with copper peptide in the morning and vitamin A at night to prevent skin irritation. Using both strong ingredients at the same time can cause redness and irritation because they are both very active. The shopper can switch to a gentler vitamin A strength or wait longer between applying them.
