Carnosine and citric acid: keep them apart

Keep them apart

Use them at different times of day with citric acid first, because acids break down this firming peptide. Citric acid makes the skin too acidic, which ruins the firming peptide and stops it from working. The shopper can use a gentler acid strength or wait longer between them.
