Glycolic acid and carnosine: keep them apart

Keep them apart

Use them at different times of day, applying glycolic acid first and carnosine later, because acids break down this peptide. Glycolic acid can neutralize carnosine, making it much less effective for your skin. To fix this, you can use a gentler acid or wait longer between applying them.
