Azelaic acid and acetyl hexapeptide-3: keep them apart

Keep them apart

Use them at different times of day by applying azelaic acid in the morning and acetyl hexapeptide-3 at night, because acids break down peptides. Mixing them makes the peptide ingredient less effective on your skin, so you will not see the firming results you want. You can fix this by using your acid in the morning and your peptide at night, or by waiting until the first product is fully absorbed before applying the next one.
