AHA blend glycolic and citric acids and hexapeptide-9: keep them apart

Keep them apart

Use them at different times of day, applying the acid first and the peptide later, because the acid is too harsh for the peptide. The strong acid breaks down the peptide and stops it from working properly. You can easily fix this by using the acid in the morning and the peptide at night.
