Can You Use Peptides With AHA?
Separate or space out
With care.
Most peptides are unstable at the low pH an AHA creates, so the acid can cleave them before they reach the skin. This wastes the peptide rather than harming you.
How to use Peptides and AHA
Acids in the evening, peptides in the morning, or wait 30 minutes between layers.
General guidance from common dermatological advice, not medical advice. If you use a prescription treatment, follow your prescriber’s instructions.
