Layering Alpha Hydroxy Acids (AHA) and Beta Hydroxy Acids (BHA) produces an additive exfoliating effect. While sometimes used in clinical peels, at-home layering drastically increases the risk of severe redness and barrier disruption.
Do not layer them in the same step unless they are pre-formulated together in a single product. If using separate products, alternate nights.
Alternate nights (e.g., AHA on Monday, BHA on Tuesday). Do not use both on the same day.
- ☀️Salicylic Acid only if your skin tolerates it.
- ☀️moisturizer and sunscreen.
