Can you use glycolic acid with lactic acid?
Pick one per routine. Layering two separate AHAs (glycolic acid and lactic acid) over-exfoliates for most skin types.
Why
Both glycolic acid and lactic acid dissolve corneodesmosomes (the bonds between dead skin cells). Stacking them in one routine doubles the exfoliation load on the same recovery cycle.
How to layer them
Use one or the other per evening. If you want the benefits of both, alternate nights — glycolic acid Mon/Wed/Fri, lactic acid Tue/Thu/Sat, Sunday off. Combined-acid products (Paula's Choice 25% AHA + 2% BHA peel) handle this safely because the formulator balances pH.
