Can you use glycolic acid with salicylic acid?
Both are low-pH actives — combine only carefully. Splitting AM/PM is the safer default.
Why
Both glycolic acid and salicylic acid are formulated at low pH to remain effective. Stacking them increases the cumulative acid load on the skin, which can irritate sensitive types.
How to layer them
Standard split: one AM, one PM. If you want to combine in one routine, apply the more acidic one first, wait 15-30 minutes for skin pH to recover, then the second active, then a barrier moisturiser.
