When Used Together
CautionGlycolic Acid + Salicylic Acid
Using AHA and BHA together at high concentrations risks over-exfoliation and barrier damage.
Alternate use — AHA one day, BHA the next.
CautionLactic Acid + Salicylic Acid
[Class rule] Combining AHA and BHA increases exfoliation beyond what most skin can tolerate.
Use on alternate days or choose one.
