Regulatory Info
What to Avoid Mixing With
Retinoids and BHA (salicylic acid) together can overdry skin and damage the moisture barrier. Use on alternate nights instead.
Using AHA and BHA together is aggressive exfoliation that can strip the skin barrier. Use on alternate nights for best results.
General guidance
BHA can increase sun sensitivity. Make sure SPF is in your morning routine.
Vitamin C and BHA together may be too acidic. If your skin tolerates it, it's fine. Otherwise, separate into AM/PM.
Peptides
BHA's acidic pH may reduce peptide effectiveness. Consider using in separate routines (acids AM, peptides PM).
Growth Factors
BHA's low pH may reduce growth factor effectiveness. Consider using in separate routines for best results.
Benzoyl peroxide and BHA both target acne but together can be very drying. Consider alternating AM and PM.
Azelaic acid and BHA together may be too drying for some skin types. Monitor for tightness and scale back if needed.
Niacinamide + salicylic acid is a power duo for oily and acne-prone skin. Niacinamide calms any irritation from the BHA.
Unlike retinol, bakuchiol is pH-stable and safe to combine with BHA (salicylic acid). No need to separate them the way you would with retinol.
