Layering conflicts

Ingredients in this product that can react with common actives. Avoid stacking unless noted.

  • Retinol + salicylic acid can over-exfoliate and damage the barrier. Alternate nights.

  • Tretinoin + salicylic acid — major irritation risk. Strict separation required.

  • AHA + BHA stacking risks over-exfoliation. Use a pre-formulated AHA/BHA product or alternate days.
