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.

  • Retinol + glycolic acid is a classic barrier-buster. Use on different nights.

  • Retinol + lactic acid is gentler than glycolic but still alternate nights to be safe.

  • Retinol + mandelic acid — alternate nights to preserve barrier integrity.

  • Benzoyl peroxide can break down retinol. Use one in the morning and the other at night, or pick a stabilized formula made to combine them.
