Layering conflicts

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

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

  • Tretinoin + glycolic acid causes significant barrier disruption. Never layer.

  • Adapalenemedium

    Adapalene + glycolic acid can over-exfoliate. Alternate nights.

  • Benzoyl peroxide breaks down vitamin C, making both less effective. Use one in the morning and the other at night.
