AHA/BHA Clarifying Treatment Toner

Category
Exfoliant
Fragrance-free

How to use

After cleansing, apply to a cotton pad or hands and sweep over the face, avoiding the eye area; start 2-3 times per week and build up as tolerated. This is a leave-on exfoliating acid product, so patch-test first and avoid layering with other strong actives if your skin is sensitive. Exfoliating acids increase sun sensitivity: always follow with a broad-spectrum SPF in the morning. Not recommended during pregnancy or for infants without professional guidance.
