Intensively refine rough, congested skin with COSRX The AHA BHA PHA LHA 35 Peel. This potent Korean rinse-off treatment combines four types of exfoliating acids at a total 35% concentration to remove dead skin cells, clarify pores and improve the look of uneven texture and dullness. Designed for experienced acid users with oily or blemish-prone skin.

Patch test first. At night, apply a thin even layer to clean, completely dry skin, avoiding eyes, lips and damaged areas. Leave on for no more than 10 minutes, then rinse thoroughly with lukewarm water. Use once weekly. Do not combine with other acids, scrubs, retinoids or strong vitamin C; wear SPF daily.
