This formula is for experienced users of acid exfoliation. Cleanse face and wait for skin to dry completely. Using fingertips, apply a thin, even layer to the face and neck, avoiding the eye area. Leave on for no more than 10 minutes. Rinse thoroughly with lukewarm water. Use once or twice a week, ideally in the evening. Always apply a broad-spectrum sunscreen the following day, as this product may increase skin's sensitivity to the sun.
