After cleansing, apply this mandelic exfoliating toner to a cotton pad or directly into your hands, then gently pat it onto your face, avoiding the eye area. Use it preferably in the evening, 2 to 4 times a week depending on your skin’s sensitivity, and let it absorb before applying your serum and moisturizer. Don’t forget to apply sunscreen in the morning, as AHAs make the skin more sensitive to UV rays.
