AcneFree Drying Lotion is specifically formulated in an unique 2-phase solution: 1) The clear liquid contains the acne-fighting ingredient, salicylic acid, which penetrates pores to unclog them. 2) The pink sediment features soothing calamine along with other quick-drying ingredients. The calamine soothes the affected area and acts as a dry, protective barrier overnight. AcneFree Drying Lotion is packed full of specialty ingredients that have anti-microbial and anti-inflammation properties. This product is a great alternative for anyone with sensitivities to spot treatments containing benzoyl peroxide. Compare to Mario Badescu Drying Lotion, this product is a steal!
