Salicylic Acid 2% Anhydrous is a gentle formula that is designed to exfoliate the skin, decongest pores, smooth textural irregularities, and reduce redness and uneven skin tone. Among our other salicylic acid offerings, what sets this formula apart is its squalane-based emollient base and supporting hydrating polyglycerides. These ingredients release the salicylic acid over time and result in a more balanced distribution that helps reduce the irritation potential that can be associated with acid use making it ideal for new users.
