Salicylic Acid 2% Anhydrous is a gentle formula that is designed to exfoliate the skin, decongest pores, smooth textural irregularities, & reduce redness & uneven skin tone. Among our other salicylic acid offerings, what sets this formula apart is its squalane-based emollient base & supporting hydrating polyglycerides. These ingredients release the salicylic acid over time & 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.
