Purifying Treatment Essence is designed to smooth the surface of the skin and help keep the pores unblocked. It contains White Willow Bark which is a natural form of Salicylic Acid to exfoliate the skin without the irritation that is normally associated with Salicylic products. It helps prevent acne from forming while calming existing breakouts and minimizing stinging and irritation. Niacinamide is a powerful anti inflammatory but also brightens and evens out skin tone. Helps to remove dead skin cells and hydrate the skin.
