Exfoliating and cooling toner/essence , COSRX Two in One Poreless Power Liquid is a two-in-one combination: exfoliation and cleansing. The white willow bark extract and gentle BHA acids contained in the composition remove dead skin cells, control sebum production, provide antioxidant protection to the skin and even out its tone. Salicylic acid cleanses and visibly reduces facial pores, while panthenol and allantoin intensively moisturize and soothe the skin. The product is gentle enough to be used with other AHA or BHA products.
