This two-in-one, skin-smoothing essence-toner cools the skin, and visibly tightens and reduces the appearance of pores. Salicylic acid (aka beta-hydroxy acid, or BHA) exfoliates deep inside the pores, while tannin tightens them to prevent new blackheads from forming. It's hypoallergenic, and free of parabens, sulphates, phthalates and alcohol.
