Formulated with breakout-prone and congested skin in mind, this liquid toner works hard to unclog pores and regulate oiliness. Powered by a unique complex of encapsulated salicylic acid (BHA) and polylysine, The Control Acid helps to regulate oil production, targeting the root cause of congestion and controlling it before it occurs. Blended with a range of skin-conditioning ingredients, The Control Acid is so much more than a standard BHA. With redness-reducing and barrier-supporting benefits, The Control Acid works to soothe and strengthen the skin whilst simultaneously unclogging pores, leaving skin smoother, clearer and more radiant.
