SYNERGY Toner is rich in Black Willow Bark which is high in salicylates. Salicylates are effective in exfoliating the skin and produce a clearer skin by getting rid of dead skin cells. It is used because of its lipid solubility and the top layer of skin is rich in lipids. This is a very gentle facial product and contains no alcohol which can be drying to the delicate facial skin. A definite luxury for your skin!
