This exfoliating toner combines four high quality acids to revitalise the skin, improving its texture and appearance. It's formulated with three AHAs (alpha-hydroxy acids): glycolic acid (5%), lactic acid (0.5%) and mandelic acid (0.5%); and salicylic acid (2%) – also referred to as beta-hydroxy acid, or BHA. The AHAs are water-soluble acids that dissolve the cells on the skin's surface, artificially speeding up cell turnover to reveal the fresh new layers underneath. They're effective in treating hyperpigmentation, dullness, and by stimulating collagen production, it helps fight the signs of skin aging, such as fine lines and wrinkles. Salicylic acid is an oil-soluble acid that penetrates deeper, exfoliating the skin and unclogging pores.
