According to the medical director at ISAAC, care for oily, acne prone skin is important because though the oil helps reduce the first signs of ageing, it leads to breakouts. Salicylic acid exfoliates and cleans the pores from within. Lactic acid exfoliates and hydrates the skin whereas Azelaic acid helps to reduce post-acne erythema. Dimethicone imitates oils and clays like Kaolin and bentonite leave the skin feeling healthy yet matte. Creams containing myrtacine and niacinamide help prevent active breakouts.
