Eucerin DermoPURIFYER Scrub is to be used  weekly as part of a cleanse, clear and care routine. Its oil-free formula, with Lactic Acid, works directly where blemishes originate without drying out the skin. Pore-refining micro-particles gently exfoliate the skin without damaging it. Skin is noticeably clearer, smoother and visibly refined as a result.
