The Anti-Blemish Serum is the essential expert care for combination to oily skin. Ultra-concentrated in anti-blemish biotechnological and botanical active ingredients, its triple action formula acts in depth on all types of lesions: pimples, blackheads, enlarged pores and acne marks. Its high concentration of Gluconolactone (10%), an active ingredient as effective as AHA / BHA but better tolerated by the skin, helps unclog pores and refine skin texture, while stimulating cell renewal.
