Refine the texture of skin that is prone to excessive oiliness with the Bioderma Sebium Pore Refiner, a corrective concentrate. This targeted daily treatment works to tighten pores that are dilated, prevent imperfections, and mattify the skin both immediately and over the long term. Antioxidants boost the skins radiance and protect it from external aggressors. Apply the Sebium Pore Refiner once or twice a day, either alone or beneath your usual moisturizer. Combination skin types should apply to the T zone, while oilier types should apply all over.
