Synopsis A multitude of factors, including excess sebum, stress, tobacco use, and pollution, can cause the pores to dilate and deform. Sébium Pore Refiner is a product of BIODERMA research's innovative skin biology expertise. The skin looks better after using this corrector concentrate; the pores are tightened and become less noticeable, and the skin's grain is finer, more regular, and clearer. The unique, patented Fluidactiv complex keeps the sebum in good condition, preventing pore blockage. Antioxidants protect the skin's natural radiance. Sébium Pore Refiner's light and fluid formula melts quickly and leaves a pleasing velvety finish. Useful hints Apply Sébium Pore Refiner once or twice a day, either all over or on the T zone (chin, nose, forehead) for combination skin, either before or after your skin care cream.
