Bioderma Sebium Anti-Blemish Serum (30ml) is a concentrated corrective serum for oily, acne-prone skin, formulated with Fluidactiv®, salicylic acid, and zinc sulfate to regulate sebum, reduce pore congestion, and prevent imperfections. Its non-greasy texture absorbs quickly, promoting a clearer, matte complexion while calming redness and inflammation. With continued use, the serum helps refine skin texture, control shine, and maintain a balanced, healthier-looking appearance.
