Bioderma Sébium Pore Refiner Cream is a dermatological corrective treatment designed to tighten enlarged pores and improve skin texture for combination to oily skin. Its formula features the exclusive Fluidactiv™ patent, which biologically regulates sebum quality to prevent pores from clogging and reduce the formation of blemishes. Enriched with agaric acid, a natural astringent, it refines the skin's surface and helps preserve its natural radiance. The addition of mattifying powders provides a lasting shine-control effect, making it an excellent primer for a smooth, uniform makeup application.
