La Roche-Posay Effaclar Mat is a specialized moisturizer designed for oily and combination skin types. This sebo-controlling formula helps regulate excess oil production, minimize the appearance of enlarged pores, and provide a long-lasting matte finish while keeping skin hydrated. The formula contains Sebulyse technology which provides superior oil control compared to traditional zinc-based products. It also features microsponges to absorb excess sebum and La Roche-Posay Thermal Spring Water for hydration. The non-comedogenic formula is suitable for sensitive skin and can be used as a makeup base. For best results, apply morning and/or evening after cleansing, avoiding the eye area. The product remains effective for 12 months after opening.
