It is also suitable for sensitive skin. Key ingredients include Sebulyse, a new sebo-regulating active ingredient more powerful than zinc, selected for its ability to inhibit sebum production at its source. La Roche-Posay Thermal Spring Water, a real wonder of nature with its soothing, antioxidant properties. The oil-free texture is enriched with absorbent micro-spheres and perlite for a matt skin finish on application. Non-comedogenic. Hypoallergenic. Paraben-free. Tested under dermatological control.
