La Roche-Posay Effaclar Purifying Foaming Gel is a gentle, pH-balanced foaming cleanser specifically designed for oily, acne-prone, and sensitive skin, effectively removing excess sebum, impurities, and dirt without stripping or over-drying the skin, while helping to purify, mattify shine, and maintain the skin's natural microbiome balance for clearer, fresher complexion. It features key ingredients including Zinc PCA (Zinc Pidolate) to purify and regulate excess oil production, Phylobioma active (a microbiome-targeted component) to reduce sebum overproduction at the source and limit blemish-causing bacteria like C. acnes phylotype IA1, along with soothing La Roche-Posay Thermal Spring Water for anti-irritant and antioxidant benefits, and mild supporting agents like Citric Acid for gentle pH adjustment.
