The Eucerin DermoPurifyer Protective Fluid SPF30 is a lightweight, mattifying sunscreen for acne-prone skin that prevents post-acne marks from darkening, controls shine, and soothes inflammation, featuring Licochalcone A, Decanediol, and SPF30 UV filters for antibacterial, anti-inflammatory, and sun protection. It’s non-comedogenic, absorbs quickly, and offers a dry matte finish, ideal for daily use with other DermoPurifyer products, especially the Triple Effect Serum, for comprehensive blemish care.
