Powered by the brand's not-so-secret ingredient, discovered in the 14th century, La Roche-Posay uses the soothing nature of thermal spring water to reveal simple and efficient solutions for your skin's most sensitive issues. Boasting an invisible finish and non-greasy texture is the Anthelios Oil Control Fluid SPF50+ for Oily Blemish-Prone Skin (50ml), a formula which offers a sun-protective shield against harmful UV rays.
