The Bioré Clear & Bright AHA Clay Face Mask (£7) works in two ways to leave your skin smoother, your complexion brighter, and your pores a bit clearer. The mask contains clay, which helps absorb excess oil on the surface of the skin, while alpha-hydroxy acids derived from fruits (in this case lemon and papaya) help to remove dead skin cells lingering on the skin that can make your skin look dull.
