Created to hydrate skin while minimizing excess oil and sebum, Mattifying Hydrator helps break the cycle of problem skin.

With a lightweight texture, it quickly absorbs before priming skin for a velvety, flawless finish that is further enhanced by light-diffusing powders to instantly blur the look of pores and imperfections.. Ideal for oily and combination skin. In an instrumental evaluation conducted on 30 volunteers, after 8 hours 100% showed a decrease in excess oil and 97% showed a more hydrated skin. Fragrance-free, hypoallergenic, non-comedogenic & dermatologist-tested. 1.7 oz/ 50 g. Apply a thin layer to cleansed face, AM and/or PM. DRBT-WU33. 100000000275.
