CETAPHIL Sheer Mineral Sunscreen is an ultra lightweight, 100% mineral sunscreen designed for daily use on the face. The sheer formula was developed with sheer zinc to provide maximum broad spectrum protection in a serum-like formula that applies easily to skin. It leaves a dry, matte finish ideal for application under makeup. The non-greasy formula will not clog pores or leave behind a white cast and is dermatologist and ophthalmologist tested to be safe for use on the face. Formulated with soothing vitamin E to comfort the skin, this sheer sunscreen locks in lasting hydration to help prevent against the drying effects of the sun. This sunscreen is hypoallergenic, fragrance free and paraben free, and designed to be gentle on even the most sensitive skin. Mineral sunscreens can often leave a white cast when applied as they contain titanium dioxide and zinc oxide which work to prevent sun damage by staying on the skin's surface. For best results, we recommend applying in thin layers and thoroughly massage into skin until it is fully absorbed (repeat as needed). Tip: Try priming skin with a light layer of your favorite moisturizing lotion and let is absorb before applying sunscreen.
