EltaMD sunscreens help prevent not only sunburn and skin aging, but also reduce the risk of skin cancer due to UV radiation. EltaMD features a variety of effective, water-resistant, clear or tinted sun blocking lotions suitable for all skin types. They are formulated with transparent zinc oxide and are fragrance-free and paraben-free. Of the various medical grade sunscreens we use ourselves, EltaMD is one of our favorites.
