UV rays have the power to damage collagen and elastin in the skin causing fine lines, wrinkles, dark spots and burns. Wearing a daily sun protection product such as Obagi Sun Shield Matte Broad Spectrum SPF 50 can help prevent this damage so you avoid these signs of aging. The formula contains physical and chemical sun protection ingredients that defend against both UVA and UVB rays. Unlike many sunscreens, this formula does not leave a white film or a greasy texture. The matte formula reduces the look of shine and sweat so your complexion appears radiant, not oily.
