Walgreens SPF 50 Advanced Sport Sunscreen protects you from the sun's harmful UVA and UVB rays with an innovative, broad-spectrum formula that is free of oxybenzone, octinoxate, and parabens, which are known to harm coral reefs. This enhanced, antioxidant-rich formula helps counter the effects of environmental stressors such as smog, infrared (IR) light and high energy visible (HEV) light - light that penetrates the deeper layers of the skin, causing the formation of free radicals and uneven pigmentation.
