Digital images captured redness following the application of two different sunscreens with varying SPFs (an SPF 75 with 80-minute water resistance and an SPF 46 with no water resistance). Subjects and investigators were blinded to product administration. A single application (2mg/cm 2 ) of sunscreen was randomly applied onto a designated area on the backs of six healthy subjects (Fitz- patrick Skin Type II). Using an artificial source of UV (“solar simulator”), sunscreen protected skin was exposed to 40x, 50x and 75x each subject’s Minimal Erythema Dose or MED (the level at which an individual’s skin starts to appear pink). Sunscreens should be reapplied approximately every two hours or more frequently. For complete information regarding use and frequency please refer to the product drug facts.
