The St. Tropez Sport Lotion is a fast and clear drying oil free sunblock that is both water and sweat resistant. A sunblock is different than sunscreen due to the ability of sunblock to reflect light away from your skin. St. Tropez Sport Lotion provides UVA and UVB protection while replenishing lost moisture with aloe vera. St. Tropez Sport Lotion has a Sun Protection Factor (SPF) of 15. Use daily as a moisturizer and protective base under make-up to reduce the chances of premature aging and skin cancer caused by exposure to the sun and other harmful UV rays. PABA-Free. TIP: Apply St. Tropez Sport Lotion 20-30 minutes before exposure. Make sure to use at least 1oz. of product and apply thickly. For reference 1oz. fills a shot glass.
