Since 1851 Kiehl’s has been making outstanding products, and one of our favorites is the Cross-Terrain UV Skin Protector SPF 50. It offers UVA & UVB protection at a SPF 50. You will be able to take advantage of it’s protection year round. Since it is water, sweat and wind resistant. Believe us they tested it. Kiehl’s extensive testing was facilitated by partnering with the National Geographic’s Young Explorers Program. They had four of the world’s top young explorers test the UV Skin Protector under some very extreme conditions. So you should be okay lounging around the pool.
