This Body Milk was specifically formulated to protect against all the suns' rays. Not only does it protect against UVB and UVA, it also protects the skin against infrared and visible light rays, which are the main culprits in premature skin ageing. This product is perfect for those who burn easily and tan slowly. To use: Apply liberally before exposure to the sun. Re-apply throughout the day, especially after contact with water or perspiration, for continued protection.
