Apply a sufficient amount all over your body before going out in the sun. Repeat the application process after sweating, swimming or drying with a towel. In order for sun products to penetrate the skin, the application should be done 15-30 minutes before going out in the sun. If you stay in the sun for a long time, the product should be renewed every 2 hours. It should not be applied heavily on the face area, otherwise, it may cause acne.
