Shake well and apply evenly onto body at least 30 minutes before exposure to the sun. Re-apply frequently to maintain protection, especially after perspiring, swimming or towelling. In order to reach the protection level indicated by the sun protection factor, sunscreen products have to be applied in a quantity that is equal to 2mg/cm² (approx. 6 teaspoons for the body of one average adult person). Warning: Not using the adequate quantity of sunscreen will lower the level of protection significantly. Do not stay too long in the sun, even while using a sunscreen product. Over-exposure to the sun is a serious health threat. Wait until the product is absorbed fully, before you get dressed. Sunscreen products may cause stains on clothing.
