How much sunscreen has to be applied so that the skin is properly protected?
Sunscreen should be applied to the skin’s surface at 2 mg per cm2 so that it can provide optimal and complete sun protection. A good rule of thumb is: 3 grams of creme for the face (corresponds to about a teaspoon) and 30 grams for the body (a generous two tablespoons). Not applying a sufficient layer of the product seriously reduces the sun protection factor. Do not forget to apply sunscreen to the tips of your ears, your eyelids and the bridge of your nose because these areas get a lot of sun exposure. The neckline, forehead as well as the tops of your feet are also often neglected, as well as areas bordering your clothing, for example, under the straps of your swim suit. Your lips are the most sensitive because they are unable to build up their own protection.
