The Effect of the Sun on the Skin
Sunshine increases the well-being of most people, but scientific findings also show more and more clearly the risks that can arise for our skin.
The invisible UVA and UVB rays, are dangerous, especially because the can't be felt on the skin immediatley. The ultraviolet radiation, which is very rich in energy, is not only capable of causing a temporary sunburn, but also steadily progressing light damage in the connective tissue of the dermis, which is only noticeable at a late stage. All these processes can lead to irreversible changes (e.g., premature skin aging) and serious health risks (e.g., skin cancer).
The effect of the sun on the skin
Despite the risks, you do not have to avoid the sun entirely if you follow important but simple sun protection measures, e.g.:
- How do I properly apply sunscreen to the skin?
Any sunscreen should be spread evenly onto the skin and then allowed to absorb on its own. Do not rub the sunscreen into the skin, as this reduces the thickness of the protective layer and thus the protective performance.
- How often and in what quantity should you apply the sunscreen?
The sun protection factor can simply be decreased if the amount of cream used is too small. For an adult, we recommend about 25 ml per application. The application of sunscreen should be repeated every 2 hours, due to sweating and abrasion, from when you lie on a towel for example, which will cause the protective film to become too thin. Waterproof products must also be reapplied after a longer stay in water and after each drying with a towel.
- What should be considered for babies and toddlers?
Babies and toddlers up to the age of about 3 years should be protected from any direct and prolonged exposure to the sun, as their skin is much more sensitive. The best way to do this is to wear a head covering and clothing with special UV protection. Exposed areas of skin should always be protected by sunscreen (at least SPF 25).
- What is particularly important for sensitive skin, e.g., atopic eczema? For people with sensitive skin, e.g. with a tendency to atopic eczema, good sun protection is very important. If the skin is not sufficiently protected, severe itching or inflammation can occur. In addition, the sand and water can irritate the skin. Those with atopic eczema should use sunscreen products with a high sun protection factor. When buying a sunscreen product, make sure that it contains as few preservatives as possible, as these can additionally irritate the skin.
- What should I bear in mind when sunbathing?
Between 11 a.m. and 3 p.m., you should avoid the sun altogether, as UV intensity is highest at this time. You should also not forget the tip of your nose, ears, the back of your neck and the backs of your feet when applying sunscreen!
