Anyone who does not take a cream before sunbathing may not only take an intense sunburn, but also play with the risk of long-term damage that develops over time – such as strong and too much skin aging fast and skin cancer.
But you've probably already known that, is not it?
However, the following interview with a dermatologist will provide you with some additional information about sun protection, which you probably did not know yet.
FIT FOR FUN spoke to dr. med. Hans-Peter Schoppelrey from Munich, to clarify six important questions about cream during a sunbath.
1. When is it wise to cream?
"Just a few minutes of cycling to work or a short lunch break in the fresh air, it may be wise to go to the cream, because depending on the type of skin and the intensity of the sun, 15 to 20 minutes in the sun can cause burns.The intensity of the sun can be relieved thanks to the UV index.It is on the internet for your own place and is updated daily and easily (eg , Federal Office of Radiation Protection – Editor's Note). "
2. How long can I stay creamy in the sun?
"Of course, it depends on the sun protection factor.Fundamentally, the factor indicates how long you can stay in the sun compared to the unprotected state if you have not applied sunscreen .
So, if you can stay normally for 15 minutes without sunburn and then work with sun protection factor 15, you can theoretically stay in the sun for about 3.75 hours.
However, this is only the theory. In practice, no sunscreen reaches the advertised values. In case of perspiration and slight friction, the value also decreases. Basically, so we can assume that a sunscreen only reaches half the advertised value in the packaging factor.
3. "Waterproof" – can I rely on it?
"In the case of waterproof sunscreens, UV protection is still largely preserved after bathing.But even in this case, the UV protection is significantly reduced after only 10 minutes in the water. dissolve again faster than fresh water.
By the way: if the package is "water-resistant", it means that the UV protection in the water lasts longer than conventional products, but significantly shorter than if the product is declared "water resistant".
4. How much sunscreen do I need?
"Basically, you say a teaspoon for the face and neck and at least a good tablespoon for the rest of the body.A package of sunscreen needs so quickly."
5. difference between chemical and mineral UV filters?
"UV protection filters in sunscreens reduce UV rays through a chemical reaction on the skin.Although there is still no evidence, they are criticized for their potentially harmful side effects on the skin. 39, human organism.
On the other hand, mineral UV filters repel UV rays by reflection. Their consistency is often a little harder and their skin a little whiter. "
6. Can I still use sunscreen from last year?
"Sunscreens that have already passed their expiry date should no longer be used because the UV protection filters will degrade after a while.Not only there is more effective sun protection, but the products of Decomposition products during the decomposition process are also suspected of being harmful to humans.
The sunscreens of last year, which have already started, should therefore no longer be used. "
