What could be better than lazing lazily on the beach or relaxing in the sun with friends? And to get a crispy brown by the way? In order for you to enjoy your sunbaths without regrets, you must first know what type of skin you are, that is, how your skin reacts to intense sun exposure, and secondly, which one. Solar protection Is it suitable for you. Mädchen.de explains the most important differences in sunscreen, SPF (sun protection factor), and UV / UVB radiation.
What does SPF mean?The sun protection factor (SPF or SPF, sun protection factor) indicates the effectiveness of a sunscreen: a high sun protection factor means high sun protection (from SPF 30), a lower SPF (up to SPF 10) for a correspondingly lower protection. It indicates how much longer you can be in the sun with a sunscreen product without getting sunburned than would be possible with individual self-protection time.What is the UV index?The UV index indicates the intensity of UV radiation. Its values apply to all skin types. In Germany, the values are on average between 0 and 8. In the tropics, values of up to 12 can also be reached. The UV index always refers to the maximum daily value of UV radiation when UV rays are most dangerous, on the days sunny around noon. You can find the current UV index values on the Internet at the German Weather Service or the Federal Office for Radiation Protection.What do UV-A and UV-B radiation mean?UV rays are short for ultraviolet rays. They are generally divided into two types: UV-A rays tan the skin, but can cause wrinkles at first. UV-B rays, on the other hand, can cause sunburns and even skin cancer.
Sunscreens should not only protect against sunburn caused by UV-B radiation, but also prevent premature aging of the skin, damage to the immune system, and skin cancer caused by UV-A radiation.
Beta carotene as sun protection
It is also called provitamin A. It is only found in plant-based foods. Beta carotene is an active ingredient that can absorb UV rays and therefore acts as a sunscreen for our skin. Particularly good suppliers are bright yellow to orange fruits and dark green leafy vegetables – carrots, spinach, broccoli, and lamb’s lettuce, for example. Beta carotene also acts as an antioxidant and protects against free radicals. Important: beta-carotene can only be used by the body if the fat is absorbed at the same time.
Melanin color pigment
Melanin is a color pigment that is produced by the body and gives skin, hair, and eyes their specific hue. It also protects the skin from harmful ultraviolet rays and heat. That is why it forms more and more when exposed to sunlight and causes the skin to darken.
When does a sunburn occur?
If you have been in the sun for too long, you get sunburned, because too much sun exposure can damage cells and cause skin inflammation. You notice it because the skin becomes red, hot, painful, and flakes off later. Extensive sunburns can also cause blisters, fever, nausea, and circulatory problems. Depending on the intensity, sunburn will heal after a maximum of two weeks. What remains is a thickening of the horny layer and tanning (pigmentation) of the skin.
