Do you also think about going to the solarium for pre-tanning? But is pre-tanning really a protection for the skin?
Juhuuuu, the sun is here! Now we finally want to wear shorts and short dresses. Yikes, but what is it? Pale legs that have not seen sun for months! So go to the solarium and pre-tanning, before it finally goes on vacation. Because then we want to hit the turbo-tanner again. But does that really help? Does tanning in the solarium really make sense?
That's why your skin will turn brown
Tan is actually a protective mechanism of the skin . If UV rays hit the upper horny layer, it thickens and forms so-called light-colored calluses. If the UVB light penetrates even deeper into the skin, the pigment melanin is formed. This shows up as a brownish color on the skin.
The more pigment cells present and the finer these cells are distributed, the faster you turn brown. The distribution and number of pigment cells depends on the skin type.
What is a light calli?
The term for a natural protective barrier of the skin is hyperkeratosis. It is a thickening of the cornea in response to UV-B radiation. The calluses allow the skin to absorb more UV-B light. A hyperkeratosis develops after about 3 weeks of sunbathing. As a result, the skin develops its own protection equivalent to something SPF 5. When the sun's rays are removed, the natural skin protection disappears again.
Can I build up a glow of light in the solarium?
No, because the radiation used in the solarium is mainly UV-A radiation . However, a hyperkeratosis only occurs due to UV-B radiation . And you can only find them in natural sunlight. The skin tanned by the solarium looks good, but does not protect against sunburn.
Do I have to use sunscreen despite the lack of light?
Yes, because, as already mentioned, it takes until the glow of light has developed, and even then it only corresponds to sun protection factor 5. A person with fair skin should therefore never go to the sun without higher SPF. A sun protection factor of 30 and not too long in the direct sun is always better, even with darker skin types.
