What is the problem of “basic tanning” and why are UV rays not safe?

We hope you carefully read our texts on the topic , and therefore you know perfectly well that going out without a means with SPF in the summer is not just unreasonable, but also very dangerous. However, sunburn is bad not only because of the risk of sunburn and skin cancer. The main problem here is that your body does not even begin to sunbathe when dangerous ultraviolet rays already penetrate the skin and have a detrimental effect on DNA.

Let’s start with the main thing: there is no safe amount of sunburn. In any doses and under any conditions, only if it is not self-tanning towels , it increases the risk of melanoma. “People with darker skin and generally can not get tanned until their skin burns out, so it’s important to remain vigilant,” says Live Science Roxana Daneshjou, an expert in dermatology at Stanford University ).

Yes, the burn is really associated with a significant danger, because it is about such a serious damage to cells by the sun’s rays that they die. However, the damage to the skin, which starts from the very beginning of the tanning process, is no less dangerous.

“Some people believe that they should sunbathe at least a little, because an additional melanin can protect them. But this logic does not make sense, because in the end you are causing serious damage to the body, which can not be compared to the insignificant protection that you receive, “Danesu explains. Recall that melanin is the pigment of the skin that absorbs UV rays that get on the skin. The more the sun acts on you, the more melanin works and the darker the skin becomes. If the skin is dark initially, then this indicates that it contains more melanin.

And yes, it’s true that melanin is able to protect the body from ultraviolet rays to some extent. “It blocks a certain percentage of the rays, acting as a natural sunscreen,” notes Roxana Danesu. “But the process of adding an additional dose of melanin to the skin – in other words, sunburn – actually becomes a protective mechanism only after the damage was done.”

Dermatologists divide a dangerous part of UV radiation into two categories: UVA and UVB. Both types of rays adversely affect DNA and can lead to its damage, but UVA while contributing to another problem – destroying the natural collagen in the skin, they provoke premature aging .

“Collagen is the structure of skin support. Without it, the skin frowns, thinens and loses its elasticity, acquiring an appropriate appearance, “explains Danesha. According to her, anti-aging products, even recommended by dermatologists, can not always slow down the aging process of the skin. But this can make an ordinary sunscreen, if you use it regularly and correctly .
