Is it safe to get a "basic tan" in summer?
no. There is no safe amount of tanning.
Tanning is not bad for you, just because it involves the risk of burns that can cause skin cancer. Tanning is bad for you because your body does not even start to tan until dangerous ultraviolet (UV) rays have punctured your skin and started to mess up your DNA.
And that alone significantly increases the risk of skin cancer, Dr. Roxana Daneshjou, a dermatologist at Stanford University School of Medicine. [5 Things You Must Know About Skin Cancer]
"There's really no safe tanning except … putting a wrong color on the skin," Daneshjou told Live Science. "Fair-skinned people can not even tan until they burn."
And while burning represents a greater danger ̵
"Some people say, 'Well, I should tan myself because the extra melanin will protect me.' But this logic does not make sense, you do so much damage just to get a little protection, ' she said.
Melanin is a pigment found in skin cells when UV rays strike the skin. The more melanin is produced, the darker the tan. (And people with more melanin in their skin have darker skin tones.)
It's true that melanin can protect the body to a degree from UV rays – it absorbs UV rays to a point that is more natural Sunscreen of the skin works, said Daneshjou. But the process of adding an extra dose of melanin to the skin – in other words, tanning – is actually a defense mechanism that starts only after damage has been done.
Daneshjou also noted that people who brown for aesthetic reasons, injure themselves permanently. [7 Beauty Trends That Are Bad for Your Health]
Dermatologists classify the dangerous portion of UV light into two categories: UV-A and UV-B. Both cause the type of DNA damage that can lead to skin cancer, but UV-A in particular can contribute to a second problem: it breaks down the natural collagen in the skin, which can lead to premature aging.
"Collagen is the supportive structure for the skin," said Daneshjou. Without the support structure, she said, skin folds, thinning and weakening, attracting a paper-like appearance.
No anti-aging product, even the dermatologist-recommended, can slow down skin aging as much as easy to use with sunscreen in the first place, she said.
Daneshjou said, to avoid such problems, dermatologists recommend to use any (light or dark) sunscreen (broad-spectrum products or clear as protection against UV-A and UV rays) B) year-round. UV-B exposure increases in summer and decreases in winter, but UV-A exposure occurs year round. And both forms of UV light can penetrate clouds and cause damage on cloudy days.
"People say, 'Oh, I do not spend time in the sun & # 39 ;," Daneshjou said. But such people should still wear sunscreen. UV light penetrates car windshields and can cause damage even on short walks.
Daneshjou said that in a typical summer outfit, people should use a sunscreen against their sunscreen.
