According to Dermatologists, tanning isn’t bad for you just because it comes with the risk of burning, which can cause skin cancer. Tanning is bad for you because your body doesn’t even begin to tan until dangerous UV rays have pierced your skin and started to mess with your DNA.
Some people think a base tan will protect them, but that logic doesn’t make sense. You’re doing so much damage just get that little bit of protection according to Dermatologists.
It’s true that melanin can protect the body to some extent against UV rays, it absorbs UV rays to a point, acting as the skin’s natural sunscreen. But the process of adding an extra dose of melanin to the skin is actually a defense mechanism that begins only after damage has been done.
UV-A and UV-B cause the kind of DNA damage that can lead to skin cancer, but UV-A in particular can break down the natural collagen in the skin, which can lead to premature aging.
No anti-aging product, even the dermatologist-recommended ones, can slow skin aging as much as simply using sunscreen in the first place.
Dermatologists say people should make sure to use sunscreen when being exposed to the sun.
