UVA, UVB, why are they harmful?

While the atmosphere acts as a natural shield against UV rays, UVA and UVB still manage to reach us.

Different in their intensity, wavelength, and ability to penetrate the skin more or less deeply, UV rays do not all “attack” us in the same way.

UVB reach the epidermis, are responsible for sunburns. In high doses, they can also cause irreversible damage by altering the DNA of skin cells.

UVA, on the other hand, are less energetic than UVB but we receive 1000 times more of them! Present all year round and from 8 a.m., they even pass through glass. They reach the dermis and deep skin structures, leading to wrinkles, spots, loss of elasticity, dryness…

One solution: protect yourself with good sunscreens suitable for your skin type!
