UVA vs UVBWhile we are sitting in our cars, the sun is emitting two rays that can harm our health.
- UVA: The UVA rays are often associated with tanning as they’re the ones that will change your skin’s color. However, don’t think that means they’re good for you. A sun tan is actually a direct result of skin damage. It’s your skin’s way of trying to protect itself by building up more melatonin in the skin.
- UVB: The UVB rays are also dangerous, they’re the rays that actually cause sunburn, which is also a result of sun damage, and ultimately lead to the most harmful effects in your skin, like causing wrinkles and all the other signs that we generally associated with aging.
