UVA Rays

UVA rays are constantly present, no matter the season or the weather. If you think you can't get sun damage on a cloudy day, tell that to the UVA rays. They are so powerful that they also penetrate some clothing and even glass.
UVA rays used to be considered relatively safe, in terms of the sun's rays, and that's why tanning beds, which use UVA rays, took center stage.
Also UVA rays are the rays responsible for the signs of aging because they are able to penetrate much deeper into the surface of the skin, damaging the cells beneath.

While people think their skin looks younger because it's tan, the reality each, each tan is giving your skin irreversible damage, and you will see it's damage later in life.

When you think of UVA rays, think sun spots, leathery skin and wrinkles.

UVB Rays

UVB Rays are the rays you can blame when you get a sunburn. Unlike UVA rays, these rays aren't always the same strength year round - They're more prevalent in the summer months, however they are able to reflect off of water or snow, so it's always important to protect yourself year-round.

UVB rays are responsible for causing most skin cancers. While large doses of UVA rays can contribute to cancer, it's the UVB rays that are commonly to blame.

If you've heard the advice to stay out of the sun though the mid day hours, it's the UVB rays you're trying to avoid. They are most prevalent mid day, so if you must be out at that time, protect your skin.

When you think of UVB rays, think sun burn and cancer.
