Wondering the Difference Between UVA & UVB?

Ultraviolet B:
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. 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.

Ultraviolet A:
UVA rays are constantly present, no matter the season or the weather. 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. UVA rays penetrate deep into the dermis, the skin’s thickest layer giving you a longer lasting tan!
