• UVA and UVB rays are ultraviolet radiation (part of the light spectrum) that comes from the sun. Ultraviolet rays are shorter than visible light, which is why you can't see them with your naked eye.
  • UVB rays hit your skin's surface and can turn you lobsterred. Ouch! UVA rays have longer wavelengths than UVB and can penetrate deeper into your skin, causing aging and longterm damage. Both UVA and UVB rays can cause skin cancer. Double ouch!
  • UVA accounts for up to 95 percent of the solar UV radiation reaching the Earth's surface.* UVA rays are present during all daylight hours and throughout the winter months.
  • UVB is responsible for burning, tanning, and acceleration of skin aging, and plays a very key role in the development of skin cancer.
