UVA rays: These are less likely to cause sunburn than UVB rays, but they penetrate your skin more deeply. Watch out because UVA rays can go through windows, lightweight clothing, and even your car windshield. Prolonged exposure cracks and shrinks the collagen and elastin in your skin, which is why UVA rays are responsible for signs of aging including wrinkles, saggy and leathery skin, and suns spots.

UVB rays: These are responsible for tanning your skin, but they also cause sunburn. UVB rays are the main culprit when it comes to skin cancer. These rays also go through windows, and it doesn't matter if it's cloudy — you're still at risk for exposure.
