UV Radiation

There are many different types of rays that come from sunlight, but there are two basic types of ultraviolet radiation that reach the earth’s surface. The rays that reach earth are known as UVA & UVB.

  • UVA Radiation

These rays that penetrate the skin more deeply are associated with wrinkling, leathering, sagging, and other signs of aging. UVA rays can also exacerbate the cancer causing effects of UVB rays. They are increasingly being seen as a cause of skin cancer on their own.

  • UVB Radiation

The rays that primarily cause damage to the skin, premature aging, and increases your risk of skin cancer is UVB rays. UVB is also the chief culprit behind sunburn.

Skin Protection

Sunscreens vary in their ability to protect against UVA and UVB radiation. SPF — or Sun Protection Factor — is a measure of a sunscreen’s ability to prevent UVB from damaging the skin. Most sunscreens with an SPF 30 or higher do an excellent job of protecting against UVB. Make sure your sunscreen is SPF 30 or higher to get the protection you need against the damaging rays of the sun.
