Why should I use sun protection products?
Sun protection products help protect your skin from ultraviolet (UV) rays.
You can’t see UV rays from the sun! There are three types of UV rays:
- UVA rays go deep into skin to cause damage like wrinkles, sagging and tanning. UVA rays pass through window glass. Tanning booths emit primarily UVA rays.
- UVB rays are shorter and stronger than UVA. UVB rays burn the top layers of the skin.
- UVC rays are strongest and most dangerous. Luckily, the ozone layer keeps them from reaching earth.
Choosing and using sun protection products
Look at the SPF
Sunscreen products contain active ingredients that absorb into your skin to provide sun protection within the skin layers. The Sun Protection Factor (SPF) number on the product label tells you how long the product will protect your skin from burning UVB rays. Use a sunscreen with a SPF of 30 or higher.

These products have ingredients that absorb into your skin and block or absorb both harmful UVA and UVB rays from ever penetrating your skin. Use products that contain one of the following to get broad spectrum protection:
Is it water resistant?
Sun protection products may be labeled “water resistant”. These must still be reapplied every 40-80 minutes if you have been in water, or sweating.
