What you need to check on the sunscreen label

Here are some simple tips for sunscreen selection and use from CNN:

- Use a sunscreen with a minimum of SPF 15 and a maximum of SPF 50. SPF 15 can block 93% of incoming UVB rays. SPF 30 blocks 97%. SPF 50 blocks 98%.

- Make sure labels list both UVA and UVB protection

You get exposed to both UVA and UVB light:

UVB light is the light that Burns (causes sunburn)
UVA light as the light that Ages the skin (wrinkles, etc.)

- Avoid products containing oxybenzone and retinyl palminate. They may get absorbed through the skin and may increase cancer risk

- Choose lotions versus spray sunscreens for a more evenly distribution

- Remember to apply at least 2 ounces of lotion (about a shot glass full). Reapply every 2 hours. Reapply after swimming or heavy sweating.
