Some sunshine is good for us. It helps regulate our circadian rhythm and stimulates production of vitamin D. But too much sun and too many sunburns increase our risk of premature aging of the skin and skin cancer.
Spend time outside when the sun's rays are least intense: in the early morning or late afternoon. If you are out during the hottest part of the day, when the sun is most intense, use sunscreen.
To find the safest and most effective products, read the
2012 Sunscreen Guide from the Environmental Working Group.
The updated Guide will help you find the best beach and sport sunscreens as well as top SPF products like lip balm, moisturizers, and makeup.
Look up products you already use to see how they measure up, check out EWG's Sun Safety Tips, or download the EWG Sunscreen Buyer's Guide and do it all from your mobile device.
