Sunscreens are skin products designed to help protect your skin against ultraviolet (UV) radiation from the sun. UVA and UVB radiation can seriously damage your skin, increase your risk of skin cancer, and make you look older than you are. Everyone over six months old should use sunscreen and babies under six months should not be exposed to the sun.
Sunscreens come in many varieties and strengths. A light sunscreen with a protection rating of SPF 15 is sufficient for everyday exposure, where you’re only exposed for a few minutes at a time throughout the day. If your job is outdoors, especially if you sweat a lot, you’ll need more protection and you should apply it more often.
For best results, be sure to apply sunscreen 30 minutes before you head outdoors. That will give the sunscreen time to bind with your skin before you sweat. Reapply every two hours and after you swim or towel off. If you burn easily, choose a sunscreen with a high SPF and watch your skin for telltale signs of burn, redness and tenderness.
