The Importance of SunscreenMany people think of sunscreen as something that's needed only for long days at the beach or hiking in the bright sun. But given the fact that even moderate exposure to ultraviolet rays can seriously damage skin, it's far wiser to get into the habit of using sunscreen, and other sun-blocking strategies, on a daily basis.
Diane V. Duvall, M.D. graduated from Emory University School of Medicine where she served as Chief Resident in dermatology. She is a Board-Certified Dermatologist with Georgia Skin Care Specialists and lives in Atlanta with her husband and two children. Here she explains why sunscreen is so important to healthy skin:
- Sunscreen helps prevent skin cancer.
Sunscreen is a topical product that's applied to the skin to protect against sunburn and the harmful effects of ultraviolet light. According to Duvall, using sunscreen regularly can help prevent skin cancer and photo aging, which is a change in the skin that gives the appearance of aging.
- Use it even for short stays in the sun.
Duvall believes that anyone planning to be out in the sun for thirty minutes or longer should apply sunscreen to all of their exposed areas.
- Use it even on cloudy days.
The very best way to protect the skin from ultraviolet light is to wear sunscreen every single day. Even when the sky is cloudy, the harmful rays of the sun are getting through.
- Cover up in the sun.
Even more important, says Duvall, is developing a complete sun protection regimen which includes sunscreen, wearing wide brimmed hats, and seeking shade whenever possible. Wearing sunglasses that contain UV protection is also a good idea, as UV light can damage the retinas.
