Sun Can Damage Skin Any Time of the Year
Skin damage from unprotected exposure to the sun can
occur any time of year, even during the winter.
“The highest level of concern is usually during the
summer months, but sun damage can occur year-round, even on cloudy or rainy
days,” said Sarah L. Taylor, M.D., assistant professor of dermatology at Wake
Forest Baptist Medical Center. “In fact, many people don’t realize that you also
get sun exposure through windows at the office, at home or in cars, which is
why dermatologists recommend that everyone wear broad-spectrum sunscreen every
day, all year.”
Taylor offered some simple steps to prevent sun damage
- Broad spectrum, physical blocker sunscreens
with zinc oxide or titanium oxide with 30 or higher SPF are best.
- Overapply liquid sunscreen, not sprays,
including sides of face, ears, front and back of neck, hands and arms and any
other skin that is exposed.
- New powder sunscreens make it easier to
reapply (even over makeup) during the day. Try to reapply every two hours if
there is a lot of sunlight in your office or workplace.
- A common misconception is that using multiple
products with sunscreen, such as a moisturizer and makeup, provides double the
protection, which isn’t true, Taylor said. In fact, some sunscreen ingredients
can deactivate others.
There is also scientific evidence that certain supplements
may help decrease the effects of UV radiation on the skin, Taylor said.
- Polypodium leucotomos, which is derived from
a Central and South American fern, has been studied in Europe. A daily dose of
240 mg as an oral supplement is considered safe. Fernblock and Heliocare are
two widely available brands.
- Niacinamide, one of the B vitamins, is
considered safe at doses of 500 mg taken twice a day.
“People may also want to use prescription retinoids to
treat the signs of photoaging. Differin, which is less irritating and much less
expensive than other retinoids, is now available over the counter,” Taylor
Taylor stressed that any woman who is pregnant or trying
to get pregnant should consult her physician before using any topical sunscreen,
retinoid or nutritional supplement. 1/31/2018http://www.wakehealth.edu/News-Releases/2018/Sun_Can_Damage_Skin_Any_Time_of_the_Year.htm
