3 Things You Didn't Know About Sun Spots
There are a few things you definitely know about sun spots, like you don't want them, and wearing sunscreen is the best way to prevent them. But beyond that, things get a little fuzzy. Here are three facts we bet you didn't know about preventing and treating these spots. [Source: Allure.com]
They're not always caused by the sun. When your skin is irritated, melanin production increases. And some of the most common causes of irritation include waxing, gritty facial scrubs, and pimples (especially if you pick at them). Switch to gentle scrubs with microbeads and dab 1-percent hydrocortisone cream over freshly waxed skin and pimples for a day or two to prevent irritation, says Joshua Zeichner, a dermatologist in New York City.
You can catch them before they surface. Many people have sun spots lurking under their skin by age 30, but there's good news, too: If you treat a spot before you actually see it, you can prevent it from surfacing, says Zoe Draelos, a consulting professor of dermatology at Duke University. Use a cream or serum with brightening ingredients such as licorice or vitamin C in the morning, and exfoliate at night once a week.
Once a sun spot surfaces, the sooner you treat it, the better. Melanin penetrates deeper into skin over time—and then it's harder to erase, explains Jessica Wu, a dermatologist in Los Angeles. Your best bet is to begin using retinol at night within six months of seeing a sun spot.
