New Research Suggests This Vitamin May Help Protect Skin From UV Exposure

Something you're probably already doing? Including vitamins in your skin care routine—be it a hydrating vitamin E serum or a topical vitamin C treatment to improve skin tone. Eating with your skin in mind is just as important, and a new study suggests that one of the most popular topical ingredients may just be worth adding to your diet, too.

In order to test the efficacy of vitamin B3 consumption for protecting skin cells, the researchers treated individual cells with nicotinamide, a form of B3. They then introduced those cells to UV exposure and saw that the vitamins helped protect the cells from oxidative stress.

As mentioned by Camillo, one of the best things about this new knowledge is how easy it is to integrate sources of vitamin B3 into your diet. Though they mention consuming it within the day or two before your sunny plans, it may be worth just considering working these foods into your diet on a regular basis—after all, we wear our SPF every day even if we don't plan a jaunt into the sunshine, right?

What we eat affects our skin; this we know to be true. But it's always a delight to see the various unique ways certain ingredients actually do so. In the case of vitamin B3, we've been fans of using it topically for some time—so hearing that eating it may help ease and prevent sun damage? Well, now we're fully on board.
