Vitamin D sure is a hot topic these days. About one third of the U.S. population has low levels, and it’s been touted as a cure-all for everything from depression to heart disease and skin cancer. With all the talk going on, there’s a lot of back-and-forth over the full range of D’s superpowers.
Here’s the thing: We already know that skin is a crucial catalyst and gateway for vitamin D to get to where it needs to in the body. “Vitamin D is primarily synthesized in skin exposed to UV light, if not obtained by diet or supplements,” explains Jean Y. Tang, M.D., Ph.D., assistant professor of dermatology at Stanford University School of Medicine.
And since over time, the skin’s ability to create vitamin D decreases (up to 75 percent from the age of 20 to 70) you’ll eventually have to pop more vitamin D supplements to reach standard levels than when you were younger. (That’s one of the reasons why Grandma is more likely to be diagnosed with osteoporosis, because of D’s crucial role in bone health.)
But does D play a much more superficial role? “Vitamin D is a key ingredient for beautiful looking skin,” says Dennis Gross, M.D., a dermatologist in New York City and creator of his namesake skincare line. “Skin, like all organs, needs vital vitamins to function properly—and vitamin D is one of them.”
Dr. Gross has spent the last few years researching the D-skin connection, really one of the only experts to do so in the dermatology community, making him a lone ranger of sorts. And the benefits he’s uncovered from poring over the existing vitamin D research and observing his own patients’ experiences are expansive. Having sufficient vitamin D in the skin helps minimize acne, boost elasticity, stimulate collagen production, enhance radiance, and lessen lines and the appearance of dark spots, he says. It’s this laundry list, plus anecdotal evidence from seeing patients day in and day out at his NYC office, that led him to create skincare with D right in the bottle. “Many of my patients have vitamin D deficiencies as a result of avoiding the sun and wearing a daily sunscreen in fear of premature aging and cancer,” he says. “Together, we noticed that their skin had a sallow and dull appearance, which I believed to be an adverse effect from low levels of vitamin D.”
After heading to the lab, Dr. Gross says he saw that popping a D pill wasn’t the only way to make sure you got enough of the much needed to your complexion—the skin could get it directly from a product. “I came up with a formula that I immediately began testing on patients and then witnessed a dramatic reversal of symptoms, even after one application,” he says. “I then began applying Active Vitamin D Serum-Oil to patients who weren’t deficient and noticed similar beneficial results. The immediate results were enough to convince anyone who may have originally been skeptical.”
