The New Sunscreen that Doesn’t Block Vitamin D
February 8, 2016
Researchers from Boston University Medical Center have created a new way to develop a sunscreen that will both protect you from harmful rays while still allowing your body to produce vitamin D. Their approach is outlined in the journal PLOS One.
A typical sun lotion with a SPF of 30 reduces the skin’s capacity to produce vitamin D by almost 98%. But Solar D, developed by an Australian company, strips out some of the UVB-blockers, allowing your skin to produce up to 50% more vitamin D.
By changing the chemical compounds, the researchers created Solar D, which is SPF 30, with the aim of helping people get more natural vitamin D daily.
Problem is, blocking UVB rays is a very, very good thing. UVB rays are the reason you get sunburns, and they also cause premature aging and skin cancer. Solar D still protects you from most of the sun’s UVB rays but does allow one specific wavelength of light to reach your skin to start the process of vitamin D synthesis. Some experts are skeptical.
“It only takes a few minutes of sun exposure for your body to produce the vitamin D it needs daily,” says Sejal Shah, M.D. a dermatologist in New York City. “Too much ultraviolet exposure can actually break down the vitamin D in your body.”
Solar D is already sold in Australia, with plans of coming to the U.S. market in summer 2016.
