DNA Sunscreen – News – DailyBeauty – The Beauty Authority

We’ve seen sunscreen in powder, mousse and finishing-mist
formulations, but the latest innovation is here to blow the rest out of the
water. Medical researchers at Binghamton University in New York have recently developed
a sunscreen coating made out of DNA that gets stronger the longer you expose it
to the sun, meaning there soon may be no need to reapply your SPF, even at the beach.

“Ultraviolet light can actually damage DNA, and that’s
not good for the skin,” said Guy German, assistant professor of biomedical
engineering at Binghamton University in a press release. “We thought,
let’s flip it.” The result is a sunscreen that uses DNA as a “sacrificial
layer,” as Germain says, explaining that instead of damaging DNA within the
skin, a layer on top of the skin is compromised instead, leaving the skin untouched.

According to Yahoo! Beauty, German and his colleagues purchased
DNA that is readily available from scientific distributors to create
water-based DNA solutions. When the DNA compound is coated on a surface, they
dry out and form solid films. They are transparent to the naked eye, but when
placed under a microscope, these films were found to make up DNA crystals.

The more the researchers exposed the DNA-based
film to UV light, the better the film got at absorbing the light. “If you
translate that, it means to me that if you use this as a topical cream or
sunscreen, the longer that you stay out on the beach, the better it gets at
being a sunscreen,” German says.

He states that the film has huge hydrating
effects, explaining that skin coated with the material can store and hold much
more water than uncoated skin can, and theorizes that these films may be a good
option for those who want to see how their wounds are healing without needing
to remove any dressings.
