DNA sunscreen may mean you never have to apply it again
From being chased around the beach by our mothers in the attempt to slap on a fresh layer, to constant re-applications, it seems we are not too excited by the concept of sunscreen. But, we can't ignore the importance of sunscreen in our beauty regimes so here's the big news - scientists from the US are developing a sunscreen that uses our DNA to act as a second protective skin. Not only can we wave goodbye to greasy sunscreen hands, this new breakthrough potentially gives stronger protection against the sun's harmful rays.
DNA samples have been taken from salmon to develop this much-anticipated product. It is said to have numerous benefits, including locking in moisture for a long lasting tan.
Here's how it works:
When we get a sunburn, it is our DNA getting damaged on the surface of our skin so instead of us taking the hit, salmon DNA is applied to our skin to absorb the ultraviolet light. Assistant professor of biomedical engineering at Binghampton University, Dr Guy German explains, 'what happens instead if we actually used DNA as a sacrificial layer? So instead of damaging DNA within the skin, we damage a layer on top of the skin.'
The thin and transparent DNA film of the salmon became better at protecting our skin the more they are exposed to the UV light. So, the longer you stay out in the sun, the better the product becomes! Win-win.
The best part is, there's no need for reapplications. Usually, we'd be out on the beach tanning before remembering that it's been 30 minutes and that a sunburn is on the way. With the salmon DNA, a single application is enough. Although we're still waiting for the day sunscreen doesn't exist, this is enough to get us excited, for now.
