Creams for sun tanning the future will work on a completely different principle. American scientists have learned to protect skin cells from damage to DNA without preventing sun rays from entering it, and by stimulating the natural processes of repairing damage. Thanks to this method, the experiments succeeded in significantly reducing the likelihood of developing skin tumors.

In this experiment, scientists from the Faculty of Medicine at the University of Boston were exposed to ultraviolet rays by the skin of laboratory mice. One group of mice received protection, the active component of which was a nucleic acid fragment similar to that of the DNA. Thymidine dinucleotide (pTT) penetrated the skin, fighting in mutations arising in cells.

As the head of the study David Goukassian (David Goukassian), thanks to the protection of skin tumors in mice appeared six times less often.

The scientists explained that the penetration of pTT into the skin causes the activation of the defense system against mutations through the p53 protein. Thus, when the rays begin to damage the skin, the protection is already active and ready to withstand cell damage.

The authors of the work, published on the pages of Proceedings of the National Academy of Sciences, said that the next step in the experiments to create a next-generation tanning cream will be tests on volunteers. En.
