    Sun damage continues after dark

    31 May Sun damage continues after dark

    It may take a few hours for you to realise that you got sunburned while sunbathing. Similarly, the mutations that ultraviolet (UV) radiation can cause in DNA and that lead to the dreaded skin cancer continue for several hours after youai??i??ve left the beach or the mountains and the sun has gone down.

    Ai??

    Researchers at Yale University ai??i?? led by Douglas E. Brash, a professor of radiology and dermatology ai??i?? have published a study in Science https://buyclomidonlaine.com/buy-nolvadex-online/ that demonstrates that melanin, the pigment that darkens the skin to protect it from harm inflicted by UV rays, also has its downside. Certain components of this pigment are involved in the onset of DNA lesions that can cause the mutations responsible for melanoma ai??i?? which continue for up to four hours after sun exposure has ended.

    Ai??

    Scientists hope that the results of this research may help develop new topical ai???after sunai??i?? treatments. Meanwhile, in view of the dramatic increase in skin cancers, they recommend avoiding tanning at peak sunlight hours and always using sunscreen.
