Study, Sun Continues to Harm the Skin Even after You Take Your Shower

It is known that the sun can burn the skin as it harm the DNA. As reported from the latest study, it can even cause cancer and goes on to do its damaging effect on the skin even when the exposure has stopped.

It’s like when you’re  swimming in the open sea or taking sun a bath on a sunny day and decided to stop and take a shower afterwards.

The study that was published in the journal Science says that it is commonly known that those with lighter skin are more sensitive to the heat of sun. It was found that melanin which has the capability of protecting the skin could at the same time have something to do with damaging it.

“Sure, blondes and redheads are more sensitive to sunburns and skin cancer,” Douglas E. Brash, who is the author of the study, a professor of therapeutic radiology and dermatology at Yale said. “But then you look at countries like Egypt, where many people have fairly light skin tones, and there isn’t the high skin cancer incidence you’d expect. So I was never sure I bought that the lightness of the skin was the issue.”

The study was conducted by Brash with his colleagues as they proceeded to examine how melanin could possibly be associated with it. Based on some studies before, kinds of melanin ratios that generate a lighter skin hair colors could make a person even more at risk to skin cancer. However, when UV rays were applied to the cells, an unexpected result came up. After the researchers stopped applying the light, it kept on destroying the cells instead.

“The sun damage we understood before had a photon getting through your skin, if it didn’t get absorbed by melanin first,” Brash explained. “And it happens quickly, and then it’s done. But we saw a second process that took hours. It protects us from some of the damage,” Brash said, “but it also causes some of it. It was an interesting finding, but it felt kind of heretical.”

“I’d give people the same advice they’ve heard before,” Brash said. “Stay out of the sun between 10 and 2, wear a hat, wear sunscreen.”
