科學家們研發(fā)出了一種新藥，該藥物不僅能模擬太陽光曬黑皮膚的過程，還可以讓使用者免受紫外線輻射的影響。通過一系列對皮膚樣本及實驗鼠的測試，科學家們發(fā)現(xiàn)該藥令皮膚產(chǎn)生了一種呈棕色形態(tài)的黑色素。證據(jù)顯示，就連在陽光下也曬不黑的紅發(fā)人士們也能嘗試這種藥物。這支來自麻省總醫(yī)院（Massachusetts General Hospital）的科研團隊希望他們的發(fā)現(xiàn)可幫助人們預防皮膚癌，甚至減緩皮膚衰老的過程。請聽報道。

The secret to sun-kissed skin is melanin. When the Sun’s blistering rays hit your skin, they cause damage that can lead to cancer. So the skin throws up a protective barrier of brown melanin. It’s the body’s own sunblock and absorbs dangerous UV radiation.

The new drug, developed at Massachusetts General Hospital, is rubbed into the skin. It stimulates the same tanning effect just without the damage. The researchers’ goal is to give people a natural tan that protects against UV and cuts skin cancer rates.

The drug could allow those with the palest of skins to get a safe tan. But whether you’re ginger, blonde, or brunette, you’re in for a wait. The researchers want to perform more safety tests before bottles of real tan reach the shops.
