A "space drink" developed by NASA to protect astronauts from radiation can also reduce wrinkles and reverse the tell-tale signs of ageing in just four months, say researchers, following a human trial. A team at Utah University has found in its research that the concoction, known as AS10, dramatically reduces wrinkles, blemishes and sun damage after four months. At the start of their trial, the researchers took visia photographs -- which reveal the condition of the skin below the surface by using different types of light exposure - of 180 participants. They again took the photos after four months of drinking two shots of AS10 a day. By the end, UV spots were reduced by 30 per cent and wrinkles by 17 per cent, the 'Daily Mail' reported. AS10 was developed as a nutritional supplement for astronauts to protect them from the damaging effects of high levels of radiation outside the Earth's atmosphere. The drink contains a blend of fruits including cupuacu (a Brazilian fruit from the cacao plant family), acai, acerola, prickly pear and yumberry, which all provide vitamins and phytochemicals -- compounds known to block the harmful effects of radiation. Other ingredients are grape, green tea, pomegranate and vegetables.
