People around the world spend billions of dollars every year trying to look younger. Companies produce thousands of creams（护肤霜）, pills and treatments for our skin to look younger. In addition, scientists have worked for many years on trying to slow down the ageing process.
This week, scientists made a breakthrough（突破）. They have developed a method to "time jump"cells in human skin. The scientists are from the Babralham Institute in Cambridge, UK. They said they could turn back the ageing clock in cells by 30 years. They added that this could make skin look younger. Skin cells in their tests kept all of the important functions （功能）. The scientists said their work was still at an early stage, but they were sure it could help people look younger in the future.
The technique developed by the scientists could change medicine and health. The lead researcher, Dr Diljeet Gill, said, "So far, we've only tested this technique in skin cells. We're excited to see if we can translate it across other cell types. "This means it could be used to treat skin problems. The scientists hope their technique could also be used to help other parts of the body. Their new method could also help to heal （愈合） cuts more quickly, especially in older people. Researcher Dr Wolf Reik said, "If you cut yourself, it'll take quicker to heal the wound. "The scientists said their work might one day help us look younger. It could actually reverse the ageing process.
