You might have thought that copper was just for plumbing pipes, and used to make the coins in your purse, but now this mighty metal has become a key ingredient in some of the latest beauty youth-boosting products. Powerful antioxidants in copper help it to protect your skin against free radical damage. It also contains antimicrobial properties to help kill bacteria and prevent in inflammatory reactions. And it’s well known for its wound- healing abilities too. Leading skincare expert Dr Howard Murad rates copper as one of the most effective ingredients for regenerating the skin. ‘Copper peptides have been shown to reduce inflammation and promote collagen and elastin production, therefore helping reduce the appearance of lines and wrinkles and improving skin firmness,’ he says.
