Believe it or not, this ugly looking fungus, called the reishi mushroom, is the main ingredient in a beauty treatment that is thought to slow down the ageing process.

Hot-shot TV presenter Fearne swears by this bizarre mega-mushroom range, which is produced by cult beauty brand 'Origins'.

While applying fungus to your face may sound a little crazy, mushrooms have been used for 4,000 years in Chinese medicine. Reishi mushrooms contain vitamins B,C and D which act as an antioxidant, halting free radicals which are thought to contribute to ageing.
