Videos of a beautician performing surgical procedure liposuction in a beauty salon have been shared with the BBC after several women complained they were left injured and disfigured by the treatment. Luxury Medical Aesthetics and Academy based in Clapham, south-west London, have been running one day training courses for beauticians advertised as a "fat reduction masterclass". In the UK it is not illegal for a non-medic to perform surgery as long as they’re not claiming to be a surgeon and have consent from the client.

The BBC's File on 4 contacted salon owners Daria and Monika Wisniewska about the complaints but they have not responded and blocked the messages. Sarah Guy, a beautician from South Wales, paid £1,500 to Luxury Medical Aesthetics and Academy for a "one day fat reduction masterclass" after being impressed with the company’s before and after photographs on Instagram. Ms Guy, 34, was told she was going to be trained up in a new type of Lipolysis.

Lipolysis usually refers to injections where chemicals break up fat cells and the fat is removed naturally by the lymphatic system and the liver. When Ms Guy arrived she was shown into the salon where she said there “was blood splatter up the walls” and “gauze swabs lying around that had still got blood on from the previous person”. During the training course she was told she could take videos.

But afterwards she was so worried by what she’d seen, she shared these with the BBC. File on 4 investigates the cosm.
