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.
In the videos one of the owners, Daria Wisniewska, can be seen injecting a solution into a woman’s chin who has agreed to be a model for the procedure.
Ms Wisniewska then uses a scalpel to make a small hole and inserts a long cannula attached to a suction machine on the floor and begins to suck out fat.
Ms Guy saw the same method being used on another model’s chin, and a third woman’s stomach.
Consultant plastic surgeon and member of the Joint Council for Cosmetic Practitioners (JCCP), Dalvi Humzah, said that basic hygiene protocols were not being followed in the salon, increasing the risk of infection and putting lives at risk.
“It's a catalogue of disasters all waiting to happen here,” he said.
When watching the first model have her liposuction procedure Mr Humzah said he noted that the client had a high risk of infection, if not septicaemia, and potentially could have major complications after this procedure.
