Videos of a beautician performing the surgical procedure liposuction at a beauty salon have been shared with the BBC, as several women complained that the treatment left them injured and disfigured.

Luxury Medical Aesthetics & Academy, based in Clapham, south-west London, is running a one-day training course for beauticians billed as a “fat reduction masterclass”.

It is not illegal in the UK for a non-physician to perform surgery unless they are claiming to be a surgeon and have the client’s consent.

BBC’s File on 4 contacted salon owners Daria and Monika Wisniewska about the complaints, but they did not respond and blocked messages.

Sarah Guy, a beautician from South Wales, paid £1,500 to Luxury Medical Aesthetics & Academy for a “one-day fat reduction masterclass” after being inspired by the company’s before-and-after photos on Instagram.

Ms Guy, 34, was told she would be trained in a new type of lipolysis.

Lipolysis usually refers to injections where chemicals break down the fat cells and the fat is naturally removed by the lymphatic system and liver.

When Ms Guy arrived she was shown into the salon where she said there was “blood splattered on the walls” and “there were gauze clothes lying around that still had the previous person’s blood on them”.

During the training course she was told she could take videos. But what she saw later left her so worried that she shared these things with the BBC.

Dalvi Hamzah, consultant plastic surgeon and member of the Joint Council for Cosmetic Practitioners (JCCP), said basic hygiene protocols were not being followed in salons, increasing the risk of infection and putting lives at risk.

“This is a list of all the disasters that are waiting to happen here,” he said.

While watching the first model undergo a liposuction procedure, Mr Hamzah said he noticed that the client was at high risk of infection, if not septicemia, and could potentially have major complications following the procedure.

Ashton Collins of Save Face, a voluntary register of accredited beauty practitioners, is supporting some women who have complained of complications and injury after fat reduction treatments at Luxury Medical Aesthetics.

Ms Collins told the BBC that all the women were told they were receiving non-surgical fat dissolving treatment, not liposuction.

She said: “It’s only when they’re numbed and they see the actual device coming out and they feel it poking into their skin, do they realize what’s really happening. ?”

Save Face said a woman was hospitalized after suffering “injuries” to her internal organs.

Despite refusing to practice on a model, Sarah Guy passed the training course and was awarded a certificate from Luxury Medical Esthetics.

Ms Guy complained to the company that the procedure they were teaching was unsafe.

He said his messages were ignored and he found himself blocked from contacting the company on Instagram.

The company has declined to respond to requests from the BBC.
