The latest non-surgical weight loss procedure that's taking Hollywood by storm promises incredible results after just one hour-long session.

The procedure that promises you'll drop a dress size and get rid of your muffin tops, love handles and spare tyres is here.

American plastic surgeon and body contouring specialist Dr Mark Jewell helped develop Liposonix, the non-surgical alternative to liposuction using ultrasound to eliminate those stubborn fat deposits that exercise won't budge.

• New age cellulite treatment
• Wrinkle-free without botox
• Magnetic beauty therapy

"This is revolutionary. It heats the tissue and destroys fat cells," Dr Jewell said.

"I see this as an evolving technology - possibly even for the double chin we will have something shortly."

Patients see permanent results within four to twelve weeks, and clinical trials in the US found some lose up to six centimetres around the waist, while 90 per cent lose at least 2.5 cm.

According to Jeff Nardoci, vice president of global marketing for Liposonix "you can really go anywhere where the fat is."

He says that "in Europe its been used on the outer thigh, on what a lot of women will refer to as my 'saddle bag'."

Melbourne cosmetic specialist Dr Tass Tasiopoulos is the first in Australia to offer the new treatment which has just received TGA approval.

The lunchtime procedure, painless for most, costs upwards of $1800 depending on how much treatment is required.

Unsuitable for obese patients, it's designed to iron out and contour those who have a spare inch to pinch.

Ultrasound technology has long been used in surgery on things like kidney stones. This time it's heating and permanently destroying fat cells.

Possible side effects are minor swelling and bruising.

"There's no anaesthetic, no scarring, there's no down time and after the procedure, (a patient) will be able to continue with her normal day. She could even go to the gym tomorrow. It's very much a non-invasive, non-surgical procedure," Dr Tasiopoulos said.
