NEW YORK (CBS 2) — Cellulite can show up on people of any size and it is usually unwelcomed.

There are many products and cosmetic procedures that promise to diminish cellulite; from lotions and creams to lasers or liposuction. Now there is one more tool to add to the list of fat fighters.

CBS 2’s Mary Calvi reports about a new device that was recently approved by the FDA. It does the work of two different machines.

Lisa Castronovo is fit and trim, but she can’t seem to get rid of cellulite on the back of her legs.

“No matter how much you work out it, just starts to form,” said Castronovo.

A new technology called “Reaction” is the first device that combines existing therapies to treat cellulite and fat, and tighten the skin.

“A better overall result with fewer treatments,” said Dr. Matthew Schulman of the Mount Sinai School of Medicine.

The treatment uses traditional radio frequency energy to heat the skin, and vacuum therapy to increase blood flow to the area.

“Heating will cause the collagen to shorten and tighten the skin. Or it causes a controlled injury to the fat and causes the fat to disappear,” said Schulman.

There is very little discomfort with the treatment, but there can be some bruising afterwards.

“It just felt like someone was giving me a massage with really hot heat,” said Castronovo.

According to doctors, it usually takes a few visits to see the effects. A single maintenance treatment once or twice a year afterwards is suggested.

Insurance won’t cover procedures like this because it’s cosmetic. It will leave a dent in your wallet, costing about $2,500 for a six-week treatment.

For patients like Castronovo, it is worth it.

“I feel a lot better,” she said.
