For first-time attendees of Rachel Neuman's "wrap and lose" parties, the proof is in the packet.
The Central Florida woman hosts gatherings during which she says thighs, arms and stomachs can be tightened and toned in 45 minutes with no need for exercise or dieting.
Neuman is a distributor for It Works!, a company that sells packets of herbal wraps infused with a lotion of natural ingredients that it says tightens and smoothens saggy skin. The wraps are placed on problem areas and secured with cling wrap.
"As soon as this goes onto your skin, your skin immediately begins to absorb that lotion," Neuman said.
"I took the leap of faith. I spent the $25 to try it out, and it took away the area on my thighs diet and exercise would not have moved all these years," she said.
As a mom on a budget, Neuman says she couldn't afford luxuries such as the wraps, so she decided to help her habit by selling them.
Now, she hosts the "wrap and lose" parties to sell and distribute the It Works! packets. Hostesses earn free wraps -- and attendees hope to leave with a little less.
After a treatment, "the results continue to progress for the next three days," Neuman says.
Fox medical correspondent Dr. Jo Giovinco says you're not losing weight with the wraps but simply displacing the water around your skin's cells.
"I wouldn't expect long term benefits from it," Giovinco said. "It may give you a short term benefit, good if you were going to the beach or you want to fit into a wedding dress."
"It's a common misconception that this is water loss. In fact, you do need to drink a lot of water for this process to happen in your body," she said.
Giovinco says the wraps could be good for your skin, but she also offers a word of caution.
"Just make sure that it's not wrapped too tightly for too long a period of time. You don't want to get to the point where you're overheating or perhaps constricting a blood vessel or causing a clot of some sort," Giovinco said.
Said first-time "wrap and lose" party attendee Gloria Swiger: "So now that I tried it, I see what they're talking about."
