As we embrace the first days of spring, I wanted to reveal the biggest secret that will be on the beach this summer.

A ton of those smoking-hot bodies soon to adorn the best beach on the New Jersey shore and Paradise pool are turning now to mesotherapy – a natural body contouring treatment – to achieve that ultra masculine and feminine silhouette we love to love so much in July.

“Mesotherapy is a technique where medication is injected into the mesoderm layer of fat in specific desired areas,” said Dr. Neil Rosen of Preventive Medicine of Monmouth. “The medication used is completely safe and naturally found in the body; we just use it in a very concentrated form.”

It’s vanity’s secret weapon.

Based on individual requirements, the doctor selects a mesotherapy formula that, when injected into the “problem” area slowly diffuses into the fat and breaks it down.

The number of treatments required varies depending on body type and personal aesthetic goals. For the average person, the results last for about 12 months when combined with exercise and a decent diet. Then, a patient goes for easy maintenance “touch ups.”

Mesotherapy was invented in 1952 by Dr. Michel Pistor. Today, 50,000 physicians worldwide offer mesotherapy treatments for a variety of medical issues. About 2,000 of the doctors are in the U.S.

The French Academy of Medicine recognized mesotherapy as an “inherent part of traditional medicine” in 1987. The FDA is conducting its first mesotherapy body contouring clinical trials, according to a recent statement by the American Society of Plastic Surgeons.

I know of almost 20 area men and women who have chosen mesotherapy – also called Lypolysis and Lipodissolve – instead of scary liposuction. Dr. Rosen has “hundreds of patients” in the greater Asbury Park and shore area.

“I would never let anyone cut me open unless there was no other option for my health,” said one Asbury Park male meso lover. “Liposuction should be a last resort. Mesotherapy is the perfect alternative for me.”

The treatment works best on people who have fat pockets to be eliminated around the stomach, flanks, arms, thighs, eyes, back and chin. It has been reported that Britney Spears, Demi Moore, Jennifer Aniston, Matt Damon and many other bold-faced names rely on mesotherapy treatments.

“Mesotherapy does not traumatize the body like surgery does,” said Dr. Rosen. “There is no scar tissue, residual effects or down time post-treatment.”

If figuring out what cosmetic procedures people have had was an Olympic sport, I would be on the cover of a Wheaties Box. Mesotherapy great because it is so subtle even a trained eye has difficulty telling that a person has undergone treatments.

And that makes for a great summer secret.
