You’ve seen the girls at the beach in the floss bathing suits. Don’t lie: You’re thinking about trying it.

There’s just one big problem — your ass.

Minimize the situation with a Resculpting Body Treatment for your tush.

Famed New York aesthetician Tracie Martyn just brought her trademarked — and much touted — service to Lapis Spa in the Fontainebleau. It’s like a face-lift for your derriere or whatever other part needs a boost (face, tummy, thighs).

The secret: the Resculptor. The futuristic machine uses a mild current to stimulate skin, increase circulation, and reduce cellulite. The process is followed by an application of Shakti body cream, a fancy firming lotion made of natural and organic ingredients.

Skeptics take note: Your skin will look tighter after one treatment.

Strange. Butt true.

Available at Lapis Spa, 4441 Collins Avenue, Miami Beach (305-674-4772 or fontainebleau.com). For more information, go to traciemartyn.com.
