You work hard to get yourself as toned as one of those bodies on the label of a package of health food. Except behind you are these dimples that won't go away, no matter what you do.

Cellulite, dimpling mainly on the back of the thighs, hips and behind, is fat. Those areas are a stubborn place for fat — relatively spongy, fibrous and less interactive with the blood supply — which means they're good for insulation and absorption of impact, but fat there doesn't go away as fast with exercise and diet.

Cellulite is only a menace because having it seems to upset the culturally romanticized view that silky smooth skin is a sign of youthfulness and health.

Even that is a misconception, considering that cellulite starts appearing at about age 12 to 14 — about the time of puberty — and has no more effect on overall health than any other fat, says the American Academy of Dermatologists.

Once it develops, its progress is individual. Because cellulite is fat, it can grow or shrink with the amount of fat you accumulate. And as humans age, their top layer of skin thins and cellulite can be more visible.

Cellulite becomes visible when the connective tissue breaks loose unevenly and allows the fat at those spots to expand, Wright said. "The part that's still connected becomes a valley, the part that's broken loose becomes a hill.

The frustrating part is that cellulite usually hangs on after all the other fat has gone away. That's when it drives people to doctors. Doctors say the U.S. Food and Drug Administration has approved treatment for the temporary removal of cellulite, but nothing for permanent removal.

• Exercise and a good diet: The No. 1 treatment is to maintain a good diet that reduces fat throughout your body. Wright notes that cellulite fat is the last fat the body loses.

• Treatments: Some creams may work temporarily, usually just because they tighten the skin, doctors say. But there's no way to reduce fat beneath the skin with cream on top of the skin, experts say.

• Endermologie: This treatment uses suction and rollers to reduce the appearance of cellulite. Wright said it has been shown to work for up to six months. However, regular treatments are needed, and can cost more than $100 each. The FDA has approved a specific Endermologie device, marketed by LPG Systems; make sure the person treating you isn't just shoving a rolling pin around your thighs.

Doctors don't consider cellulite a disorder. Many of those who sell remedies say cellulite results from a liver problem or toxins in the body. The FDA says none of those claims is true.

"Manufacturers usually claim a lot more than they can produce," said Dr. Thomas Francel, chief of plastic surgery at St. John's Mercy Medical Center.
