Here's the bottom line, and it isn't pretty.
Doctors say that more than 80 percent of women have cellulite, those dimpled pockets of fat that most often accumulate in the thighs, buttocks and hips.
Doctors believe cellulite may be nature's way of ensuring women have enough stored energy to bear children, which may explain why even thin women or those who work out religiously still may have it.
Biological imperative or not, most women can't stand the sight of cellulite. American women spend billions of dollars a year on slimming and cellulite-fighting products and procedures.
Shop Etc. magazine's beauty director Amy Keller gave "Good Morning America" the lowdown on some of the many creams, injectibles, spa wraps, suction therapy, and even "butticals" -- that's a facial for the fanny -- that say they fight cellulite:
Many rub-on creams contain caffeine, which experts say can constrict blood vessels and draw moisture out the skin, resulting in a temporary tightening effect.
They can take a few months to work, but they're the cheapest option.
Bliss Fatgirl Slim Cream, costs $25.
Avon Super Shape Cream, costs $16.50.
Suction Slimmers -- Endermologie
Mechanical massage devices consist of a vacuum hose and two rollers, which lift and knead the skin. Like any other deep massage, the treatment can be somewhat painful, depending on the level of suction.
For maximum effectiveness, about 14 treatments are recommended over a seven-week period, followed by monthly maintenance visits. Without follow-up, cellulite reappears after one month or two months.
The cost, which can be more than $100 per session, isn't covered by insurance.
Endermologie came to the United States from France more than a decade ago and is approved by the Food and Drug Administration.
Endermologie makes the skin appear smoother possibly by stimulating blood flow and lymphatic drainage or by thickening collagen, though no one can say for sure.
Critics, like the American Society of Plastic Surgeons, say it is of "unproven medical value."
It is most likely to work if you are under 55 and no more than 20 percent over your ideal body weight.
Wellbox, $1,595 -- The at-home version. Dermatologists say the at-home version is almost as effective as salon treatments, but you have to keep up the maintenance. It is expensive but FDA approved, and you'll get better results than with creams.
Spa treatment, $100 to $125 per session -- Need eight to 10 sessions to start then monthly maintenance.
Medi-Sculpt Machine, $150 per thigh per session -- This is an even newer suction treatment that hasn't been approved yet. Supposed to stimulate fat-burning by breaking up the connective tissues.
Use ingredients like seaweed extracts that penetrate more thoroughly because of the spa wrap's warmth and compression.
Experts say you'll lose, but it's water, not fat, and the effects only last until you're hydrated again.
Recommend for the quick fix. You'll lose about an inch of water, but it only works for a few hours. Seaweed is diuretic, so muds and seaweeds will have similar effects.
Ahava Pure Mud costs $25.
Aquatanica Marine Mineral Body Wrap costs $22.50.
