From what I have read, the best way is exercise and proper diet of course but also other ways are herbal forms such as gotu kola. It is the best I have heard. The website from herbal magic has a formula with a price tag. I think it is guaranteed to work though. I know the fat formulas do work because I have seen a friend go from huge to size 5. It is worth checking out www.herbalmagic.com.
If you can't afford the herbs, the trampoline is the best exercise for cellulite so get on one and bounce your way to fit. Lay on the floor after your bounce and put your feet up and massage your legs, it is eliminated easier that way. Drinking 8 glasses of water will eliminate a lot of toxins for you. Eating fresh pineapple will also eliminate fat. Eating fruit alone, on an empty stomach will digest in 20 minutes and take a lot of toxic waste with it. Vegetables will take 45 minutes, raw is best. Massage is a necessity to help rid cellulite. Rub any cream in the infected areas after bathing. Anything to help circulation will also help. The worst foods that add to cellulite are preservatives , dyes and fast foods, try to avoid. Eat low fat, as little dairy as possible.
Good luck and have patients. It took years to get it, it will take a while to get rid of it.
