Best cellulite reducing exercises/creams?

I'm young and relatively thin but i still have cellulite.
I've tried depriving myself of all 'junk' foods and saturated fats but its near to impossible to do that all my life.
Anyone got any advise for stuff that works?! Whether it be exercises, creams (as a teenager I have a low budget, very), or just anything thats helped you!!

please any advise would be appreiciated
