does running on an elliptical machine help get rid of cellulite on thighs?

Hi! I am 20 years old and about 105 lbs. But I have realized I have a lil bit more "bumpiness" on the back of my thighs, right underneath my bottom. And I want to get rid of it. But I HATE running on tredmills because it hurts my chest. But I absolutely LOVE elliptical machines. Does exercising on an elliptical machine help with the probelm I have with cellulite on the back of my thighs? Does it have the same impact as running on a tredmill?

P.S.
The cellulite on the back of my thighs isn't that bad, but I like to wear shorts and skirts a lot, since I do live in sunny San Diego. So I tend to get a little self-conscience when wearing them. I feel like everyone is staring at my cellulite! lol
