No, it doesn’t work. If it worked, just like if weight loss pill X worked, it would be studied by scientists and heralded around the world. It’s a scam where by ordering the free pills you agree to a monthly recurring shipment and astronomical charge, and it’s very hard and time consuming to unsubscribe, let alone get your money back.
There is simply no way a topical cream would help get rid of cellulite. At best the cream may cause the skin to tighten up thus giving the appearance of no cellulite, but you would need to reapply it constantly to keep up the charade. The wikipedia article has more information about cellulite including some of the theorized causes. I am particularly interested about the analysis done comparing men to women which finds that women may be more susceptible to developing cellulite due to the way our fat cells grow and the way fat is stored on our bodies in general. Until we can understand why it exists, we cannot truly create a solution. I’m afraid you’ll just have to get used to it being a part of you.
