Caffeine + diet/exercise = results
Caffeine on it's own = just moving fat from one fat cell to another
Caffeine is the most widely known lipolytic chemical (lipolytic is a chemical that "break down" fat). However, as everybody knows coffee or caffeine itself does not help you lose weight. Why is that?
The answer is simple: caffeine does indeed break down triglycerides (fat) inside fat cells and stimulates the fat cell to release those triglycerides into the circulation. However, if fat is not oxidised (burned) for energy in muscles or other organs, it will inevitably be absorbed by another fat cell and stored there.
So unless you burn the fat with exercise or diet, that fat will end up back into a fat cell somewhere in the body. In this case, all that caffeine will help you achieve, is to move fat from one fat cell to another.
On the other hand, if you do eat less and exercise more, the fat released due to caffeine, exercise, diet or all of the above, will be oxidised into carbon dioxide and water and expelled from the body via the lungs and urine & sweat, respectively. This is why most diet pills contain caffeine: it stimulates the expulsion of fat from fat cells. But the rest (i.e. burning the expelled fat) is your job.
So in summary: caffeine + diet + exercise = results. Caffeine on it's own = just nerves ;)
Caffeine cream + exercise / diet = spot fat reduction
Caffeine cream on it's own = reduced effectiveness
On the other hand, caffeine applied locally, as in anti-cellulite creams that contain caffeine, is effective in reducing local fat, because it does help expell the fat from fat cells in that SPECIFIC area where it is applied, and thereby reduces local fat and cellulite.
Of course, if you don't exercise / diet when you apply the caffeine-containing cellulite cream, the released fat will end up in the blood circulation and it will be redeposited somewhere else in the body(as we explained above). In fact, some of it will actually be redeposited on the same area.
That's why you need to exercise / diet when you use a cellulite cream. If you don't, you just reduce the effectiveness of the cream and waste some of your money down the drain.
On the other hand, if you exercise / diet and use an anti-cellulite cream (with or without caffeine) on a specific area, you can reduce cellulite and local fat from that specific area. This is called spot fat reduction and it is impossible by just exercising a specific muscle on that area.
If you are going to bathe on caffeine cream, just drink coffee instead
Finally, it does not really make sense to apply a caffeine / cellulite cream all over your body, because then you do not achieve a localised effect and the result of the whole body application is equivalent to... just drinking coffee, i.e. pointless, as we described on the first paragraph of this article. So be smart and use an anti-cellulite cream locally - on one or two body areas max - don't waste money on slapping it all over your body!
