Want to get rid of a pudgy chin in a jiffy? Rub a caffeine-rich cellulite cream along the entire jawline. How does it work? Caffeine, being a diuretic, will suck out all excess fluids and reduce puffiness. The effect will only be noticeable for three or four hours but that’s long enough to parade around a party or get through a hot date. Just make sure this stuff goes nowhere near your eyes!
