forgotten the name of a weight loss product

hey everyone
a while ago i read a beauty article on bh and it was kinda promoting this weight loss wrap thing were u rub the product on ur belly or thighs and than wrap this.. thing around them for about an hour and it reduces ur belly or thighs by a couple of centimetres. ive totally forgotten wat this product is called but i really want to try it coz one of the bh article writers told us in that article about her experience with it and said that it actually works. im really interested in this product and if anyone can remember the name it would be really helpful
thnx xx.
