Does RF Cavitation Work to Remove Stubborn Fat?

I started dieting and working out so that i lose some extra weight i carry.I went to a beauty salon though to help the stubborn fat to go away easier,along with my cellulite(plus if my stubborn fat was going away faster i wouldn't have to diet too much and lose all of my breasts) .They suggested i go for a method called "rf and cavitation".do you think it will work?or is it a freud? Any dangers?any alternatives apart from lipo? Thank very much for you time
