Is vaser - or any - lipo worth it for me? I'm 30, healthy, currently at a low bmi with around 12% body fat. For the past 2 years I've been anxious about by growing double chin. When looking straight ahead it is relatively okay, but as soon as I start to look the slightest bit down, the skin sags and bunches under the chin. I'm aware there are other reasons such as receeded chin, overbite, weak jaw etc. But here, would a a small amount of lipo benefit me? or am I paranoid?
