The goal of liposuction is to enhance the body and facial contours through the elimination of excess fatty tissue. The procedure permanently removes the unwanted fat cells, up to several liters of them. In this sense, the results of liposuction are permanent. You won't gain any new fat cells after your procedure. That said, it's important to maintain habits that support weight stability after you receive liposuction. Arguably, weight management through healthy eating and regular exercise is the primary way to enjoy prolonged effects from your body contouring procedure. Also, the aging process will inevitably, at some point, affect your physical appearance. This may not relate to your weight but to the ongoing decrease in tissue firmness and elasticity.
