There is no specific age restriction on having body contouring surgery, but as you are not legally an adult, this is something you would obviously need to consider along with your parents as their consent would be necessary. Liposuction is major surgery. Recovery can be lengthy and painful. There are risks involved and potential complications. At the age of sixteen, most young women are not physically mature. Is your weight stable, or are you still growing?. Please know that liposuction surgery is a body sculpting technique, not a weight loss tool. When performed on an individual whose weight is not under control and stable, liposuction can result in disproportionality when the areas of the body not treated continue to expand as additional fat is deposited into fat tissue.Emotional maturity is also a factor. Dealing with complications, pain, disappointing results or unmet expectations can be difficult for an adult, even more so for a child.Liposuction can be performed on a sixteen year old, but I would recommend nutritional counseling and patience first. Find a well qualified surgeon certified by the American Board of Plastic Surgery who will take these issues into account and keep your best interests at heart. Together you can decide when you are ready.
