When we do liposuction these days, we perform a variation called tumescent liposuction. This means that the area to be treated is first injected with a special fluid that contains lidocaine to numb pain and adrenalin to control bleeding. The lidocaine will prevent you from feeling any pain during the procedure. The fluid also helps to break up the fat so that it can be more easily aspirated through the cannulas, which are the small straws that vacuum away the fat. Inserting a laser into the treatment area not only breaks up the fat to facilitate removal but also tightens the skin. Thus, laser liposuction is less aggressive than traditional liposuction because the fat is quite easy to remove. You may feel sore and swollen after your procedure. This can be controlled with icing and painkillers. At 21, you are an adult and laser liposuction is perfectly safe for you. However, you will lose inches, not pounds. Liposuction is a body-contouring technique, not a weight-loss method. Consulting with a board-certified dermatologist will give you a better idea of what you can expect during and from your laser lipo procedure.
