Liposuction is generally used in an attempt to change the body's shape. Weight loss from liposuction appears to be of a short term nature with little long term effect. After a few months fat typically returns and redistributes. Liposuction does not help obesity related metabolic disorders like insulin resistance. It can also be used to remove excess fat in the chronic medical condition lymphedema.
Finally, there’s the so-called scarless lift. Women who are seeking a mild lift but are dead set against leaving scars anywhere on their breasts may opt for a technique that uses a network of dissolving surgical threads inserted through tiny incisions along the collar bone, guided under the breast tissue, and then anchored to the collar bone, to create an internal bra of sorts. Scar tissue forms around the threads, theoretically providing support to lift the nipple.
