After the liposuction, the superficial layer of adipose fat is undermined with a blunt-tip, 3-mm cannula (which is not connected to a vacuum pump). The breast ptosis is corrected by stimulating the controlled retraction of the incision scar, by undermining the superficial fat of the medial and the lateral upper areas of the breast; the maneuver tightens (retracts) the skin envelope of the breast. Procedurally, the liposuction-only breast reduction procedure concludes with the application of an elastic, foam-tape dressing that molds the reduced breast into its new shape, and lifts it higher upon the chest.[citation needed]
