The procedure can be done under local anesthetic and the same day you can go home. Nipples that are large (due to genetics or breast feeding) or those that are inverted or retracted can be resized and reshaped as you desire with little to no visible scarring. Larger nipples can be trimmed to appear more natural and less aged. Flat or inverted nipples can be enhance or corrected by either releasing scar tissue at the base of the nipple or by inserting a small cartilage stent.
