The nipple is the protruding part of the breast that sits on the flatter pigmented area known as the areola. The nipple carries the milk ducts and has an important role in breast feeding and as such can change following episodes of breast feeding and also ageing.
Just as with the areolar, the size and colour of the nipple varies significantly between individuals. The key is for a proportional size in terms of both projection and the base diameter of the nipple in relation to both the areolar and overall breast size.
Nipple size can be reduced by nipple reduction surgery. Increases in projection can be achieved non-surgically with placement of dermal fillers such as Juvederm Voluma. Surgical enhancement is achieved by grafting either ear cartilage or skin and fat from another part of the body to achieve more projection.
