Why the Breast Is Not Like the Face: Volume, Spread and Safety

Face and breast are very different places to inject. This page is part of our guide to breast fillers.

The volume problem

A filler syringe usually holds around one millilitre. A noticeable breast increase involves volumes many times larger, often hundreds of millilitres per breast, meaning very large quantities of product. This raises costs, risks and the chance of complications.

Product spread

A soft, large organ allows injected gel to shift or spread with movement, gravity and pressure. Lumps, irregularities and migration are more likely. Unlike a cohesive implant, the material does not stay as a single defined object.

Difficulty correcting problems

With small amounts, a problem may be easy to treat. With large volumes, treatment is harder and may involve surgery. The material can be deep or dispersed, and not all fillers dissolve.

Interference with screening

Injected material can appear on mammograms and ultrasound, and may be mistaken for abnormalities or hide real ones. See fillers and screening.

Lack of long-term evidence

Compared with facial use, little long-term data exist on breast fillers, especially across years of screening and ageing.

Professional bodies' caution

Some professional bodies have expressed concerns about large-volume fillers in the breast. Some large-volume HA products once marketed for the breast have faced restrictions or withdrawal in some places.

Questions to ask

• How many millilitres would my treatment need?
• What happens if it forms lumps?
• How would it affect my mammograms?
