Hyaluronic acid fillers
What hyaluronic acid fillers are, how they work, their usual approved uses and why those approvals do not extend to breast enlargement.
Regulatory position
The FDA advises against using dermal fillers or other injectable fillers to increase breast size. Serious complications from inappropriate body injections can include infection, persistent pain, tissue damage, scarring, deformity and potentially life-threatening events.
What dermal fillers are
Dermal fillers are injectable products used for certain approved aesthetic indications, depending on the product and the jurisdiction. Different products have different compositions, behaviours and licensed uses.
Why breast use is different
An approval for facial use does not imply suitability for injection into the breasts. The breast is a different anatomical site with different considerations, and the consequences of complications can be more difficult to manage. Because of this, breast filler injections should not be advertised or presented as a routine breast-enlargement service.
