Are neuromodulators (such as Botox®) useful for facial feminization?
Botoxing the masseter muscle may also help with slimming the jawline, but this would again, only provide a minimal change and would occur only at the angles of the mandible. If you have a particularly wide or tall chin, fillers would be ineffective in this location.
When delivered in the correct location, Botox can help lift the lateral eyebrow, but this is also a minor effect and would not provide as big of a change as a surgical brow lift.
Neuromodulators (such as Botox) are not frequently used as the only tool for facial feminization, however, they can help improve the results of other FFS procedures and they can produce minor effects that feminize the face.
