16 Neurotoxin Injection for Lip Lift

Indications

A small improvement in the visible pink lip can be achieved by the use of BoNTA in some patients. This can be used to enhance the upper and/or lower lips.

Anatomic Considerations

The orbicularis oris muscle is the sphincter that surrounds the mouth. The pull of the muscle is toward the center; therefore, weakening this pull will allow the upper lip elevators and the lower lip depressors to increase their pull on the lips. This increased pull will result in more visible pink lip and a slight “lip lift.”

Injection Technique

Botulinum toxin is injected at the base of the philtrum at the vermillion border. The corresponding location of the lower lip may also be injected. Approximately 1 to 2 BU is used for each injection. (Because of the increased zone of effect of Dysport, the authors prefer to use Botox in this area.)
