How many units of Botox will I need for jaw reduction? It's my first ever Botox so I want to go slowly (Photo)

Without examining you it is difficult to be certain but generally 30 units per side is a good starting dose. In terms of the other symptoms, if they are related to grinding or clenching of the jaw then masseter reduction may help. Gcp

Hello, Thank you for your question. For women, a softer, less prominent jawline is usually considered to be more feminine, and therefore, more attractive. The Botox, injected in both sides of the jaw, will selectively relax the masseter in the days following your injection, gradually making it less prominent and square. The width of your jawline will slowly narrow, transforming your facial shape into more of an oval or heart. Typically patients receive 50-70 units for masseters, based on the strength of these muscles. Upon your assessment, your skilled and qualified injector will be able to provide you with a quote and will determine if you're a good candidate for this treatment. Take care. 

I start with 25-30 units per side and reevaluate 2-4 weeks later.  Often up to 50 units of botox per side is needed.  In korea they often do even more.  Best, Dr. Emer.

Botox is a great option for shaping and contouring the face.  Injection of the masseter muscles should help relieve grinding of the teeth at night but may or may not have effects on tension that extends down to you shoulder.  As is always the case, there is a range of dosages that may be required.  Starting conservatively and working your way up may be helpful.  Too large a dose can lead to a sunken-in look. 

Generally, we use 20-40 units of Botox for each side of the masseter depending on the size and strength of the muscle.
