Botox to correct my chin pebbles and injected into my Masseter Muscle? Costs and How often? (photo)

You will need approximately 8-10 units of Botox for your chin dimpling and 25-30 units of Botox for each masseter muscle injection.  You do not want to over inject either area.  The injections will need to be repeated every 4 months and the cost of injections will depend upon the cost per unit charged for Botox.  Having said that, the photos that you have provided of the chin injection patient and the jaw reduction patient are very misleading.  Botox alone will not alter the appearance of your jawline to that significant of a degree and although Botox will stop the chin dimpling at rest and with slight motion, in those photos the pre injection photo is in full motion and the post injection photo is at rest.

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  I frequently perform botox injections into the masseter for this indication.  It is very effective in the right patients and should be performed every 4-6 months.   The most important aspect is to find a surgeon you are
comfortable with. I recommend that you seek consultation with a qualified
board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.
