How Long Does Botox in the Masseter Muscle/jawline Really Last?

April 8, 2011
Asked By:Unoq

I only had 15 units per side 4 wks ago & it "worked" far too well! My doc says it'll wear off in 3-6 months, many Realself docs have stated 4-6, but I've heard reports that botox for jaw reshaping lasts way longer than in the forehead, i.e. 9-12 months! Some even say it's permanent (!!!) Going by averages, how long will it be before jaw botox actually begins to expire, and from there, when can one expect to be back to their pre-botoxed state - if ever!? :S
