Botox didn’t wear off after 8 months. Will it laser forever? (Photo)

Botox will relax the target muscle for ~3-4 months, after which time the masseter will begin to regain its function. During the 3-4 months it was relaxed, it was not able to contract or "work out" so it began shrinking in size. This atrophy will not reverse immediately once it regains its activity but will happen gradually over months. If you are still concerned about the slim appearance of your masseters, chewing gum and eating chewing intensive food will help accelerate the masseter gaining mass once again.

usually Botox's effect is completely gone after 6 months, especially if its a brand like Allergan or dysport.However sometimes brands imported from other countries have more preservatives and can last up to 8-9 months. Nevertheless, the effect will resolve and you will have more movement. muscle hypertrophy will come back if you clinch your teeth again just like when you exercise any other muscle in the body.

The Botox will have worn off and will not last forever. Your muscles will take time to get back to where they were as they are muscles and increase in size with use. They do not pop back when the Botox wears off. Keep chewing and you will be fine.
