Does Botox to the Chin Area to Get Rid of Pebbles Eventually Atrophy the Mentalis Muscle?

Botox works very well for Pebbly chin in small doses (5-10 units). Botox injections in any area develop permanence over time.Usually after 1-2 years of repeated injections, the underlying wrinkle producing muscles become atrophied and weaker. At this point you would require less botox or less often to produce the same improvement of the wrinkles.

Having Botox treatments (around 5 units to the chin) to the mentalis shouldn't have any effect on the masseters, which are in an entirely different area. Have an assessment and treatment with a well-trained and experienced provider to get your best results.
