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

​Treatment for chin dimpling ("pebble chin" or "orange peel") is Botox injected into the mentalis muscle. This typically gives great improvement to the appearance of the chin. Results take about 1 to 2 weeks​. I suggest getting a formal evaluation with a board-certified cosmetic dermatologist. Best, Dr. Emer​

A pebbly appearance or dimples of the chin is a common aesthetic concern with aging. Fortunately, these problems are quite easily treated with the use of microdroplets of a neuromodulator, such as Botox, Dysport or Xeomin. With repeated treatments over time, as with treating all other muscles of facial expression in this way the mentalis chin muscle does indeed atrophy a bit, so that further treatments down the road typically require even less material to achieve the desired results. 

Over the past fifteen years, I have found that prior volumization of the chin, i.e. nonsurgical chin augmentation, using a volumizing filler, such as Radiesse or Radiesse combined with Perlane L, another volumizing agent, yields both immediate as well as more sustained improvement and smoothing of the chin--especially when followed immediately by the above-mentioned injections of neuromodulators.

  The pebbled appearance of the chin can be improved with 10 units of Botox.  Over time, the pebbled appearance may become less noticeable and less Botox may be needed.

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.
