The main muscle in the chin is called the mentalis muscle.  Although this is a very small muscle, it can become quite strong with repeated contraction, and for some people, it is not unusual to carry a lot of tension in the lower part of the face unconsciously.  A repeated and ongoing contraction of the mentalis muscle of the chin leads to a dimpling condition called "pebble chin".  Hyperactivity of the mentalis muscle makes the chin look very uneven, rough and bumpy, thus the name “pebble chin.”  Very small doses of Botox Cosmetic allows for a nice relaxation of the mentalis muscle with an overall softening of the chin. Technique is extremely important when determining how many units of Botox are required for this technique so make certain that your practitioner is knowledgeable about facial anatomy before attempting the procedure.
