A pebbly appearance upon movement of the chin or the presence of dimples within the chin at rest typically relate to hyperactivity of the mentalis (chin) muscles with movement, in the former case, and with increased resting muscle tension in the latter. In either case, relaxing the muscles with a few droplets of a neuromodulator (Botox, Dysport or Xeomin) can be extremely helpful in smoothing these two types of problems. Should the dimples persist despite treatment, performing a nonsurgical chin augmentation using a volumizing filler (my choice in my Upper East Side Manhattan practice for this purpose being Voluma XC and Emervel Volume, in my Israel satellite facility where a far greater number of regulatory agency approved volumizers are available) can be extremely helpful for smoothing the irregularities that persist at rest.
