There is usually a reason for why people get a dimpled look in their chin. Sometimes, it is due to the structure of your jawline and dental anatomy- especially if you find that it takes some "effort" to close your mouth (people like this tend to be more comfortable with their mouths open, at rest.) If there's a structural issue here, then even if you "relax" the chin muscles (aka mentalis) with Botox (6-10 units), that won't necessarily fix the problem! It's easy to do, but not necessarily what you need. The profile may still bother you. It would be helpful to see a photo of you smiling with your mouth open. Filler may be more helpful to build up the chin area; or a plastic surgeon may recommend a chin implant. Be well and good luck. - Estee Williams MD
