What can I do to make my chin appear smooth when smiling? (Photos)

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

Botox to the mentalis can certainly correct the peau d'orange or "golfball" like texture of the chin. If the positioning of the lower lip is changing, it means the injector is also injecting fibers of the depressor labii inferioris. That should be correctable with a change in injection technique. The dimpling you dislike on your chin is due to the pull of the underlying muscles, and not because of volume loss so I think neurotoxins, and not fillers, are the best way to correct the problem.
