What can I do to get rid of this small hole new my chin? (Photos)

Melaniebrowne,
Depressed areas like this appear to be from underlying scar tissue that is tethering the superficial tissues down toward the deeper tissues.  A combination treatment of first, breaking up the scar tissue with a technique called subcision and second, using a dermal filler to add volume to the area would be my initial recommendation.  Resurfacing of the entire peri-oral area with a laser would help bring a more youthful appearance to the entire region.  A formal, in person evaluation always gives clinicians a better chance to evaluate your condition and provide the best individualized treatments.   Cheers- Dr. Nesiba

You can treat this condition with lasers, microneedling, fillers, RF, PRP and Micro-fat grafting.  Be sure to consult with a facial aesthetic specialist. Best Regards,  Dr. Weiss

This can be improved with laser spot treatment, fillers, microneedling/prp and subcision to help texture and blending. I recommend getting a formal evaluation with a scarring expert. Best, Dr. Emer

This small indentation appears amenable to fillers.  I would use a product such as Restylane or Restylane Lyft to fill it.  You may also benefit from some Botox or Dysport in the chin to relax the chin muscle.
