Chin filler for dimples done 6 weeks ago is rock hard and migrated to gums. (photos)

It is unlikely the filler migrated. However, I recommend following up with your injector. If necessary, the filler can be reversed with hyaluronidase. Hope this helps. 

Your story and the timeline suggest that you developed a granuloma, very likely biofilm related. I have personally found the injection of proper concentrations of an anti-inflammatory agent and the administration of appropriate oral antibiotics (and occasionally the injection of hyaluronidase) are sufficient to lead to the complete disappearance of the type of rock hard nodule you describe. Nonsurgical chin augmentation and lip augmentation are advanced injection techniques that should not be left to the hands of novice, medspa-type injectors accustomed to injecting simple Juvederm or Restylane into ordinary smile lines. So as an aside, I would strongly urge you now and going forward to seek consultation and treatment by a board certified aesthetic physician with experience and expertise and of course make sure to ask to see his/her personal before and after photos of any areas you wish treated. Best of luck to you. 

Thank you for your question! It is unlikely the filler migrated. However, I recommend following up with your injector. If necessary, the filler can be reversed with hyaluronidase. Best of luck!
