I have been performing nonsurgical chin augmentations with injectable volumizing fillers for about fifteen years. These days,Voluma XC, is my injectable volumizer of preference for this purpose. In most cases 1 cc (occasionally 1.5-2 cc) is sufficient to effect a visible, immediate and gratifying improvement--the kind that evokes and immediate "Wow!" response when the person compares the before and after profile photos.Nonsurgical chin augmentation is not to be left to the hands of novice injectors trained to treat simple smile lines with ordinary fillers. It is an advanced injection technique that should be peformed by a board certified aesthetic physician with experience and expertise in this technqiue. Be sure to ask to see his/her before and after photos. Best of luck to you.
