Will 0.5ml be enough chin filler for subtle improvement?

Chins usually require at least 1, up to 3 syringes to get improvement as its quite a wide area and the filler is placed deep on top of the bone. Half syringes are too subtle and only work well in areas like the lips or undereyes.

Hi there! 0.5 cc of filler, depending on the type, can be enough. But, in order to stretch the chin, you often need more than you would think. Good products are Juvederm Voluma, Restalyne Lyft, and my most preferred, Radiesse. The first two can be dissolved whereas the latter in theory cannot be. I like Radiesse because it lasts more than 12 months and stimulates collagen to form in the area leading to a solid result. Hope this helps!
