"I have used fillers off and on for 36 years.  Collagen, Restylane, Radiesse, Juvederm,  Voluma, and more to fill acne scars and laser burn scars above my lip caused by a quack.  I've always had at least a modicum of improvement and sometimes even  success with these various fillers.  However, when I finally decided after two years of research to go ahead and have Bellafill injected to one area of my face where there are acne scars, I wound up with absolutely no visible or palpable evidence that Bellafill was even in my face. A total rip-off. Utterly useless material. In fact, the acne scars are even more evident after this bizarre injection episode.  Just because the FDA approves something doesn't mean it has any merit."
