I got a short chin filler because I was worried about my short chin. The one I received was supposed to last for 6 months. It's been a year since I got a short chin filler, but it seems to have disappeared pretty quickly up to about 6 months, but it does n't disappear at all, and it seems that a little filler remains for more than a year. My friends also said that it seemed to be a little longer than my chin before I hit it! I want to get hit again, but it hurts so much that I 'm thinking about it. Also, I got quite a few pimples on my chin, probably because of the filler!
