I was always worried about having a blunt chin, so I finally decided to get it last year , so I went to the hospital (the hospital just gave me factory treatment!) and they recommended 2 cc because my chin was so severe. So I put in 2 cc and was satisfied at first, but when I looked in the mirror, I saw my chin. It's slim, but it still looks too flat in the picture , so I went to the hospital about 2 months later and had 1cc inserted. I wanted it to be sharper, so I went for retouch a week later and added 1cc more. After about 6 months, it felt like I had lost a lot. Added about 1cc again! To summarize, 1. I had about 5cc of filler in my chin for a year. 2. I am satisfied now that I have a chin, but when I take pictures, my face still looks round, possibly due to a bone problem. 3. But people around me say my chin is too sharp. There are still no side effects, especially. I didn't have any, but the stiffness in my chin was quite severe for a while, and if I don't put on makeup, the tip of my chin is still red, and when I lie down to sleep, I sometimes feel the foreign body sensation that is typical of fillers. I don't know if it's okay to continue getting filler, or if I should consider surgery. Then, that's it!
