My chin was so stressful that I decided to get contouring injections earlier this year, and I went to the hospital that I found by selling my own products through a plastic surgery review app. He did it.. I should have stopped at that time. I heard that contour injections need to be shot several times to be effective, so did they get hit 2 or 3 times? After that, I didn't do it because I was a student, so the money was burdensome, but after that, my cheeks got sunken. Looking for filler...
