I’m getting orthodontic treatment now, but back then I didn’t know what the problem was and got chin filler for a retruded chin first. The feeling when I first got it was like... that feeling when those click-type hand warmers they sold at stationery stores when we were little harden. The effect lasted about 3 months, and I think it all disappeared. But when it was almost gone, I started getting acne on my chin. When I searched, there were a lot of people who got acne. For people who have a complex about their chin, I think trying it once wouldn’t be bad.
