Hi, I had a chin implant to replace the use of filler. It was meant to match. More or less the effect filler had on my chin and jaw. I did not ave a weak chin. But a little bit of filler helped to give it that very defined look. I did ask for subtle. I feel so different now. It’s not awful but I feel no like me. More masculine and really exaggerated. It’s not silicone. And I don’t know the size. It’s not yet been a year but do I need to wait that long. Or is it better than I’m thinking ?
