Hi, I had a chin implant procedure last year to help fix my receding chin. However, the implant was placed too low and therefore made my face too long - I have a large head so this isn't ideal I had a revision in Jan and now the implant is better but still seems to be quite low. Additionally, the implant moves up and down on the right side of my face with any pressure I’m wondering if being able to move a chin implant is normal and whether this would warrant another revision? TIA
