i got a porex chin implant around one year ago, but i need more projection in my chin. is it possible to add another chin implant on top of the already existing one? i have one titanium bolt in the middle of the implant holding it in place. also, i had my nose done around 2 years ago and it is still not what i want, however i do notice it changing still and improving slowly. is there anything i can do to speed up the process? i know that it hasnt stopped changing yet, just need it to speed up.
