Well Sandy, chin implants when done properly bring out that area you mentioned between the chin and bottom lip slightly. If that area remains a problem to you injecting a filler there such as Juvederm is always an option. Personally I only feel comfortable recommending plastic surgeons I know instead of basing them off others reviews. Are you open to traveling at all for your chin implant surgery?
Fortunately for you, wherever and by whomever does your chin augmentation, there are plenty of competent plastic surgeons who can perform this procedure. Chin implants are one of the easiest procedures to do. That doesn't mean that every doctor is good at it, but it does mean that you're more likely to get a desirable result and higher satisfaction rate. There are literally hundreds of models and styles of chin implants on the market today. Certainly there is one that meets your needs. Have you checked out any of the plastic surgeons in your area to see which ones have experience with chin implants? Be sure to find before and after pictures of chin implants from the plastic surgeons you are thinking about. You want to make sure the doctor you choose does indeed have experience performing chin augmentation surgery.
“One popular new plastic surgery technique is called lip grafting, or "fat recycling" wherein fat cells are removed from one part of your body that is too large, such as your buttocks, and injected into your lips; people will then be literally kissing ass.”
