My weak chin has bothered me my entire life and I just assumed there was nothing I could do about it. But not only is there something that can be done, the new implant styles are a great improvment over prior methods, so I'm so glad I waited. It's really pretty extraordinary how changing your chin can change so much about your appearance. For years, I thought I had a large nose when in fact I really just had a weak chin.
Before the surgery, I went on several consultations armed with a list of questions and chose the doctor who spent an hour explaining the procedure to me and put me in touch with a patient he'd just performed the same procedure on. And his work is amazing -- I can't believe the difference. It was only one week ago, and I'm back at work, slightly swollen but feeling quite good. What I didn't anticipate is how the "wings" of the implant would greatly reduce the jowls I was developing -- I look 10 years younger and that wasn't even the goal of the surgery!
You need to do your research and go with a doctor who has experience in this particular procedure, which is true of any plastic surgery procedure. I also recommend the inicision under the chin -- you can't see it, and there's much less risk of nerve damage and infection.
