Chin Implant too big & makes my face look too long? (Photos)

I would recommend doing research on a genioplasty. It is more versatile than an implant, and will create a more balanced profile, while adding length and definition to your jawline. There is a decent stop off between your jawline and chin, which can be made more fluid with a genioplasty.

Dear Jasminer12,
I understand your concern. However, without a proper assessment, it would be difficult to determine what went wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

Hello. Yes, unfortunately, your facial proportions have a chin appearance that is not suitable for your proportions. You can ask your doctor about the dimensions of your chin implant. He will tell you what material and size it is. It is a very good idea to replace it with a smaller one. I’m the only triple board-certified facial plastic surgeon all around Europe. I’m just focused on this issue. I am a doctor who goes to almost every country in the world and explains my techniques to important doctors with the seminar invitations I receive, so I am definitely the only doctor who can perform your operation very comfortably and successfully. You can get more detailed information about me, ask all questions about your case and sending your photos to my assistants at the number on my profile (+90 539 204 40 90). You can also book an online consultation and discuss your problems with me. With all respect.

Hi Jasmine!
Suppose the objective is to correct or replace your current implant with another "better" one. In that case, the key to achieving the look you expect is to utilize a custom-made implant that is exclusively designed for you.
Thinking in terms of small, medium, or large sizes alone might only make your current dissatisfaction worst.
You'd want to spend time examining the shape, horizontal and vertical lengths, and, more importantly, your particular likes and dislikes.
To minimize most problems in fit, style, and look, first, we would need to order you a CT scan of your chin and jaw area to see what it is possible to do for you with clarity and certainty.
The last thing you'd want to do is go through another unpleasant procedure.
Depending on the type of implant you have now, there is a strong possibility that your current implant has made a "groove" or indentation in your bone's surface, and merely using another standard or off-the-shelf implant could bring additional issues down the road.
You do have options. To make sure you look as beautiful as you want to look, we would need to spend a considerable amount of time understanding your exact likes and dislikes, i.e., a more oval, round, or softer look.
A custom implant that is exclusively designed for you will likely guarantee better results.
Perhaps you think your chin implant is a bit too square, and you see it as too "big"?
Could it be that you feel as though the transition of your chin and your jowls (Jaw area) is too abrupt?
From your profile view, your chin does not look too long. For this and other reasons, you'd want to start with a CT scan so we can review and present you with all of your options.
I hope that helps, and if you have other questions, don't be shy and ask away!
