Very Weak Chin & Thick Lower Lip?

Photos would really be necessary to provide you with the best advice. In general, a chin implant is simple procedure that can yield fantastic improvements for a weak chin. However, if there is an issue with your jaw, that would need to be addressed separately by a board certified maxillofacial surgeon. From here, I would recommend a consult with an experienced facial plastic surgeon. He/she will be able to assess your needs, and may use computer imaging software to give you an idea of how the final result of surgery may appear if you are a good candidate for a chin augmentation. He/she will also be able to provide you with advice on your lower lip. I hope this helps, and best of luck! 

Without an exam or even photos your question cannot be answered. However, Here is some helpful information to see if you are a good candidate for a chin implant augmentation procedure:

Candidates for Chin Augmentation -
Patients whose chin profiles are weak but have normally functioning jaws are candidates for Chin Augmentation. Many of these candidates have used injectable fillers in the past to strengthen the protrusion of their chins, but are looking for a permanent solution. If you are one of these patients, then you are a likely candidate for chin augmentation.

Intended Result
Chin augmentation most often is used to restore balance to the face due to a weak chin (under-projecting in profile). This disproportion of facial structure—having a small chin—tends to make the nose look larger and results in a poor jaw/neckline. As it doesn’t support the neck skin, often it causes skin to hang down from the upper neck and can lead eventually to a “turkey waddle” deformity. Chin implants can also create a wider, stronger chin. They can also be used to lengthen the face slightly.

The augmentation is performed  with a sterile, biologically inert implant (such as silicone or Medpor) which is placed over the bone of the lower jaw so it feels like your real chin and not like a separate implant.

A wide range of chin implants are available, depending on the patient’s needs and goals. These implants vary in their dimensions and are made of different materials. The proper selection of the correct size and type of implant by your plastic surgeon is critical for you to achieve the look you want.

It is very important to select a highly-skilled, board-certified plastic surgeon, or ENT or Oral Surgeon experienced in this procedure, to aid you in selecting the implants and insertion methods that will give you the best possible result.

If you like the look you get when you protrude your jaw, it is certainly possible that a chin implant might help. An in-person exam or photos would be helpful to take the decision-making process to the next step.  See your friendly neighborhood PS for more information.
