How do I improve the side profile of my chin? (Photo)

The side profile photographs demonstrates a weak and recessive chin profile, for which a chin implant can improve significantly.  Chin implants are composed of Silastic, and are manufactured in a large  variety sizes and shapes. The implants are usually placed through a small incision underneath the chin under local anesthesia as an outpatient surgical procedure.  In our practice, we use Implantech chin implants for the last 25 years with an excellent success rate.  For more information, diagrams of the implants, and many before and after examples, please see the link and the video below

The most effective method for bringing the chin forward with some elongation is a sliding genioplasty. This is particularly relevant in someone who is very young. Once you move the bone and it heals, there are no future problems that can ever occur. A deep labiomental fold is a problem in any chin augmentation where the chin comes forward. It may not worsen due to the elongation of the chin but may also require fat grafting to reduce it.

There is definitely room for improvement here, especially considering the photos that indicate your ideal. i would recommend a chin implant. BUT, I think some sculpting of the nose is also  a good idea, again considering the ideals  you have proffered.
