What's the best way to improve my profile, specifically my jawline and chin? (Photos)

Based on the images provided you could potentially benefit from chin augmentation with either filler or a chin implant.  Chin filler is temporary and lasts about a year.   A chin implant is performed through a small submental incision and will provide permanent augmentation. 

When one desires an enhanced or stronger chin profile, two options include:  1. surgery using an anatomically appropriate solid chin implant, or 2. use of one of several injectable fillers.  The implant is permanent, the fIllers temporary.

A better set of facial photographs from the side angle are required to make a formal determination. Placement of a small  chin implant can augment the chin forward  to help  with facial balance and proportions, especially with respect to the projection of the nose. Chin implants are usually placed through a small incision underneath the chin under local anesthesia as an outpatient procedure which takes approximately 30 minutes. For many examples, please see the link and the video below

What you really are looking for is enhancements to your chin and jaw angles to create an overall jawline effect. The combination of a central chin implant combined with small vertical lengthening jaw angle implants is the most likely t provide the type of modest jawline changes you seek.

I do not see anything wrong with your profile. You have a very nice and defined jaw line and chin. I would not touch it!

Your concerns are completely reasonable. There are multiple options available to improve one's profile. From chin implant, genioplasty (cutting chin bone), injectables (more temporary), fat grafting, and liposuction.  All of these options alone or in combination can help improve the appearance of one's profile. Seek consultation with a board certified plastic surgeon experienced maxillofacial surgery and facial plastic surgery. Good luck!

Thank you for your photo. I think subtle enhancements will be able to provide you with the outcome you desire. A chin implant can be placed to improve the overall projection and look of your profile. Small jaw implants may also be placed to enhance the angles of your jawline and create a more defined look. Ask your surgeon to perform some before and after computer imaging of what they believe is realistic and if it is in line with the results you are seeking!

An additional photo from the front would be helpful to determine the best solutions for you.  Your chin does not appear to be "weak", however if you try temporary dermal fillers in this area, and like the result, you may be a candidate for a chin implant. If you are looking for more contour and definition in the jaw area, you may want to consider jaw augmentation, also involving implants.  Consult with a board certified facial plastic surgeon who is experienced in both procedures and who can show many before and after photos you like, with the type of results you are seeking.  Best,Dr. S.
