How to fix my side profile?

To make a determination about a chin implant and improvement of the side profile requires side profile photographs presented in a chin neutral position looking straight ahead. Chin implants are manufactured in a large variety of sizes and shapes for patients who have a weak and recessive chin profile. Chin augmentation helps with the side profile for better facial balance and proportions. For more information, and many examples, please see the link and the video below

D3D4, your photos though interesting are not very helpful in answering your questions. See an experienced plastic surgeon that specializes in "only faces"; make sure you like their photos. See the video and good luck!

 Hi, I have performed many facial shaping procedures, including Chin Augmentation with dermal fillers or silastic chin implants, for over 30 years.  From the photos, your chin is very weak.  When the chin is weak, this creates an imbalance making the nose appear larger, the mid face top heavy, the lower face looks short, de-emphasizes the lips and allows early formation of a "double chin".  
 Proper placement of a silastic chin implant adds forward projection to the chin thereby creating harmony and balance to the lower face.  Using the same incision, liposuction can be performed to reduce the fat and further shape the neck.  Excess skin, from below the chin, can also be removed through the same incision.  
 I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for chin implant surgery.  You should consider chin implant surgery before doing any of the other procedures that you mentioned as none of these will add forward projection to the chin and as such can't correct the weak chin.Hope this helps
