Looking at your face is all about proportions. If you look at the upper, middle, and lower 1/3s of your face, you are short on the middle and lower 1/3s. Very common with insufficient growth in your upper jaw, which is a big part of what sets the growth of your lower jaw. Based on your profile, I suspect you had orthodontic treatment that pushed out your lower front teeth and pulled back on your upper front teeth (possibly with removing some teeth). This creates a concavity from your nose to your chin. If you go by the numbers, your chin is in a good position front to back, but the angle between upper lip and nose is about 100 degrees, the ideal being 95. So it is subtle by the numbers, but looking at your nose, you have less tip support which is going to change the relation from nose to upper lip. At the end of the day, everything above is fluff, the most important question is what is that you see that you don't like? If it is the shape of the nose, you would be. a good candidate for a rhinoplasty, if it is the shape of the jawline/position of the chin, a genioplasty may be a good option. If it is the entire relation of your lower face and the lack of distance from your chin to your neck (especially if you snore or have sleep apnea), double jaw surgery with or without rhinoplasty is probably the most predictable way to change the entire balance of your face.
