22 y/o Male - how can I improve my jawline/ face structure?

The only way to achieve such a jawline effect as you have shown is with a custom jawline implant design. The effects of such implants are best reflected in thinner faces just like the examples you have shown.

Your options are fillers, A chin implant or sliding genioplasty.

I suggest having multiple in person consultations with local board-certified plastic surgeons in your area. The sliding genioplasty may be more frequently performed by oral surgeons.

Fillers have the advantage of being adjustable each time you have treatment but they are temporary and you will need ongoing treatments.This means that the treatments can be tailored yo your liking and you can try different Providers.

To get results like the pictures you’ve shown you would also need a substantial amount of filler.

One syringe is not going to do the job in your case.

For someone who knows they want this taken care of an implant is probably the way to go.

For those who are opposed to implants or some of the drawbacks that come with them a sliding genioplasty may seem like a better option.

Best,

the key is to recognize that your lower jaw is genetically underdeveloped and so augmenting the back, middle and chin/genioplasty, will change the contours. The actual result depends upon tissue thickness but is very positive in all situations
