Would a chin liposuction alone (no implant) make my weak chin and jaw look better? (Photo)

A combination of treatments may be needed to get the results you want. Neck liposuction is a great option for patients with good skin elasticity and excess fat in the neck and around the jawline. Liposuction is effective at removing this excess fat and stimulating the skin to contract over time to create improved angulation and definition along the jawline. You may decide a chin implant would help provide more projection. I recommend seeing an expert for a consultation. I hope this helps!

You do not need to have a chin implant to have improvement in your neck.  If you would like to take things simple and have improvement without major lift procedure and proper chin micro lipo by very experienced surgeon would give you enough improvement.   It is all matter of what you want not what a surgeon wants.  

Thank you for your question and posting appropriate pictures. You seem to be a good candidate for laser liposuction (SmartLipo) of your neck and fat grafting to your chin  as you need minimal value added to your chin without a need for a chin implant. You would need a consult for precise recommendations.
