Which procedure could address my concerns with the least complications & scarring risk? (Photos)

It's difficult to say without the benefit of a formal evaluation. This is my expertise and a huge portion of my practice. Asymmetry is normal and expected. See an expert who does facial shaping with surgical and non surgical methods to get a comprehensive option. Best, Dr. Emer.

Thank you for your question and for provisioning photos. Mini facelifts are ideal for treating mild to moderate skin laxity and jowl formation. During this procedure, the jawline can be angulated, jowls reduced, and excess skin removed, while the remaining skin is tightened to create a refreshed and rejuvenated appearance.
When compared to a traditional facelift, mini facelifts are less invasive and can require a shorter recovery phase while providing results that may last for eight years or more in some patients. I recommend scheduling an in-person consultation with an experienced, board-certified facial plastic surgeon. They will be able to conduct a physical exam to determine the best procedure for you.

Keep this simple. A basic facelift done by a well respected surgeon who gets good results. I’m not a fan of fat injections. They do nothing but make your face swollen until the fat resorbs and waste money.
