Thank you for your question. Kybella is an excellent, non-surgical treatment to permanently destroy fat cells under the chin and jawline. I have successfully used it to treat patients in their 50's with excellent results. That said, every patient is different, and it's impossible to say whether or not you would be a good candidate for Kybella without assessing you in-person, or reviewing your photos. Generally speaking, I think Kybella works best for patients with mild or moderate fullness under their chins, and with good skin quality overall. Although Kybella does seem to slightly tighten the skin in treated areas, I generally don't recommend it for patients with significant loose skin or prominent vertical neck bands, as these can get worse after treatment. Kybella can be coupled with non-surgical skin tightening treatments like ThermiTight or Ultherapy if needed as well. I would recommend scheduling a consultation with a cosmetic dermatologist or plastic surgeon to discuss the best treatment options for you. Best of luck!
