Hi, thank you for your question. I see two different issues which could be addressed:One, fullness under the chin, commonly referred as double chin, andTwo, horizontal lines of the neck. Since it doesn't appear that you have too much laxity (hanging, excess skin) of the neck, you should be a good candidate for Kybella.Kybella melts fat cells in the region under the chin and pulls the skin up. It is minimally uncomfortable procedure, done in the office and has minimal downtime.May require more then one treatment depending on your responce and how big the fat pad under your chin is. The horizontal lines of the neck could be addressed with either Botox injections, Dermal threads or maybe both. Please see qualified physician in your area.
