Would chin lipo work for me or would it leave me hanging skin? I am trying to decide between Kybella or chin lipo.

Both Kybella or neck liposuction are good options and will improve the double chin. It depends on your lifestyle and personality which would be better for you. 
Kybella is best for patients that:
1)  Do not want surgery 
2)  Are not surgical candidates 
3)  Not willing to wear a compression dressing around the face for 1 week 
4)  Patient-  The results of Kybella will take months
Kybella take 1-3 treatments every 6 weeks.  Patient will develop swelling and possible bruising after each injection that may last a few days.  The benefit of Kybella is each treatment is quick and completed in the office. However, some patients need more than one treatment to get desired results. 
Neck Liposuction is best for patients that:
1)  Want a single treatment 
2)  One recovery time-  Downtime for neck liposuction require wearing a wrap around face for 1 week. 3)  Less painful 
4)  Quicker results 
5)  Cost is a concern
Neck liposuction is a quick surgical procedure that can be complete while the patient is awake.  It cost around the same price a Kybella and can be less in patients with heavier necks.  The single recovery of neck liposuction may be a better option for some patients.

Hello Twoboystwogirls,
It’s a pleasure to answer your questions! I would recommend you getting a NeckTite procedure, to eliminate the excess fat (double chin) and tighten the sagging skin around your neck, and achieve long-lasting and natural-looking results. NeckTite is a minimally-invasive, advanced contouring device, FDA-approved and readily available nowadays. With NeckTite, patients who would prefer to avoid surgery and general anesthesia, can remove excess neck fat without leaving behind saggy, wrinkly skin. Recovery time required for this procedure is remarkably short (24-48 hours), and also pain-free, relative to traditional lipolysis methods. NeckTite is a leading-edge contouring solution that helps patients achieve results similar to a necklift without excisional surgery. This scalpel-free, and scarless skin treatment is typically performed in the office, under local anesthesia. Using radio-frequency (RF) technology, the surgeon places a small probe beneath the skin that heats the tissues causing them to contract and tighten. Request an in-person consultation with an experienced plastic surgeon to assess your candidacy for NeckTite and discuss your specific needs and cosmetic goals. Best regards! Dr. De La Cruz.
