How to treat cobra neck due to over aggressive liposuction 10yrs ago? Had facelift with no improvement (photos)

Sorry about your neck result. This often happens after liposuction where the platysma muscle bands show through the skin. If you clench your jaw to show your lower teeth, this activates the platysma muscle and makes the middle two edges of the muscle bands stick out through the skin.
Using botox can reduce the activity of the platysma muscle, but if you already see the bands when you are fully at rest (like in the photo), Botox will unlikely help to flatten out the bands.
The indentation in the center of the neck would provide for a nice sharp neck to chin (cervicomental) angle, if the two muscle bands were not sticking out lower than the center area.
During a consultation, I will use an analogy of wearing a dress shirt or sports coat and if the shirt or coat is unbuttoned, when I bend forward 90 degrees, the 2 edges of the shirt or coat hang straight down to the ground with the space between the shirt/coat edges appears to be indented.
If you button the shirt/coat, and lean forward, there won't be an indentation or at least significantly minimized between the two muscle bands because it is a continuous layer of platysma muscle from one side of the jaw to the other.
Not knowing how old you are or having the opportunity to examine you, I am not sure if you need additional skin removal to get the best results. In general, redraping the skin, meaning lifting up the skin then laying it back down and removing any excess skin on the sides gives the best results.
For younger patients under 35, their skin elasticity is naturally very good and the skin tends to contract without need for skin removal. Look at examples of liposuction where the skin appears to contract down without any loose skin. While for others who may have lost a significant amount of weight, they end up with loose skin which will unlikely contract down any further and will need some kind of skin removal surgery.
Hope that helps.

There are numerous non-surgical options available, and some can be used in combination to get best outcomes, but you would need a consultation with an expert. fillers help this alot we can add dilute radiesse however you need a platysmaplasty for the neck banding and morpheus + laser for the texture and tightening.

Some options for skin tightening include:

- Thermage radiofrequency to heat the skin, tighten it over time, and prevent the aging process
- Ultherapy high-intensity ultrasound to contract the muscle, tighten the face and neck, and prevent the aging process
- PDO NovaThreads or InstaLift threads for immediate lifting without surgery and long-term collagen production
- Sculptra injections for collagen production to areas of the face and neck with crepey skin or early sagging
- BTL Exilis Ultra, Venus Legacy, and Thermi250 for monthly collagen stimulation with facials
- ThermiRF, Renuvion (J Plasma), or Inmode BodyTite for internal heating and tightening with or without surgery
- Fillers (or facial implants) to contour the jawline and chin to improve the appearance of the neck
- Face lift / neck lift with fat grafting and fillers if you need a significant improvement​

​I would suggest getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer​​​​
