Can plexr firm the neck area? (Photo)

"A combination approach would give the most improvement. Nonsurgical options such as Kybella, PDO NovaThreads, and Ultherapy do well in combination for skin tightening, but the results are mild compared to surgical options.

I would recommend a VASER Hi-Definition Liposuction with ThermiRF, Renuvion (J Plasma) and InMode BodyTite to contour and tighten the chin and neck. A neck lift can be performed at the same time, if you're a good candidate. I suggest seeing a board-certified cosmetic dermatologist to develop a personalized treatment plan that works for you. Best, Dr. Emer.​"

Thanks for your question and posting pictures.  We see this regularly in our office.  On younger people, it is mostly caused by looking down at electronic devices.   If you have suborn fat under your chin, you may consider KYBELLA.It is difficult to treat these lines with filler.  Our best option for wrinkles in this area is bulk heating of the skin.  We use a radio frequency device called Pelleve.  It is a very pleasant 15 minute procedure that feels like a warm rock massage.  It gently warms the skin and hold it at the target temperature for 3-5 minutes.  This causes the underlying collagen to contract.  Your body recognizes the sub-dermal injury and responds with additional collagen production.
