What are the best non-surgical procedures for 60+ woman with sagging jowls?

Thank you for your question. Unfortunately, it is difficult to determine what treatments might work for you without at least a photo or two. I offer some different options in non-surgical skin tightening for patients that want to firm up the skin without going under the knife. Thermage and Ultherapy are two procedures that work deep into the dermal structure to constrict tissue and produce more collagen for skin that is noticeably tighter and smoother. 
Thermage uses radiofrequency energy to heat the lower dermal layers. The heat causes tissue to tighten and stimulates the body to produce more collagen. Ultherapy works in a similar fashion, but uses ultrasound energy instead of radiofrequency. The device also delivers the heating more deeply, for even more dramatic results for most patients. 
Both of these procedures are done in the office without the need for anesthesia. There is no downtime afterward. Results appear over time and can last for many months or even years in some cases. Make sure you work with a board-certified dermatologist to ensure you procedure is safe and you achieve the best possible results. 

Laxity along the jawline is common. There are non-surgical procedures available to improve the jawline and neck. Endolift Laser is a remarkable procedure using a fiber placed beneath the skin to tighten skin and smooth out fat. This in conjunction with PDO threads to reposition fallen tissue and stimulate collagen are ideal.

Morpheus 8 is a non-invasive skin and soft tissue tightening treatment that is consistently amazing in our patients. We use the Morpheus to exact fractional induced RF into the skin or tissue in order to tighten collagen and stimulate contraction of the tissue. For acne scars, it is quite useful to build collagen in patients who have atrophic scars but is not very productive for ice-pick scars which require TCA Cross. For tissue tightening, Morpheus is ideal for the face and neck and we often combine it with CO2 laser or Ultherapy to further enhance results. Chemical peels and skin resurfacing should be done at least 5 to 7 days after, but can be performed earlier, depending on treatment severity. Avoid exfoliating skin treatments before Morpheus and expect a period of 2-4 weeks for skin contraction to set in.
