Sofwave vs Ultherapy for 61 year old female - which is better for face tightening? (Photo)

Why play around with expensive, supposedly "next big thing," here-today-gone-tomorrow gizmos that have neither stood the test of time nor have any hard science to back up the heavy marketing hype and social media promotion.
At least from the photo provided, you would be wise to consult with an experienced, board certified cosmetic dermatologist filler expert to discuss. An appropriate HA volumizing filler, for example, properly injected by an expert in the area of the cheeks would not only preserve your cheek fat, but would likely improve the hollowed under-eye areas, as well as secondarily Improve the smile lines.
An appropriate HA lifting filler properly injected around the mouth would straighten the angles of the mouth, as well as eliminating the marionette lines drooping.
And, while without a profile view, I cannot assess the jawline, I would guess that an appropriate HA contouring filler injected along the jawline would better define and straighten the jawline and diminish any jowls there.
What's more, unlike the smoke and mirrors gizmos, the results of HA filler treatments in the hands of an expert typically yields on-the-spot results and engenders little to no significant post-treatment downtime.
Hope this helps and saves you lots of money, time and disappointment. Best of luck and happy holidays..
