What to do about lower face laxity, lifting and upper lip tightening? (Photo)

There are many ways to approach this problem and you have noted a few of them. We are familiar with the most widely used technologies and would suggest either Sofwave or SylfirmX. The Sofwave is ultrasound technology focused at to tighten the skin and also address skin texture issues. It is attractive because there is almost no downtime, and it is usually a "one and done" procedure. The SylfirmX is a form of bipolar radiofrequency treatment which requires a series of 3-5 treatments but can address both skin tightening and texture issues.

Although you’ve had a facelift recently, it appears that a secondary procedure, such as a deep plane, facelift, and or neck lift would be most appropriate for you. Deep plane allows us to address deeper structures, and create a more natural snatched look than traditional facelift procedures, if you’re interested in further discussion, please message me to set up a virtual consultation

What I see on the pictures (and an in person consultation, or at least zoom is essential for evaluation) is that your mid-face seems to droop, and you may have tried to correct this with filler. A mid-face lift might improve things greatly. They are tricky to get "right", but work for years if done well. We have had over 30 years experience with them, but find that only about 5% of surgeons are comfortable with them. At UCLA, I've taught these techniques to many specialty facial plastic fellows, and most do well with them.
