What procedures can I do to fix the laxity and lack of firmness in my face? (Photos)

You may be a good candidate for an elastic lift (see the link below). You can get this procedure done under local (it is not threads).

Best of luck !

Hi from Istanbul! To address the laxity and lack of firmness in your face, a temporal midface lift could be a suitable and lasting option. This procedure involves a small incision in the hair-bearing area and lifts the midface, temple, and brow together as a cohesive unit. This approach not only rejuvenates your appearance by creating a balanced and refreshed look but also helps achieve slimmer cheeks. Hope this helps!

Hyaluronidase does not wreck the skin. It simply removes old funky hyaluronic acid filler. Certainly "a bit of vitrase" can't be blamed for your facial laxity consistent with your age. One other hand, don't let a surgeon who can't bother to clean their eye glasses tell you need a facelift--you don't.
