Hello!! I agree with Mazikeen, I think getting a facelift/pony lift may be too invasive for someone young. Perhaps acculift may help with some of the sagging. Acculift uses a laser to tighten the face instead of more invasive methods.
As for zygoma reduction, I’m 2 weeks post-op from my surgery with Dr. Kirk at Namu. He did a really good job with making my face symmetrical with zygoma reduction and fat grafting. Pricing might be higher than the other clinics you’ve contacted since those seem more local than Namu. If you’d like I can PM my photos
