How Long Does the Swelling Supposed to Last After a Face Lift and Neck Lift?

Some element of swelling can be present for many months after a facelift procedure, but most of the swelling will be gone within the first month after surgery. The first week is the worst, and with each successive week, the amount of swelling should continue to decline, although this might fluctuate on a day to day basis.
Keeping the head elevated, especially while sleeping, and using a compression garment of some kind can both be helpful to reduce swelling.
All the best,

While for most patients the majority of the
swelling after a facelift resolves after two weeks, with further minor swelling
lasting for another few months, each patient is different and swelling may
resolve at a different rate depending on the patient’s individual healing rate,
the type of surgery done, after care, and more. I would encourage your mother
to visit her surgeon for a follow-up visit to make sure that everything is
healing properly. I hope this helps.

I'm sorry to hear that your mom is still experiencing
discomfort after her facelift. Although it's uncommon for these symptoms to
persist for 4 months after surgery, it does happen. It doesn't sound like your
mom is at risk of any dangerous complications, but the symptoms you're
describing are probably worth a call or visit to her surgeon's office. The
staff there is more familiar with her case and can recommend different
therapeutic options to help ease her symptoms. Best of luck!
