Can a Too Tight Face Lift Improve with Time?

Generally speaking, it can take 6 to 12 months to completely heal after a facelift procedure. I would strongly recommend speaking with your surgeon or his/her clinical team to discuss your concerns further.

The tightness and tissue thickening
that you describe following facelift surgery is usually related to
swelling.  This response varies
from patient to patient and depends on the surgical technique and wound healing
characteristics of the patient. 
The majority of swelling usually resolves in about two weeks following
facelift surgery. At this point, most patients can return to work and resume
normal activities.  In most cases,
total resolution takes about three months.  In rare cases, swelling may persist for up to a year
following surgery.

It’s important to realize that more
aggressive facelift procedures cause more swelling, which can last for longer
periods of time.  Elevation of the head and decreased salt intake may help decrease
swelling after surgery.  Swelling
is normal following surgery, but persistent swelling should be evaluated by
your surgeon.

3 weeks is still relatively early in healing process after your surgery.  There are still irritated nerves and tight muscles.  Be patient and continue to follow up with your surgeon as directed.
