Most people report little discomfort in the days after lip augmentation. However, grafts and flaps usually involve more pain during recovery, and a longer recovery period, than lip injections.
Injections: Most people return to normal, public activities within a couple of days of an injection procedure. Bruising and swelling may last as long as a week.
Grafts: People often wait between one and two weeks after graft procedures before returning to their normal routine. During that recovery time, they may experience some problems with drooling. Grafting also may leave the lips feeling unnaturally stiff for 2 to 3 months after the procedure. Any non-dissolving stitches may be removed about 7-10 days after the procedure.
