Although it depends on the size of the graft and the care during healing, a skin graft typically takes 2 to 4 weeks to completely heal, according to the University of Minnesota Medical Center. Healing depends on the care of the dressing, swelling and sutures.
A skin graft is a procedure to replace damaged or missing skin with healthy skin from another part of the body, according to the University of Minnesota Medical Center. Patients need to care for both the skin graft and the site where skin was removed by changing bandages 4 to 7 days after the procedure. The bandage should be kept dry and clean, and the skin area should be elevated. Patients are expected to rest at home for at least a week following the procedure. Pain medications are typically prescribed.
