Bruising to some extent after surgery is inevitable. Usually the worst of the bruising is out by day 5, then fades to yellow before slowly disappearing. It is unusual to have any significant bruising 2 weeks after surgery. It is not uncommon for the area that has been operated on to look a slightly different colour in certain lights for several weeks after surgery. This is caused by deeper blood pigment and/or new blood vessel formation in the deeper skin as the tissues heal. Stubborn bruises and discolouration can be effectively treated with a pulsed dye laser.
