Generally, the most prominent bruising appears within the first 48 to 72 hours after the surgery and then gradually starts to fade. While some people may notice a significant reduction in bruising within the first week, it's common for the discoloration to persist for another week or 2. Residual bruising and swelling, though, can last for several months. The extent and duration of bruising can vary based on several factors including the individual's healing capacity, the complexity of the surgery, the surgeon's techniques, and how closely post-operative care instructions are followed.
