As the surgical sites heal, the healed tissue no longer requires such a profuse blood supply. With time, the hormones (cytokines) secreted - initially to recruit the blood supply - are no longer needed. In most healthy patients, at this time, the blood vessels shrink, swelling subsides, and the scars fade from pink to lighter in color. This process can take up to, and even over, a year to fully settle. Usually 70-80% of wound healing, scar maturation, and swelling subsides between 3-8 months. Every patient is different. Typically, the scars fade with time, even after a year.
Most patients scar well, but some are more problematic scar formers. If scars continue to be red, raised, or problematic after 1-3 months, non-surgical scar revision such as laser or steroid injection may be considered by your surgeon. Surgical scar revision is typically delayed for 8-12 months to allow the maturation process to declare itself.
