As a wound heals scar tissue fills in the damaged places. While a scar may look quite dramatic after itâs first formed, over time its appearance, size and color naturally fade. On average, most scars can take 6 to 18 months to heal naturally. More severe scars can take years.
In addition, the normal healing process involves a period of skin contraction, which often peaks 4 to 6 weeks after the surgery. This may appear as a bumpiness or hardening of the scar. On the face, this change is nearly always temporary and the scar will soften and improve with time.
