There is no one right answer to your question as there are many different scars related to the type of skin and its texture of the patient undergoing surgery. Some people are prone to darkening of their pigment after surgery and others develop red blood vessels around the scar. Some can get overhealing where collagen of their body continues to be produced and deposited in the scar excessively which produces a raised, sometimes painful, scar which may be a hypertrophic scar or keloid. Some people's scars spread, possibly related to an inborn error of collagen and some become inverted as a groove. The scar may have a different shape depending on the shape, depth and diameter of the wound and its relationship to the location of cosmetic structures such as the lip and jaw. The scar may be a line, curve, zig-zag, L-shaped, T-shaped, S-shaped, Z-shaped, H-shaped and other unusual patterns are needed as well. The scar will usually be red for many months. Ultimately, after about 18 months, the body produces maximum maturity of the scar and in the best scenario, it becomes smoother, flatter, and a thin white line. Unsightly scars can be treated, often by Fraxel laser for resurfacing, massage, dressings, V-beam laser for long-standing redness so contact your doctor if you are unhappy.
