(BlackDoctor.org) — Excessive scarring is the result of many factors, including extensive trauma to the tissues around a wound, the length of time that the wound is open before it heals, the location of the wound on the body, as well as skin color. People with higher quantities of skin pigmentation from melanin tend to make thicker and darker scars.
When more than enough scar tissue is formed following surgery or trauma, the scar is considered to be hypertrophic. Hypertrophic scarring is characterized by rapid growth in the first several month, accompanied by itching and skin darkening from excess inflammation. These types of scars generally shrink over time, but can leave unsightly skin deformities.
