What is a scar?
Scarring is the process by which wounds are repaired. Damage to the deeper layer of the skin, the dermis, is required to produce a scar. Damage to only the epidermis, the most superficial layer of skin, will not always produce a scar. Scars produce a structural change in the deeper layers of the skin which is perceived as an alteration in the architecture of the normal surface features. It is not just a change in skin color.
What are the different types of scars?
There is only one type of scar. The appearance of a scar depends on the nature of the wound that produced the damage, the anatomical location of the wound, and a variety of genetic factors that are different for each individual.
A defective healing process can result in a keloid, an unsightly, itchy, thick, red, knobby bump that often continues to enlarge over time. Keloids often are larger than the margins of the original wound.
