Scars form when there is direct damage to the deeper layer of the skin. Recreation of collagen occurs during the healing process which is responsible for the creation of a scar. In general, scars are associated with a loss of integrity of the skin anywhere within the body. The final healing process of an open wound is a scar. Inflammatory processes and wound healing include epithelization, wound contraction, and collagen formation. Thicker scars include keloid and hypertrophic scars. Hypertrophic scars can be surgically corrected, however keloids if excised again, will create even worse scarring.
Scars form as a reaction to injury of the deeper layer of the skin called the dermis. When the dermis is injured cells called fibroplasts deposit collagen into the area of the damage to mend the tissues thus forming a scar. Scars have different qualities based on the surrounding tissue and the amount of tension on the scar. Scars typically have a different texture and color than the surrounding tissue. Scars have approximately 70% of the strength of intact skin.
