A hypertrophic scar is a thick, raised scar caused by increased formation of scar tissue. It generally stays within the boundaries of the original wound. A keloid can grow beyond those boundaries and is a different condition.
Skin type, location, tension, inflammation and individual predisposition can influence scar development. Redness or firmness early in healing does not automatically mean that a permanently hypertrophic scar will form.
Depending on the findings, options may include silicone products, pressure therapy, injections, laser treatment or surgical revision. The treatment and timing are chosen individually. Complete removal without creating a new scar, or a result that is certain to be invisible, cannot be promised.
