Detailed answer

Hypertrophic scars are characterized by their raised and thick appearance. They form when there is an overproduction of collagen during the healing process, resulting in a raised scar that stays within the boundaries of the original wound. Hypertrophic scars can be red, itchy, and they may gradually fade over time. On the other hand, contracture scars are characterized by the tightening of the skin and deeper tissues. These scars can restrict movement and may occur after burns or large wounds. Contracture scars are caused by the contraction of collagen fibers during healing, which can cause the skin and underlying tissues to tighten. If severe, contracture scars can lead to functional limitations or deformities.
