What characterizes a hypertrophic scar?

A hypertrophic scar is characterized as being raised and firm, a result of excessive collagen deposition during the healing process. Unlike keloid scars, hypertrophic scars do not extend beyond the boundaries of the original wound; they remain confined to the area of the initial injury. This distinction is essential because it affects treatment approaches and patient management.

The raised nature of hypertrophic scars can occur due to various factors, including the type of skin, location of the wound, and individual healing processes. They are typically red or purple in color and may be itchy or uncomfortable, but their limitation to the original wound area is a key identifier that distinguishes them from other types of scars, such as keloids, which can become much larger than the initial injury site.

Understanding this characterization is vital for effective wound management, as hypertrophic scars may improve over time or require interventions such as pressure therapy, silicone gel sheets, or corticosteroid injections to help flatten the scar and reduce symptoms.
