Hypertrophic Scar

A hypertrophic scar is a raised, thickened area of fibrous tissue that develops at the site of skin injury or a surgical incision when the body produces excess collagen during healing. These scars remain confined to the original wound borders and are often red, firm, and may be itchy or tender, typically becoming more noticeable in the weeks to months after the injury.

Risk factors for hypertrophic scarring include wound tension, infection, delayed healing, and certain skin types, and many scars will improve gradually over time. Management can include prevention and conservative measures such as silicone sheeting, pressure therapy, and topical or injected corticosteroids, as well as laser treatments or surgical scar revision for persistent or symptomatic scars, often combined with postoperative strategies to reduce recurrence.
