Hypertrophic scar prevention

A hypertrophic scar forms when the skin produces extra scar tissue within the original injury. Wound tension, irritation, infection, delayed closure, and individual healing patterns can influence the result. Prevention lowers avoidable irritation but cannot control every factor, including how your skin responds after surgery, injury, burns, or inflammation.

Follow the wound-care instructions you were given, keep the area clean, and do not pull away scabs or pick at sutures. Once the surface has fully closed, a clinician may recommend silicone-based care or gentle support for the scar. Limit rubbing and stretching, protect the area from sunlight, and mention any previous thick scars before a planned procedure. Early steroid injection into the skin or another treatment may be considered if thickening begins.

Arrange a review if a healing wound becomes increasingly red, hot, swollen, painful, or starts draining. Also seek advice when a scar becomes firm, itchy, raised, or tight, especially if it interferes with movement. Fever, wound separation, or rapidly spreading redness should be assessed promptly rather than managed with over-the-counter products alone.

Ask when scar care should begin, which products are suitable for your closed wound, and how to protect the area during exercise or work. Tell your clinician about prior raised scars and ask whether your planned procedure can be closed or positioned to reduce tension.
