How can hypertrophic scarring be prevented?

• A. Apply pressure garments as prescribed
• B. Ice packs continuously
• C. Sun exposure
• D. Vigorous daily massage

Answer: (A)

Applying pressure garments as prescribed helps prevent hypertrophic scarring by providing constant, uniform external pressure that influences scar formation as it heals. Hypertrophic scars arise from excess collagen deposition and disorganized fibers; the sustained pressure reduces blood flow to the scar, lowers fibroblast activity and collagen synthesis, and promotes more organized remodeling. This leads to flattening of the scar, reduced height, and better color and pliability as the scar matures. Pressure garments are used after the wound has closed and epithelialized, typically for many months to a year or more, under medical guidance. In contrast, ice packs offer only temporary vasoconstriction and do not alter scar progression; sun exposure can worsen scar pigment and appearance; vigorous daily massage may irritate the healing tissue and is not the preventive approach for hypertrophic scarring.
