Which intervention minimizes the risk of scar formation?

• A. Sun exposure.
• B. Pressure dressings.
• C. Massage therapy.
• D. Avoid moisturizers.

Answer: (B)

The key idea is that scar formation can be shaped by mechanical forces on healing tissue. Applying constant external pressure to a healing burn scar influences how the scar tissue lays down collagen. This pressure reduces blood flow and edema in the scar, which slows and normalizes collagen production, helping fibers align more evenly and the scar to become thinner and flatter over time. That mechanical loading is the most effective way among common interventions to minimize hypertrophic scarring and improve cosmetic outcome, especially during the remodeling phase.

Sun exposure can worsen pigment changes in a scar, and while massage therapy and moisturizers have their roles in scar management (massage aiding pliability, moisturizers supporting skin health), they do not actively reduce scar thickness or hypertrophy to the same extent as compression therapy.
