What should you know about dermabrasion for hypertrophic scars?

A hypertrophic scar is a raised, firm scar that remains within the original wound boundary. It may feel itchy, tender, tight, or sensitive and can change gradually as it matures. Dermabrasion removes or smooths surface layers; it does not reliably flatten the deeper collagen that makes this scar elevated. Treating an active or thickening scar aggressively may prolong inflammation.

The clinician will consider the scar's age, thickness, colour, symptoms, location, skin type, and how you have healed from earlier injuries. A scar that grows beyond the wound edge may be a different type of scar and needs a different discussion. Avoid home sanding, strong acids, or unregulated devices.

Book an examination with a dermatologist or scar specialist before choosing resurfacing. Management may include silicone-based care, pressure approaches, steroid injection into the scar, fractional laser treatment, or surgery in selected cases. Each option has different goals: reducing height, easing symptoms, improving movement, or blending colour and texture.

Keep the area moisturised as advised, protect it from sun, and avoid picking or repeated friction. Tell the clinician about previous scar treatments, allergies, medicines, pregnancy, and any history of raised scars. Ask how the plan will be adjusted if the scar becomes more inflamed or begins to grow.

Arrange prompt review if a scar becomes rapidly larger, increasingly painful, hot, draining, or open. Seek urgent care for spreading redness with fever, severe swelling, or sudden loss of movement near a joint. New growth after a procedure should be assessed rather than covered with another treatment.

Ask whether the scar is hypertrophic or another scar type, whether it is still maturing, and which outcome matters most for you. Discuss the reason to consider steroid injection, laser, or surgery, the chance of recurrence, expected aftercare, and how symptoms will be monitored.
