When Is Fractional Laser Treatment Recommended for a Hypertrophic Scar?

A hypertrophic scar is raised but remains within the original injury area. Fractional laser treatment places microscopic channels in the scar, which may improve surface texture and help a firm scar become more flexible over time. It is not suitable for every raised scar, and a keloid or actively inflamed lesion may need another approach.

The clinician assesses whether the scar is closed and stable, how thick or tight it feels, its position over a joint, skin tone, previous treatment, and any tendency toward excess pigment or abnormal scarring. The goal may be movement and comfort as well as appearance.

Ask a dermatologist or scar specialist to examine the scar before booking resurfacing. Describe itching, tenderness, tightness, changes in size, and any restriction when moving nearby skin or a joint.

Follow the treatment plan for wound care and sun protection. Keep the area clean as directed, avoid picking, and attend reviews. Depending on the scar, laser may be combined with silicone, pressure, injections, massage, or rehabilitation rather than used alone.

Seek assessment for a scar that is rapidly enlarging, hot, increasingly painful, draining, ulcerated, or associated with fever. After laser, report infection signs, severe swelling, blistering, or a marked change in colour that continues to worsen.

Ask whether the scar is hypertrophic or keloid, which symptom the laser is intended to improve, whether another treatment should be combined with it, and how movement, wound healing, and pigment will be monitored.
