Fractional CO2 laser for keloids: what to know

A keloid is scar tissue that extends beyond the original injury and may continue enlarging. It can itch, feel tender, or become firm. Fractional CO2 laser makes microscopic treatment channels that can improve surface texture and may help deliver another medicine into scar tissue when a specialist recommends that combination.

Laser alone may not control the growth tendency. The plan depends on the keloid’s size, site, activity, skin tone, previous treatment response, and whether it is still expanding. Treatment of an active infection or unexplained changing lump must come first.

Arrange an assessment with a clinician experienced in abnormal scars. Bring details of how the scar began and what has already been tried, including injections, pressure, silicone, surgery, or other laser treatment. Ask whether laser is an add-on rather than the main treatment.

After a session, follow wound-care instructions closely. Do not scratch or remove crusts. Avoid unapproved creams, friction, heat, and sun exposure while the surface heals. Attend every planned review because the scar may need ongoing monitoring and maintenance treatment.

Report spreading redness, pus, worsening pain, marked warmth, or delayed healing to the clinic. Seek urgent care for breathing difficulty, swelling of the lips or face, or fever with rapidly worsening symptoms. A keloid that suddenly changes, bleeds, or becomes ulcerated also needs prompt examination.

Ask whether the growth is definitely a keloid, what will be used alongside laser, how recurrence will be monitored, and how your skin tone and past healing affect the plan.
