What should you know about CO2 laser treatment for keloids?

A keloid is raised scar tissue that extends beyond the original wound and may itch, feel tender, or continue enlarging. CO2 energy resurfaces or ablates tissue, so it may be considered for selected scar texture or thickness, often as one part of a broader plan. It does not remove the tendency to form keloids.

The clinician should confirm that the lump is a keloid rather than a hypertrophic scar, inflamed cyst, or another lesion. Your previous scars, family history, skin tone, location, symptoms, and response to earlier injections or surgery affect the decision. Recurrence prevention must be discussed before any procedure.

Choose a clinician experienced with abnormal scars and ask whether CO2 is appropriate for the scar’s thickness and activity. Discuss combinations such as injections, pressure, silicone, or other scar care when relevant; the plan should be tailored rather than based on the laser name alone. Do not cut, scratch, or self-treat the area.

Follow wound-care instructions closely, protect the healing surface from sun, and attend review appointments. A keloid can change gradually, so report renewed firmness, itch, tenderness, or spread beyond the treated area.

Contact the clinician for increasing redness, warmth, drainage, fever, severe pain, or a wound that is opening. Arrange review if the scar becomes rapidly larger, increasingly painful, or starts extending beyond its previous border.

How confident are you that this is a keloid? What is CO2 intended to change? What will reduce regrowth risk? Would injections or silicone be combined with treatment, and how will recurrence be monitored?
