When is CO2 laser resurfacing recommended for acne scars?

A fractional or fully ablative CO2 treatment removes or heats controlled layers of skin, prompting new collagen formation during healing. It is generally discussed for atrophic, or indented, scars such as boxcar or rolling scars. Raised scars, ongoing inflamed acne, infection, poor wound healing, or a tendency to form thick scars can change the plan. Skin tone, scar depth, previous treatments, and the location of the scars all affect whether resurfacing is appropriate.

The aim is to soften uneven texture, not to erase every mark. A consultation should separate true scars from lingering colour changes, because laser resurfacing addresses texture more directly than pigment.

Arrange an assessment with a dermatologist or suitably trained laser clinician. Ask whether active acne should be treated first, which scars are likely to respond, and whether a gentler approach or another procedure fits better. Share your medicines, history of cold sores, previous scar reactions, and any tendency toward darkening after skin injury. Follow the preparation plan, protect the area from sun, and plan for redness, swelling, peeling, and a period when the skin barrier needs careful support. Use only the cleanser, ointment, and sunscreen recommended for the healing phase.

Contact the treating clinic promptly if pain, warmth, swelling, or redness is worsening rather than settling, or if blisters, pus, fever, or spreading crusting develop. Seek urgent medical help for trouble breathing, facial swelling affecting the eyes or mouth, or a severe allergic reaction. A new, rapidly changing, bleeding, or persistently sore spot should be examined rather than assumed to be an acne scar.

Which scar types do I have, and what change is realistic? Should my acne or pigmentation be treated first? What settings and number of sessions do you expect? How should I prepare my skin and manage healing? What symptoms would mean I should contact you?
