What should you know about CO2 laser resurfacing?

The laser is absorbed by water in the skin. A clinician can choose settings that remove a thin surface layer or deliver fractional columns of heat, leaving untreated skin between them. This stimulates repair and can soften uneven texture, some scars, fine lines, or changes related to sun-damaged skin. The treatment is not identical for every person: depth, density, area, skin tone, and previous inflammation shape both the expected result and the recovery. A thulium laser or chemical peel may be considered in different circumstances.

Before treatment, disclose tanning, cold sores, eczema, acne, infection, medicines, and any history of unusual scarring or pigment change. Follow instructions for cleansing and prescribed medicines. During healing, keep the area clean and moisturised as directed, leave flakes or crusts alone, and avoid unapproved acids, retinoids, heat, and strong sunlight. The surface may feel tight, red, swollen, or sensitive while it repairs. Use the treating clinician's advice before applying makeup or returning to active skincare.

Ask for prompt review if pain, redness, swelling, warmth, or discharge is increasing, or if you develop fever, blisters, or a spreading rash. Vision changes, eye pain, or swelling that interferes with breathing or seeing requires urgent assessment.

Ask which resurfacing depth is planned, why it fits your concern and skin tone, how long the visible healing phase may last, and which signs mean the clinic should examine you.
