Aftercare for CO2 fractional laser treatment

After CO2 fractional laser, expect redness, warmth, swelling, sensitivity and surface crusting as the treated skin repairs itself. Recovery varies with treatment intensity, the area treated and individual skin response. Use the cleanser, moisturising ointment and other products selected by your clinician, because newly treated skin is easily irritated.

The laser creates controlled microscopic treatment zones while leaving intervening skin that supports healing. Redness and a sunburn-like sensation reflect the early inflammatory response; fine crusts or a rough, bronzed surface can develop as damaged surface cells shed. Redness may persist after the skin closes, and pigment changes are more concerning when they become pronounced, patchy or progressively darker.

Wash with clean hands and lukewarm water according to the clinic's schedule, then pat rather than rub. Apply the recommended bland ointment or moisturiser so healing skin does not dry and crack. Do not pick flakes or crusts. Avoid swimming, saunas, vigorous exercise, fragranced products, exfoliants and active skincare until cleared. Once the surface has healed enough for sunscreen, use broad-spectrum protection and limit direct sun exposure.

Seek prompt clinical advice if pain is intensifying rather than settling, redness spreads beyond the treated area, swelling suddenly worsens, or you develop pus, an unpleasant smell, fever or grouped blisters. Report eye pain or visual change urgently after treatment near the eyes. Trouble breathing or swelling of the lips or tongue requires emergency care.

Confirm how often to cleanse, which barrier product to apply and when makeup, exercise and active skincare can resume. Ask how your skin tone influences the risk of darkening or lightening and what sun-protection plan is appropriate. If you have a history of cold sores, verify whether antiviral medicine was prescribed and what to do if tingling or blisters appear.
