CO2 laser healing: what to expect

The treated area may feel tight, tender, hot, or sunburned at first. Redness and swelling can be followed by weeping or crusting, then dryness and flaking as the surface repairs. The depth and pattern of treatment affect how long each stage lasts. Newer skin can be especially sensitive to sunlight and products that normally feel comfortable.

Colour changes can occur during recovery. Temporary darkening is more common after inflammation, while lighter areas may take longer to blend with surrounding skin. Healing can be uneven across cheeks, the forehead, around the mouth, or scarred areas. A clinician assesses whether a change fits the expected course.

Follow the aftercare plan supplied by the treating clinician. Clean the area gently as directed, keep it appropriately moist if advised, and do not pick peeling skin or crusts. Avoid fragranced products, exfoliating acids, retinoids, scrubs, heat exposure, swimming, and strenuous activity until you are told they are suitable.

Protect the recovering skin from sunlight with shade, clothing, and the recommended sunscreen once the surface allows it. Use only prescribed medicines or dressings as instructed. A follow-up visit can check re-epithelialisation, infection, scarring, and colour changes.

Contact the treating clinic promptly for worsening pain, spreading redness, increasing warmth, pus, an unpleasant smell, fever, or blisters that are not part of the agreed aftercare plan. Seek urgent help for facial swelling that affects breathing or swallowing, eye pain, or sudden vision changes.

Ask which cleansing method, ointment, dressing, and pain relief are appropriate for your treatment depth. Clarify when you may restart active skincare, exercise, swimming, makeup, and hair removal, and what degree of redness or colour change should trigger a review.
