What should you know about CO2 pixel laser resurfacing?

CO2 pixel laser resurfacing delivers laser energy in a pattern of small treatment zones, leaving untreated skin between them to support healing. It may be considered for texture, fine lines, scars, or changes related to [Sun-Damaged Skin](/conditions/photoaging/), but settings and suitability must be tailored to the individual.

“Pixel” usually refers to a fractional pattern rather than one solid pass over every part of the surface. The device creates microscopic columns or spots of controlled injury, while the untreated areas help the skin repair around them. Redness, heat, swelling, peeling, crusting, pigment alteration, infection, and prolonged irritation are possible, with recovery varying by intensity and skin characteristics.

The technology is a form of [CO2 Laser](/technology/co2-laser/); [Laser Skin Resurfacing](/treatments/laser-and-energy/laser-skin-resurfacing/) describes the wider treatment category.

At consultation, show the clinician your goals and disclose active skin disease, cold sores, medicines, previous procedures, tanning, and any tendency to develop dark marks or raised scars. Use the prescribed cleansing and moisturising routine, protect the area from sunlight, and avoid picking or adding irritating products while the barrier heals.

Ask whether a different approach, including a [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/) or [Thulium Laser](/technology/thulium-laser/), better matches your concern and recovery preference.

Contact the clinic promptly for worsening pain, expanding redness, pus, fever, unusual odour, extensive blistering, or healing that is slowing rather than improving. Seek urgent care for eye pain, visual change, or swelling that affects breathing.

How dense and deep will the pixel pattern be? What recovery signs are expected for my skin tone? How will you prevent and manage pigment changes? When may I resume exercise, makeup, and active skincare?
