What should you know about cnc laser co2?

CO2 laser energy is absorbed by water in the skin. Depending on the settings, it can vaporise very thin surface layers or create controlled columns of heat while leaving intervening skin intact. This may improve selected scars, uneven texture, and sun-related surface changes, but it also creates an inflammatory healing process. [CO2 Laser](/technology/co2-laser/) is the technology; [CO2 Laser Resurfacing](/treatments/laser-and-energy/co2-laser-resurfacing/) is one treatment using it. [Acne Scar Laser Treatment](/treatments/laser-and-energy/acne-scar-laser-treatment/) may use laser resurfacing for suitable scars.

During consultation, disclose active acne, cold-sore history, eczema, darker marks after inflammation, medicines, smoking, and previous procedures. Ask whether ablative or fractional settings are planned and how the treated area will be protected. After treatment, follow instructions for cleansing, ointment, dressing, and sun avoidance; do not peel crusts or restart retinoids and acids until cleared. Recovery can include redness, swelling, warmth, peeling, and temporary sensitivity. [Laser Skin Resurfacing](/treatments/laser-and-energy/laser-skin-resurfacing/) covers the broader treatment category.

Contact the treating clinic for worsening pain, spreading redness, pus, fever, delayed healing, new blisters, or a marked dark or pale colour change. Eye pain, vision change, or swelling that interferes with opening the eye needs urgent assessment. Avoid further products or procedures on the area until the clinician advises you.

Which CO2 approach and depth match my concern? What is the plan for preventing infection, cold-sore reactivation, or pigment change? How long should I expect visible healing in this area? When can I resume active skincare, makeup, exercise, and sun exposure?
