What should you know about CO2 laser facial rejuvenation?

A CO2 laser delivers infrared energy that is absorbed by water in the skin. The clinician can remove a controlled surface layer, heat deeper tissue, or use fractional pulses that leave untreated skin between treatment columns. The intended effects include smoother texture and softened fine lines; acne scars and uneven tone may also be discussed when the pattern and depth are appropriate.

After treatment, the face may be red, swollen, tender, or crusted while the surface repairs itself. The final appearance develops gradually as healing and tissue remodelling continue. Results and recovery vary with settings, skin tone, facial area, medical history, and aftercare.

Choose a qualified medical provider and ask for an examination rather than selecting settings from a picture. Discuss active acne or eczema, cold sores, keloid scars, recent sun exposure, previous procedures, and medicines that affect healing or sensitivity. Before treatment, follow instructions about stopping selected products, avoiding tanning, and arranging help if your eyes or face swell. Afterward, cleanse gently, use the recommended barrier care, avoid picking, and protect healing skin from sunlight.

See [CO2 Laser](/technology/co2-laser/) for the technology and [Acne Scar Laser Treatment](/treatments/laser-and-energy/acne-scar-laser-treatment/) for one possible clinical use.

Call the treating clinic for worsening pain, spreading redness, pus, fever, delayed healing, or a new rash. Seek urgent help for facial swelling that affects breathing or swallowing, serious eye pain, sudden vision change, or a severe allergic reaction. A flare of cold sores near the treated area should be reported quickly because early treatment may matter.

Which concerns can this treatment address on my face? What depth and pattern are planned? How will my skin tone and cold-sore history affect preparation? What will normal healing look like, and when should I contact you?
