New-Generation CO2 Fractional Laser: What to Know

Fractional CO2 technology delivers laser energy in a pattern of tiny columns rather than treating the entire surface at once. The heat removes or remodels selected portions of skin and stimulates a healing response around them. It may be used for acne scars, uneven texture, fine lines, and some pigment or scar concerns. The settings depend on the area, skin tone, scar depth, and treatment goal. Redness, swelling, warmth, peeling, and temporary colour change can occur during recovery. Darker skin may have a greater risk of post-treatment darkening, so careful selection and aftercare matter.

Have a qualified clinician review your skin, medical history, medicines, tendency to form raised scars, and any history of cold sores before treatment. Follow instructions about sun avoidance and skincare, and do not apply irritating products to recovering skin unless told to do so. Afterward, keep the area clean, moisturised as advised, and protected from light. Do not pick peeling skin. Depending on the goal, your clinician may compare [Fractional Laser Treatment](/treatments/laser-and-energy/fractional-laser-treatment/) with other approaches, including [Acne Scar Laser Treatment](/treatments/laser-and-energy/acne-scar-laser-treatment/).

Contact the treating clinic if pain, swelling, redness, discharge, blistering, or crusting is worsening rather than settling. Prompt assessment is needed for fever, spreading redness, severe pain, or eye symptoms after treatment near the eyes. Tell the clinician if new dark or pale patches persist, because colour change may need specific care. Do not restart active skincare until the treatment team confirms the surface has recovered.

What setting and treatment depth fit my skin and goal? How should I prepare? What recovery changes are expected? How will you reduce the chance of unwanted pigment change?
