CO2 Fractional Laser An ablative fractional laser that addresses scars directly

CO2 Fractional Laser is an ablative fractional laser that delivers carbon dioxide laser energy divided into microscopic dots. It creates microscopic thermal channels in the skin, and the normal skin remaining between them aids recovery so that collagen regeneration takes place. It is used to induce regeneration in scarred and pore areas.

It is mainly used for depressed acne scars, uneven skin surface, enlarged pores, and rough texture. Scars call for different approaches depending on their shape (boxcar, rolling, ice pick) and when they formed, so we check at consultation whether a scar is suited to CO2 Fractional Laser beforehand. Scars caused by tethering may need another method alongside, since laser alone is not enough.

It is not suitable for everyone, so the decision is made after consultation. Results vary greatly depending on skin type and baseline condition, and excessive treatment on skin that is already sensitive or slow to recover can instead make it more sensitive. In such cases, we may recommend a plan that builds the skin's foundation with a less invasive approach beforehand.

CO2 Fractional Laser is one of the components that can be included in the Scar Combination Program. The Scar Combination Program combines subcision, TCA cross, Legato II, erbium shouldering, and others according to scar type, and within it CO2 Fractional Laser is considered for refining surface irregularities and scar edges. Whether to use it on its own or in combination is decided based on the condition of your scars.

The pain is moderate, and treatment proceeds after topical numbing cream to manage discomfort. How much you feel depends on the intensity and coverage and varies by individual. If you feel uncomfortable during treatment, please tell us right away.

CO2 Fractional Laser is a treatment with relatively significant downtime. After treatment, redness and warmth appear along with fine scabs, and some redness may remain for a while even after the scabs fall off. The recovery period depends on intensity and coverage, so if you have an important event, let us know at consultation and we will adjust the timing and intensity together.

Multiple sessions are often needed depending on scar depth and skin response. The next session proceeds after the skin has sufficiently recovered, so intervals are typically 4-6 weeks or more, set after checking recovery. The total number of sessions is advised after consultation based on the condition of your scars.

Collagen regeneration continues after the surface recovers, so change appears gradually over several weeks to months. The goal is to reduce scar depth and edges as sessions accumulate. The degree of improvement varies widely by individual depending on scar depth and skin condition.

Redness, swelling, and scabs occur after treatment, and hyperpigmentation may develop if the skin is exposed to UV during recovery. If the intensity is too high for your skin condition, the skin can instead become more sensitive, so intensity is set to match your skin type and baseline condition. Infection or worsening of scars may rarely occur, so please contact us right away if anything feels wrong during recovery.

If there is infection or a wound in the treatment area, you have recently had strong UV exposure or tanned, take photosensitizing medication, or are pregnant, treatment is postponed or adjusted. If you are prone to keloids, or are taking or have recently taken oral acne medication (isotretinoin-type), be sure to tell us at your visit as well. If your skin has become sensitive, we may recommend stabilizing the skin's foundation beforehand.

Wash gently without rubbing, then apply the ointment and moisturizer we recommend generously. Do not pick off scabs; letting them fall off naturally reduces the risk of hyperpigmentation. During recovery, apply sunscreen of SPF30 or higher daily and reapply every 2 hours when outdoors.
