The CO₂ fractional laser treatment time is between 30 - 60 minutes with added time for anaesthetic prior to treatment and cooling treatment following.

The CO₂ fractional laser unit delivers a high intensity beam of laser light that penetrates the skin and selectively targets epidermal and dermal cells while leaving surrounding tissue unharmed. The CO2 laser is ablative, meaning that the skin is resurfaced by the laser.

The CO₂ fractional laser treatment is a safe and effective procedure. However, as with any laser skin resurfacing treatment, there may be some temporary side effects including redness, swelling, and bruising. The redness after treatment can persist for up to two weeks so treatments are best scheduled for times when this can be accommodated.

There is minimal aftercare required. Most people only need to keep the treated area clean and apply a healing cream which is provided with treatment. Sunscreen should be used when going outside to minimise the risk of pigmentation change.
