The Ablative Fractional Laser (AFL) is a wounding laser, which delivers micro fractional columns of laser light to the top layers of the skin. This treatment works by creating thousands of microscopic areas, through heat, where the top layer of the skin is ablated (removed). These tiny areas of damage are surrounded by untreated skin, this allows healing of the skin. Traditional ablative laser resurfacing can take on average up to three weeks to heal. Types of ablative treatments include the carbon dioxide (CO2) laser and the erbium laser. AFL is performed under local anaesthesia.
