What are Ablative Lasers?
Ablative lasers remove the top layers of the skin (epidermis) and heat the layer under the epidermis. This causes collagen (a substance that gives skin structure) regeneration. As the wound caused by the laser heals, smoother and more even skin results. There are three types of ablative lasers used for resurfacing: carbon dioxide (CO2), erbium:YAG (Er:YAG), and the long-pulsed erbium:YAG laser.
