✦ Synopsis

Non-ablative fractional photothermolysis (nFP) produces specific thermal injury areas called microthermal treatment zones (MTZ) at specific depths in the skin. The surrounding tissue of the MTZ and the stratum corneum of the epidermis remain intact during treatment, leading to rapid healing of the injured tissue. Macroscopic wounding is not apparent. Mild to moderate erythema and edema are usually apparent for several days post-treatment, therefore there is only minimal downtime for the patient. Several treatment courses are required, as it is known from other non-ablative laser procedures. Recently a novel prototype ablative CO 2 laser device operating in a fractional mode (ablative fractional photothermolysis, aFP) has been developed, presenting a new and promising laser technology in skin resurfacing.
