RESUMO
Fractional CO2 procedures are an established, safe and effective armamentarium for managing skin rejuvenation and scarring. Very short-pulse-duration devices offer a very high ablated volume/ablated surface ratio, inducing a controlled thermal damage. With this kind of device, each procedure can be customized on the features of the skin of each patient. The same device can be used to treat severe burn scars. With a very deep fractional procedure on a scar tissue, immediate relaxation of the tension and retraction forces may be obtained, and downstream, improvements are related more to the activation of a molecular cascade. The authors review the state-of-the-art, in the use of fractioned CO2 laser technology for aesthetic and scar remodelling indications.
