Abstract
The role of vascular lasers in the treatment of rosacea is important. Despite the relative low number of studies using an excellent methodology, one can consider that it is un-discussable. Two lasers are mainly used: pulsed dye lasers and KTP lasers. But the main discussion is the choice of the principle of treatment, related to the pulse duration, photocoagulation or selective photothermolysis. Photothermolysis is more effective, mainly on thintelangiectasias and diffuse erythrosis, but it induces purpura, and certain patients do not agree with those side effects. Nd-Yag lasers must be carefully used, because they can induce facial atrophic scars. They are rarely effective, with long lasting results, on flushes, but they improve the quality of life of patients. Their main limit is the logical lack of efficacy on the inflammatory lesions, even if patients often notice an improvement of the disease. Recurrences are common after several years of follow up.
