The treatment is recommended for people suffering from blood vessel disorders, ranging from small telangiectasia called spider veins or broken capillaries to larger maroon spots. It eliminates changes that have been present since birth and that have arisen with age under the influence of the environment, e.g. exposure to the sun. During the procedure, the vessels are damaged and removed by the body's self-defense mechanism. The number of treatments is determined individually, on average 1-4. UV protection is needed at least 4 weeks after the last treatment.
