Immediately following the treatment, the areas treated will have a red  flush/swelling which usually resolves within 24 hours depending on the intensity  of the treatment and your skin type. Most vessels will disappear during the  treatment but will often reappear when you get home. – This is normal as it takes  time for the body to reabsorb these blood vessels. Some larger vessels may be  reduced in size. Areas treated for abnormal vessels may also form a linear scaly  surface crust. These scabs will fall off by themselves a few days after treatment.  Pigmented spots will turn darker during treatment and will remain visible until the  lesion crusts and falls off naturally 5 to 15 days after the treatment. Downtime is minimal.
