A typical procedure lasts about 30 minutes, though can be longer pending on how many veins are treated. The majority of patients will only need one session, though in certain cases, multiple sessions are necessary. Treatments are done at 3 to 4 week intervals. Vessels usually disappear over a period between 2 weeks to 3 months.

Are there any physical restrictions following therapy?
