Sclerotherapy is a relatively simple, pain-free treatment. Depending on the desired results and unique veins, the treatment can take up to 15-60 minutes. Every patient’s treatment and results vary. Typically, treatments on the legs take longer than a facial treatment. We recommend patients coming back for 3-5 treatment sessions to obtain optimal results. It depends on your unique procedure, but sometimes patients will have to apply a compress to relieve the veins.
