The number of Vbeam treatments needed varies depending on the severity and type of the condition being treated and individual response to therapy. For the treatment of veins or cherry angiomas, patients may see final results within 1-2 weeks after one treatment. However, most people typically require two to five sessions, spaced two to four weeks apart, for optimal results in treating other conditions such as rosacea, port wine stains, broken capillaries and other vascular conditions. Some patients may respond after one or two sessions, while others may require more.
