During microsclerotherapy, a very fine needle injects a solution called a "sclerosant" into superficial veins. This solution irritates the vein lining, causing the walls to stick together. Blood flow stops through these veins, and over a few weeks, the collapsed veins are absorbed into nearby tissue while blood is rerouted through healthier veins. This process gradually closes and fades thread veins.
The treatment typically involves minimal discomfort due to the small needle size and superficial injection technique. It lasts about 30-45 minutes, depending on the number of veins treated and their response.
Following injections, the vein needs to be compressed, and this is done by taping a swab over the treated area, and a special bandage and compression stocking may be applied which may be worn for several days to help assist shrinkage of the thread veins.
If the vein is small enough, the swelling will destroy the vein over several weeks, making it much less noticeable or even invisible.
Repeat procedures
A single blood vessel may have to be injected more than once, depending on its size. Repeat injection sessions can be scheduled one week later, but it is better to wait one month between treatments.
