Microsclerotherapy is the technique used to treat spider veins or thread veins of the legs. It is a relatively straightforward procedure which involves injecting a liquid into the veins which destroys them and causes them to disappear over time.

It is suitable for use on thread veins on the legs or body, provided they are beneath the heart. Thread veins on the face are better treated with Electro Surgery, Intense Pulsed Light (IPL) or laser. As gravity has an effect on the blood in the veins and also as the skin is more sensitive to burns, Microsclerotherapy is the most preferable treatment for thread veins below the heart.

As thread veins and spider veins are minute, a tiny needle is used to inject small amounts of sclerosant, which is the liquid that destroys the veins.

The veins are so small that a very powerful magnifying glass with a strong circular light is used in order to get the very best view of the target thread veins or spider veins.

As soon as the sclerosant is inside the vein, the vein needs to be compressed and this is done by taping a swab to the skin.
