Is a procedure used to treat blood vessels or blood vessel malformations (vascular malformations) and also those of the lymphatic system. A solution is injected into the vessels, which makes them shrink. It is used for children and young adults with vascular or lymphatic malformations. In adults, sclerotherapy is often used to treat varicose veins and haemorrhoids. Injecting the unwanted veins with a sclerosing solution causes the target vein to immediately shrink, and then dissolve over a period of weeks as the body naturally absorbs the treated vein. Sclerotherapy is a non-invasive procedure taking only about 10 minutes to perform. The downtime is minimal, in comparison to an invasive varicose vein surgery.


Anyone can suffer with thread (red, spider or broken) veins, and they can appear on any part of the body.

Microsclerotherapy is the technique of injecting thread veins with a special substance known as a sclerosant, usually a solution called sodium tetradecyl sulphate that causes swelling in the veins wall. If the vein is small enough, the swelling will destroy the vein over several weeks, making it much less noticeable or even invisible. It is mostly used for leg and other thread veins on the body but is rarely used on the face, where laser or IPL treatments are often favoured, owing to the small possibility of scarring that can occur with microsclerotherapy.

In practice, most people require between 2 and 6 treatments at 4 to 8 week intervals, depending on the size of the veins, and 75% disappearance of the veins is expected.

To help you distinguish between thread veins and varicose veins the following may act as a guideline:


Usually deeper beneath the skin, being skin coloured or bluish – green and more than 2mm in diameter.

They are more serious than thread veins. They can be painful and are a sign of leg pump failure.

Depending on where the thread veins are situated, different treatment options are available. These range from micro-sclerotherapy which is mostly used for leg and other thread veins on the body (but rarely the face) to microwave treatment and laser or IPL treatments and electro-coagulation or electrolysis. In this section, we are just concentrating on thread vein treatment by micro-sclerotherapy.

Thread veins, Usually very near the surface of the skin, red, blue, or purple in colour, and less than 1 to 2 mm in diameter.

They are not regarded as a serious medical condition but they can occasionally ache.

The procedure

There is usually minimal or no discomfort during micro-sclerotherapy injections due to the size of the needle and the superficial injection technique.

The solutions used may differ in strength slightly depending on the size of the vessel to be injected. Ours professionals  will decide which solution is best for your particular case.

Following injections, a swab may be taped over the treated area, and often a special bandage and compression stocking is applied which may be worn for several days to help assist shrinkage of the thread veins.

·         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.

·         In practice, most patients require between 2 and 6 treatments at 4 to 8 week intervals.

·         It is common for around 75 percent or more of your veins to vanish, but you should be aware that 100 percent disappearance of all veins may not be achievable
