Sclerotherapy is a medically- proven injection technique which has been used for over 30 years. Using micro-needles a small amount of a salt solution is injected into the vein to dissolve it over a period of time. A course of treatments is usually required.

Sclerotherapy is a safe and well established treatment for thread veins on the legs. Although there are a number of alternative treatments, it remains the most reliably successful of them all.
A solution is injected with a very tiny needle, very superficially into the veins, causing the lining of the vein to swell and become sticky. Compression is then applied to help close the veins. Over a period of time the vein will heal closed and fade away
Although completely safe, it is not entirely without risk. The two most common side effects are something called haemosiderin deposition and telangiectatic matting. Statistically they occur in about 15% of people treated.
Haemosiderin deposition occurs when the vein is not entirely closed, blood is trapped and clots. In some people iron pigments leak from the clot and stain the skin over the vessel brown. These brown marks are usually not permanent but may take 6-18 months to fade. They darken when exposed to the sun and will take longer to fade if tanned.
Matting occurs if the fragile vessel is injured during the injection, leaving a mat of tiny veins that look like a blush or a red bruise. Matting usually disappears completely after 6-12 months, but if it persists, it can be treated with sclerotherapy if the needle can access the fine vessels and flush the solution gently through.
Other risks are extremely rare but these include:
Allergic reaction – any drug carries risk of allergic reaction. It is quite common for patients to experience some itching and some redness at the treatment site. This is no cause for concern and will pass within a few hours. Serious allergic reactions are extremely rare but can occur.
Cosmedical Ltd. (Lynn Warren) have a legal obligation to regularly update on basic life skills and equipment is carried to deal with such events should they occur.
If the solution irritates the tissue surrounding the vein, in rare instances blistering can occur. If left alone these can potentially lead to further blistering and leave a small scar.
There is a risk (rare) that a damaged vein may be tender and painful as it heals, this is more likely to occur behind the knee and will settle down within a couple of weeks.
