Thread Vein Removal

Do you have thread veins or spider veins on your legs that make you feel self-conscious? Perhaps you have painful thread veins or you feel you can’t reveal your legs because of unsightly veins?

You may be looking for an effective treatment option for these veins, especially one that is not invasive. Sclerotherapy is a popular and effective treatment for varicose veins, spider veins and thread veins. During the treatment, we inject a special solution directly into the vein. This solution causes the vein to scar and collapse, forcing the blood flow to re-route through healthier veins. The collapsed vein then breaks down and is reabsorbed into local tissue until it fades away, leaving your skin looking smooth and healthy and feeling pain-free.


  • How does thread vein removal with sclerotherapy work?

    Sclerotherapy is when a special solution called a sclerosant is injected into a thread vein, spider vein or varicose vein. The solution acts as an irritant that damages the lining of the vein and causes it to collapse. Over time, the vein then breaks down and is absorbed by your body so it disappears. The solution normally used for this procedure is called sodium tetradecyl sulphate (STD) and can be used in different concentrations depending on the size of the veins to be treated.

    Sclerotherapy is non-invasive, less expensive than surgery, requires no hospital stay or downtime, and is highly effective, although you may need several treatments for larger, more stubborn veins.

  • What areas can sclerotherapy be used to treat?

    Sclerotherapy is ideal for unsightly and/or painful thread veins, spider veins and varicose veins on the legs.

  • What should I expect from the treatment?

    With sclerotherapy, we use tiny needles and inject very near the surface of your skin, making this a surprisingly comfortable procedure. Some people feel nothing at all, while others feel a pinprick sensation. Depending on which sclerosant we use, you may feel some discomfort when the solution enters your veins but we will discuss this with you in advance and, again, the sensation varies from person to person.

    During the procedure, we will elevate the affected leg to help drain the blood from the thread veins before we inject them with the sclerosant. This procedure can take between five and 30 minutes, depending on the number and size of the veins to be treated.

    You may experience some redness and swelling at the injection sites but these typically resolve within a few hours or days. Your legs may initially look bruised and the veins may look worse before they get better. It’s common for them to look darker, sometimes with blue, black or brown spots under the skin.

    By day 10 to 14 post-treatment, you should notice that the appearance of these veins has noticeably improved. At weeks four to six, the veins may look like they did before your treatment. This is usual. From this point onwards, the veins will begin to fade and the full effect of your treatment will be apparent at 12 weeks.

  • Is thread vein removal with sclerotherapy safe?

    Sclerotherapy is generally a safe procedure with few complications. After your treatment, you may find that you experience bruising, raised red areas, multiple tiny red blood vessels, or darkened skin at the injection site but these side effects are temporary and usually resolve themselves within a few days to several weeks.

    In rare cases, side effects can occur that need treatment; these include inflammation, air bubbles, an allergic reaction, or a blood clot. If you experience any difficulty breathing, chest pain, dizziness, visual disturbances, headaches, coughing or nausea then you should seek immediate medical care.

  • What do I need to do after my sclerotherapy treatment?

    We will give you clear aftercare instructions when you attend the clinic for sclerotherapy – these will depend on the type and number of veins you’ve had treated and where they are on your legs. You will be given support stockings and/or bandages for each treated leg with information about how long you should wear them. We will also explain how much you should walk and any other recommendations that will support your recovery.

    Sclerotherapy generally doesn’t require any down time. You should be able to walk immediately after your treatment, although you may want to take things easy for a couple of days. We may advise you to avoid strenuous exercise for a few days, and you should avoid sun exposure to your legs for two weeks after the procedure.

  • Is sclerotherapy right for me?

    Sclerotherapy is a highly effective way of improving the appearance of thread veins, spider veins and varicose veins. It’s non-invasive, less expensive than surgery and requires little to no downtime, which makes it very appealing for a growing number of people. Sclerotherapy does treat the symptoms of thread veins rather than the cause, so new veins may appear over time. It isn’t always possible to clear 100% of the visible veins, but you should see a 60-80% improvement. Figures suggest that sclerotherapy works well for 80% of patients.

    We would recommend that you come into the Cotswold Face and Body Clinic for a free one-to-one consultation so that you can ask questions and get a clear understanding of what a sclerotherapy is and what you could expect from this treatment. This consultation gives us a chance to assess your veins and create a fully personalised treatment plan for you.
