Foam or Injection Sclerotherapy


Foam injections or sclerotherapy are ideal for smaller varicose veins or unsightly blue veins on the legs.  It is a simple quick procedure that only has a tiny injection at the beginning that then seals off the veins and takes less than 20 minutes in most cases.

After the treatment patients are advised to wear support stockings or tights for up to a week afterwards but can carry on with normal daily activities.

Complete removal of the veins may take a few sessions a few weeks apart.

Large and Bulging Varicose Veins

For larger varicose veins, laser varicose vein removal may be more appropriate.

Thread Veins

Thread veins (or spider veins) are thin veins on the surface of the skin that rarely cause and problems other than being cosmetically unsightly. These are treated by micro injections that you can hardly feel.

Treatment Information

Foam Sclerotherapy Costs

Foam sclerotherapy costs from £500 at Cosmedics’ London Vein Treatment Centre.

In addition, an initial consultation fee of £150 also applies. This includes:

  • private consultation with our top vascular surgeon
  • ultrasound scan, which is completed at our London clinic requiring no separate appointment or referral

The Foam Sclerotherapy Procedure

Firstly, a local anaesthetic is carefully administered to ensure that the procedure is pain-free and comfortable throughout.

Then, a special solution is mixed with air creating a foam which the surgeon will inject very carefully and precisely into the affected vein. If the vein is very deep, then the surgeon may use the ultrasound scanner in order to check that the injection is being placed in exactly the right area.

The foam will immediately start to react. Any blood within the vein will be pushed out. The vein wall itself will become inflamed and ‘sticky’, eventually closing off the vein.

Following the procedure, the varicose vein will shrink and disappear.

The procedure can be done on the same day as the consultation and takes less than 30 minutes. It is carried out under local anaesthesia, so patients do not feel any pain during treatment.

After treatment, a review appointment will be scheduled to check whether further treatment is necessary, as on occasion it might take up to 3 sessions to achieve complete closure of the veins.

Dressings In Clinic

After the procedure, a pressure bandage or dressing will be applied to the leg(s) to ensure that blood cannot seep back in and the walls are compressed together.

This must be worn for 12-24 hours after the injections during which time showering/bathing must be avoided.

Dressings At Home

After the initial dressing is removed, you will need to wear compression stockings for 3-4 weeks for optimum healing and best results.

What to Expect

Expect to feel a bit sore for a few days where the vein has been treated.

It is important to remain mobile with gentle activity. Don’t be tempted to rest too much – a regular walk is helpful to promote good circulation.

You will need to avoid prolonged standing, kneeling, squatting, bending or strenuous exercise for 4-6 weeks.

Elevate your leg when sitting for any length of time.

Does Foam Sclerotherapy Hurt?

The procedure sounds uncomfortable, but as it is done under local anaesthetic so you won’t feel any pain after the initial ‘pin prick’ of the injection itself.

After the procedure, when the anaesthetic has worn off, you may feel some soreness or discomfort. Paracetamol will relieve this.

How Long Does the Procedure Take?

The foam sclerotherapy injections take around 30 minutes.

How Soon Will I See the Results?

Most patients see a difference straightaway, but it can take about 6 weeks to see the finished result.

Will it Last?

Yes, the procedure has an excellent success rate with permanent results.

How Will They Look?

At first, it is relatively common to see some localised swelling, redness or bruising. This passes in a week or two as the legs heal.

  1. Hello, I am very interested in Sclerotherapy. I read that the cost is 500£, is this per session or is it the price for the “whole package”?.
    Thank you very much

    1. Hello, there a number of options depending on the nature of veins:

      • Foam sclerotherapy is for larger blue veins / smaller simple varicose veins. Prices are from £500 per session and 1-2 sessions normally adequate
