varicose veins in women.jpg


Sclerotherapy treatment is used to safely treat thread/spider veins on the legs.

Thread veins develop as you age - it is thought pregnancy and menopausal hormonal changes provoke their development, which is why women are more affected than men.

Approximately 20% of women in their 20s have thread veins, which rises to around 50% for those in their 40s and by the age of 70 over 70% of women will have thread veins.

Sclerotherapy is an effective and easy way to treat thread veins. As thread veins spread and grow they can become more difficult to treat, so early intervention will save you a great deal of time, trouble and expense.

Sclerotherapy has a great safety record and is practiced by the NHS. NICE (National Institute for Clinical Excellence) found Sclerotherapy to be effective and that, on average, was effective in 84 out of 100 cases.

Common side effects are temporary blisters, crusts scabs, bruising and pigmentation which will disappear during recovery. In rare cases, usually when aftercare instructions have not been followed, large weeping blisters can appear. In extremely rare cases the treatment can lead to blood clots. Our doctors and nurses provide highest standard of care and should you need support they will answer your questions or resolve any concerns.

How does Sclerotherapy work?

Sclerotherapy involves injections, using a tiny fine needle, of  a chemical solution into each individual thread vein to make the vein lining sticky. Compression is then applied, by you wearing a compression stocking, to close the veins and make their walls stick together. The veins seal closed and then fade away.

What are the benefits of Sclerotherapy?

  • The treatment does not leave any scars.

  • The treatment is more effective on leg veins than IPL treatments which are better suited to facial veins. 

  • The treatment is painless.

Who is suitable for treatment?

Healthy skin of all skin colours can be treated with Sclerotherapy. 

 If you are suffering with varicose veins that are causing you discomfort, swelling or ulcers then you should consult your GP. The NHS will not treat thread veins, but it does treat varicose veins causing these complications.

What is involved in a treatment?

You must first have a consultation to ensure Sclerotherapy is an appropriate solution for your veins. As each vein has to be injected the process is time consuming, so 1-4 appointments may be required depending on the number of thread veins to be treated. appointment are typically 30-45 minutes. Your practitioner may apply a topical anaesthetic to make the treatment more comfortable.

After each treatment you must wear a compression stocking continuously for 72 hours, during which time you must not allow it to get wet.  The stocking acts as a bandage as well as keeping the vessels closed. When you first remove your stockings it is normal for the veins to look worse before their appearance improves. You must continue to wear the stocking during the day for the next 7 days to promote recovery.

What is involved in recovery?

Wearing the compression stocking is an essential part of the treatment as it allows time for the vein walls to stick together and become closed. As the stockings are thick they can be hot and uncomfortable during the summer months, so this treatment is best done in autumn and winter when it is cooler and easier to cover up.

For 2 weeks after treatment you must avoid:

  • Flying.

  • Swimming pools, spas, saunas and beaches.

  • High impact exercise.

  • Waxing your legs or other hair removal treatments.

You will be seen by your Aesthetic Practitioner for a complimentary review between 14-28 days.
