# Thread Veins Removal Clapham: Microsclerotherapy and Laser from £180
Reviewed by our specialist vascular surgeon
Thread veins removal Clapham is available at SW11 Medical Clapham for patients who want clearer-looking legs or facial skin with safe, medically led assessment. Based at 45 Lavender Hill, London SW11 5QW, close to Clapham Junction, our clinic offers microsclerotherapy from £180 per session and laser from £220 per session for thread veins / spider veins. Because visible thread veins can sometimes be linked to deeper vein problems, our specialist vascular surgeon can assess whether a Duplex Doppler ultrasound scan is needed before treatment. The aim is to choose the right treatment, set realistic expectations and help you understand aftercare before you begin.
## Thread veins removal Clapham: what are thread veins?
Thread veins, also called spider veins, are small visible blood vessels that sit close to the surface of the skin. They may look red, purple or blue and often appear as fine lines, clusters, webs or branching patterns. They are common on the legs, especially around the thighs, calves, ankles and behind the knees. They can also appear on the face, particularly around the nose and cheeks.
Thread veins are different from varicose veins. Varicose veins are usually larger, raised or bulging veins that can cause aching, heaviness, swelling, throbbing or skin changes. Thread veins are usually smaller and flatter. For many patients they are mainly a cosmetic concern, although some people also notice local tenderness, burning or itching.
At SW11 Medical, treatment is chosen according to the size, depth, colour and location of the veins, as well as whether there are symptoms suggesting an underlying circulation issue. A short assessment before treatment is important, as no treatment can guarantee a specific cosmetic result and not every visible vein is suitable for the same approach.
## Thread veins vs spider veins vs varicose veins
The terms “thread veins” and “spider veins” are often used to describe the same condition. They usually refer to tiny superficial vessels that are visible through the skin. “Spider veins” describes the web-like pattern that some clusters form. “Thread veins” is a broader everyday term for fine, visible vessels.
Varicose veins are different. They develop when valves inside the veins do not work properly, allowing blood to flow backwards and pool. This is known as venous reflux. Varicose veins are commonly larger, may bulge under the skin, and can be associated with discomfort or swelling. If you have obvious varicose veins as well as thread veins, treating the surface vessels alone may not give the best long-term cosmetic improvement.
This is why our clinic also provides assessment for patients who may need more than cosmetic treatment. If you have bulging veins, leg heaviness, ankle swelling, skin staining, eczema-like skin changes or previous vein problems, you may be advised to consider a [Duplex Doppler ultrasound scan in SW11](https://sw11clinic-clapham.co.uk/duplex-doppler-scan-sw11/) before cosmetic vein treatment.
## What causes thread veins on the legs and face?
Thread veins can appear for several reasons, and often there is more than one factor. On the legs, they may be linked to family tendency, pregnancy, hormonal changes, prolonged standing, previous injury, ageing, or pressure in the superficial veins. Some patients develop thread veins without any clear cause.
On the face, thread veins are often related to delicate or reactive skin, sun exposure, rosacea-prone skin, ageing, temperature changes or previous inflammation. Facial thread veins tend to be smaller and more superficial than leg veins, which is one reason laser treatment may be preferred for certain facial vessels.
Lifestyle changes can support skin and vein health, but creams and home devices rarely remove established thread veins reliably. A clinical assessment helps identify whether microsclerotherapy, laser, or another plan is more suitable.
## Why duplex assessment may be needed first
Before treating leg thread veins, it is important to consider whether deeper vein reflux is present. This is especially relevant if you have symptoms, larger visible veins, previous vein treatment, or thread veins concentrated around the ankles. If underlying reflux is not identified, surface treatment may be less effective, and new veins may appear sooner.
A Duplex Doppler ultrasound scan uses sound waves to look at blood flow in the leg veins. It is non-invasive and helps the clinician see whether the valves are working properly. At SW11 Medical, a Duplex Doppler ultrasound scan is £340, same-day written results. If you need a full assessment, a vascular consultation with specialist vascular surgeon is £180 (state clearly).
Not every patient needs an ultrasound before thread vein treatment. However, if there are symptoms or signs of varicose veins, it is safer to check first. Patients with confirmed varicose veins may be advised to read about [varicose veins treatment in Clapham](https://sw11clinic-clapham.co.uk/varicose-veins-treatment-clapham/), including Varicose veins EVLA (endovenous laser ablation): from £1,200 per leg.
## Microsclerotherapy from £180 per session
Microsclerotherapy is commonly used for thread veins and spider veins on the legs. During treatment, a very fine needle is used to place a sclerosant solution into the small visible veins. This irritates the lining of the vessel, causing it to close down gradually. Over time, the treated vein fades as the body naturally absorbs it.
The procedure is performed in clinic and usually does not require anaesthetic. Patients often describe a brief stinging or mild discomfort at the injection points. Several small veins can usually be treated in one session, depending on the area and how the veins respond.
Thread veins / spider veins: microsclerotherapy from £180 per session, laser from £220 per session. The exact number of sessions is quoted after assessment because this depends on how widespread the veins are, whether they are fed by larger veins, and how your skin responds. Microsclerotherapy is usually best suited to leg thread veins rather than facial veins.
After treatment, the veins often look temporarily more noticeable before they fade. Mild redness, bruising, itching or tenderness can occur. Your clinician will explain what is expected and what should prompt you to contact the clinic.
## Laser from £220 per session
Laser treatment can be helpful for fine superficial thread veins, particularly on the face and for selected smaller vessels on the legs. The laser targets the colour within the blood vessel, heating it so that the vessel closes and gradually becomes less visible. It does not involve injections, which may make it suitable for patients with very small vessels that are difficult to inject.
Laser treatment can feel like a quick hot flick on the skin. Cooling or other comfort measures may be used depending on the treatment area and device. The area may look red or slightly swollen afterwards, usually settling with simple aftercare.
Laser is not always the best option for larger leg thread veins or blue-green vessels that sit deeper under the skin. In these cases, microsclerotherapy may be more appropriate. The specialist vascular surgeon will advise which option is likely to be safest and most effective for your pattern of veins.
## Microsclerotherapy vs laser: which is better?
There is no single best treatment for every patient. The right option depends on the location, size and depth of the thread veins, your skin type, your symptoms, and whether underlying reflux is present. Some patients may benefit from a combination plan, with larger leg thread veins treated by microsclerotherapy and finer residual vessels treated later by laser.
| Feature | Microsclerotherapy | Laser |
|—|—|—|
| Typical use | Commonly used for leg thread veins and spider veins | Often used for facial thread veins and selected fine vessels |
| How it works | Fine injections close the small visible veins | Light energy heats and closes targeted superficial vessels |
| Starting price | Thread veins / spider veins: microsclerotherapy from £180 per session | Thread veins / spider veins: laser from £220 per session |
| Best suited to | Blue or purple leg thread veins that can be safely injected | Red, fine, superficial vessels, especially on the face |
| Discomfort | Brief stinging or mild injection discomfort | Hot flicking sensation on the skin |
| Downtime | Usually minimal, but bruising and tenderness can occur | Usually minimal, with temporary redness or swelling |
| Sessions | Often more than one session, depending on extent | Often more than one session, depending on extent |
| Important limitation | Underlying reflux should be excluded where indicated | Not ideal for every vein depth or colour |
## How many sessions will I need?
Many patients need a course of treatment rather than a single appointment. The number of sessions depends on the amount of thread veins, how dense the clusters are, the size of the area, your skin response, and whether there is deeper venous reflux. Small facial areas may need fewer sessions than widespread leg veins, but this varies.
It is normal for treated veins to fade gradually rather than disappear immediately. Some veins respond well, while others may need repeat treatment. New thread veins can also develop over time, especially if you have a tendency to them. Your clinician will discuss a realistic plan after assessment and will avoid promising a perfect or permanent result.
## Aftercare after thread vein treatment
Aftercare is an important part of achieving the best possible result. You will be given personalised instructions depending on whether you have microsclerotherapy or laser. In general, you may be advised to walk after leg treatment, avoid strenuous exercise for a short period, and avoid hot baths, saunas or intense heat while the skin settles. Sun protection is particularly important after facial laser treatment and for any treated area exposed to sunlight.
After microsclerotherapy, compression hosiery may be recommended depending on the treated area and clinical findings. You may notice bruising, small marks, temporary pigmentation or local tenderness. After laser, redness, warmth or mild swelling can occur. These effects are usually temporary, but you should contact the clinic if you have increasing pain, spreading redness, blistering, ulceration, sudden swelling or any symptom that worries you.
## What results should you realistically expect?
The aim of thread vein treatment is improvement, not absolute perfection. Treated vessels commonly fade over weeks, and the skin can look clearer and less marked. However, results vary. Some veins may only partially respond, some areas may need repeat sessions, and new thread veins may appear later.
For leg thread veins, results are usually best when any underlying varicose vein reflux has been considered first. If the source of pressure is a larger faulty vein, treating only the surface vessels may lead to disappointing or short-lived improvement. For facial thread veins, reducing triggers such as sun exposure or skin inflammation may help maintain results, although it cannot prevent every new vessel.
NHS access to cosmetic thread vein treatment is limited and subject to eligibility criteria. For many patients, NHS treatment is not available unless there are significant medical symptoms or complications. Waiting times for vein services can be long, often many months and sometimes over a year in London. Private treatment allows assessment and a personalised plan without relying on cosmetic eligibility rules.

## FAQs
### Is thread veins removal painful?
Most patients tolerate thread vein treatment well. Microsclerotherapy can cause brief stinging or mild discomfort during the injections. Laser can feel like a hot flick on the skin. The treated area may be tender, red or bruised afterwards, but this is usually manageable with routine aftercare.
### Do I need a Duplex Doppler ultrasound before treatment?
Not always. If you only have small cosmetic thread veins and no symptoms, you may not need a scan. However, if you have bulging veins, aching, heaviness, ankle swelling, skin changes or previous vein problems, a Duplex Doppler ultrasound scan may be recommended to check for underlying reflux before cosmetic treatment.
### How much does thread veins removal cost at SW11 Medical?
Thread veins / spider veins: microsclerotherapy from £180 per session, laser from £220 per session. If required, a vascular consultation with specialist vascular surgeon is £180 (state clearly). A Duplex Doppler ultrasound scan is £340, same-day written results. Your full plan is confirmed after assessment.
### Will my thread veins disappear completely?
Treatment aims to reduce the visibility of thread veins and improve the appearance of the skin. Some vessels fade very well, while others may need repeat treatment or may not disappear completely. New thread veins can also develop over time, so results cannot be guaranteed.
### Which is better for leg thread veins, microsclerotherapy or laser?
Microsclerotherapy is commonly preferred for many leg thread veins because injections can treat small blue or purple vessels effectively. Laser may be useful for finer superficial vessels or residual redness. The best choice depends on the vein size, depth, colour and whether underlying reflux is present.
### Can I return to normal activities after treatment?
Most patients return to normal daily activities soon after treatment. You may be advised to walk after leg treatment, avoid strenuous exercise for a short period, avoid heat exposure, and follow any compression or skincare guidance. Your clinician will provide aftercare instructions tailored to your treatment.
