Sclerotherapy Treatment in London – Advanced Leg Thread Vein and Spider Vein Removal
Sclerotherapy Treatment in London
Visible red, blue or purple veins on the legs can affect your confidence, particularly when wearing dresses, shorts or swimwear. These small blood vessels are usually harmless, but they rarely disappear without treatment and may become more noticeable over time.
At Belle Clinic, we offer advanced sclerotherapy treatment in London for suitable leg thread veins and spider veins. Sclerotherapy is a minimally invasive procedure involving the careful injection of a specialised solution directly into selected blood vessels. This encourages the vessels to close and gradually fade.
Located in Golders Green, North West London, Belle Clinic provides personalised vein assessments and professional treatment plans based on the size, colour, position and pattern of your visible veins.
What Is Sclerotherapy?
Sclerotherapy is a non-surgical treatment used to reduce the appearance of certain unwanted veins, particularly thread veins and spider veins on the legs.
A specialised sclerosing solution is injected directly into the affected blood vessel using a very fine needle. The solution irritates the inner lining of the vein, causing its walls to stick together and close.
Blood is naturally redirected through healthier surrounding veins. Over the following weeks and months, the treated vessel is gradually broken down and absorbed by the body, allowing it to fade from view.
Sclerotherapy does not remove blood from the body and should not affect healthy circulation. The treatment targets selected superficial vessels while normal blood flow continues through functioning veins.
What Can Sclerotherapy Treat?
Sclerotherapy may be suitable for:
- Leg thread veins
- Spider veins on the thighs and calves
- Red, blue and purple superficial veins
- Small reticular veins
- Veins around the knees and ankles
- Networks of visible leg veins
- Vessels that may be unsuitable for vascular laser treatment
Sclerotherapy is mainly used for veins on the legs. Facial thread veins are normally better suited to treatments such as Veinwave or vascular laser.
Large, twisted, raised or painful varicose veins may require medical investigation, ultrasound assessment or referral to a vascular specialist.

Benefits of Sclerotherapy
Non-surgical procedure
Sclerotherapy does not require surgical incisions or a general anaesthetic. The solution is administered through small injections directly into the selected vessels.
Minimal downtime
Most patients can return to normal light activities after treatment. Gentle walking is usually encouraged to support healthy circulation.
Multiple veins can be treated
Several thread veins may be treated during one appointment, depending on their size, position and the maximum safe amount of solution that can be administered.
Suitable for different vein patterns
Sclerotherapy can treat certain blue, purple and reticular veins that may not respond as effectively to laser treatment.
Progressive improvement
The treated vessels gradually fade as the body absorbs them. Improvement continues over several weeks or months.
Personalised treatment
The procedure can be adjusted according to the size, location and pattern of the veins.
Can be combined with other treatments
Some patients may benefit from combining sclerotherapy with vascular laser or Veinwave treatment for different types of vessels.
What Is the Difference Between Microsclerotherapy and Foam Sclerotherapy?
Microsclerotherapy uses a very fine needle to inject a liquid solution into small superficial vessels. It is commonly used for cosmetic leg thread veins, spider veins and small reticular veins.
Foam sclerotherapy involves converting the solution into a foam before injecting it into a larger vein. It is generally used for larger varicose veins and may require ultrasound guidance and treatment by a vascular specialist.
Belle Clinic’s cosmetic sclerotherapy treatment is intended for suitable superficial leg thread veins and spider veins. Your suitability must be assessed before treatment.
What Causes Thread Veins on the Legs?
Thread veins can develop for many reasons, including:
- Genetics and family history
- Pregnancy
- Hormonal changes
- Ageing
- Prolonged standing or sitting
- Previous leg injuries
- Increased pressure inside the leg veins
- Being overweight
- Reduced physical activity
- Sun exposure
- Previous vascular conditions
Some people develop thread veins without an obvious cause. Exercise and healthy lifestyle choices may support circulation, but they will not normally remove vessels that are already visible.
What Happens During Sclerotherapy?
Your appointment begins with an assessment of the visible vessels and your relevant medical history. The practitioner will examine the colour, size, position and pattern of your veins.
During the procedure:
- The treatment area is cleansed.
- The appropriate vessels are identified.
- A very fine needle is placed inside the selected vein.
- A small amount of sclerosing solution is carefully injected.
- Several injections may be required across the area.
- Compression may be applied following treatment.
You may experience brief stinging, burning or mild cramping during an injection. Most patients tolerate microsclerotherapy well, and the treatment does not usually require a general anaesthetic or surgery.
Sclerotherapy London: Your Step-by-Step Treatment Journey
Initial Consultation
Your journey begins with an assessment of your visible veins, medical history and treatment goals to confirm your suitability for sclerotherapy.
Personalised Treatment Plan
We create a tailored treatment plan based on the type, size, number and location of the spider veins or thread veins you wish to treat.
Sclerotherapy Treatment
A specialist solution is carefully injected into the targeted veins, causing them to close and gradually fade as the body naturally processes them.
Gradual, Visible Results
Treated veins gradually become less noticeable over the following weeks. More than one session may be recommended, depending on the number and size of the veins.
Sclerotherapy Pros and Cons: Benefits, Risks and Side Effects
Before proceeding, it is important to understand the limitations:
- Results are gradual rather than immediate.
- More than one session may be necessary.
- Complete vein clearance cannot be guaranteed.
- Bruising and temporary pigmentation may occur.
- Treated veins can initially appear darker.
- New thread veins may develop in the future.
- Treatment cannot prevent the natural formation of other veins.
- Compression stockings may be required.
- Large varicose veins may need specialist medical treatment.
- Very fine red vessels may respond better to vascular laser.
- Facial thread veins may be more suitable for Veinwave.
How Many Sclerotherapy Sessions Do You Need?
The number of sessions varies between patients. Some vessels respond after one appointment, while extensive vein networks may need several treatments.
The number of sessions depends on:
- The number of visible vessels
- The size and depth of the veins
- The age of the veins
- The treatment area
- Your circulation
- Your individual healing response
- Previous vein treatment
- The presence of underlying feeder veins
- How closely you follow the aftercare instructions
At Belle Clinic, sclerotherapy sessions are normally spaced approximately six weeks apart to allow the treated vessels sufficient time to respond.
Before Sclerotherapy Treatment
Please follow all personalised instructions provided during your consultation.
General preparation includes:
- Provide your complete medical history.
- Tell your practitioner about all medicines and supplements you take.
- Disclose any history of blood clots or deep vein thrombosis.
- Report previous vein surgery or sclerotherapy.
- Tell the clinic if you have circulation problems.
- Disclose all known allergies.
- Inform the clinic if you are pregnant, breastfeeding or trying to become pregnant.
- Do not apply fake tan, moisturiser, oil or body cream on the day.
- Arrive with clean skin.
- Wear loose, comfortable clothing.
- Bring compression stockings if requested.
- Avoid shaving or waxing immediately before treatment if it irritates your skin.
- Plan the procedure well before holidays, weddings or important events.
Do not stop prescribed medication unless your doctor or prescriber has specifically advised you to do so.
Sclerotherapy Aftercare
Following the correct aftercare instructions is important for healing and achieving the best possible outcome.
Walk after treatment
Gentle walking is normally encouraged following treatment. Movement supports circulation and prevents prolonged inactivity.
Wear compression stockings
You may be advised to wear compression stockings for a specific period. Compression helps support the treated vessels and can reduce swelling and discomfort.
Avoid strenuous exercise
Avoid heavy lifting, running, high-impact exercise and intense gym sessions for the period advised by your practitioner. Light daily activities are usually permitted.
Avoid excessive heat
Avoid hot baths, saunas, steam rooms, hot tubs and heated treatments until advised that it is safe.
Protect your skin from sunlight
Keep the treated area away from direct sunlight. Once the skin is fully intact, use appropriate sun protection to reduce the risk of pigmentation.
Do not massage the area
The veins may temporarily feel firm, lumpy or tender. Do not massage or press the area unless your practitioner has specifically advised you to do so.
Avoid scratching or picking
Small injection marks, redness or tiny scabs may appear. Allow them to heal naturally.
Attend your review
Attend any recommended follow-up appointment so that your treatment response can be assessed.
What to Expect After Sclerotherapy Treatment: Recovery and Results
Temporary reactions may include:
- Redness
- Mild swelling
- Bruising
- Tenderness
- Itching
- Small raised areas
- Firmness along the treated vessel
- Darkening of the treated veins
- Brown pigmentation
- Temporary lumpiness
The veins may initially appear darker or more noticeable. This does not necessarily mean the treatment has been unsuccessful.
Smaller spider veins may begin fading over several weeks, while larger vessels can take several months to improve. Every patient heals differently, and results cannot be guaranteed.
Sclerotherapy Side Effects: When to Seek Medical Help
Who May Not Be Suitable for Sclerotherapy Treatment?
Sclerotherapy may not be appropriate for people who:
- Are pregnant or breastfeeding
- Have an active infection
- Have a current or recent blood clot
- Have certain blood-clotting disorders
- Have severe peripheral vascular disease
- Have poorly controlled medical conditions
- Are unable to walk after treatment
- Have a known allergy to the sclerosant
- Have symptoms requiring vascular investigation
- Have large or complex varicose veins
Suitability is always determined individually.
When Is a Vascular Assessment Required?
Cosmetic microsclerotherapy is designed for suitable superficial vessels. Specialist medical assessment may be required if you have:
- Large or raised varicose veins
- Painful or throbbing veins
- Persistent leg swelling
- Leg heaviness or aching
- Skin discolouration around the ankles
- Venous eczema
- Previous leg ulcers
- Bleeding veins
- A history of deep vein thrombosis
- One leg that is significantly more swollen than the other
These symptoms may indicate an underlying venous condition that should be investigated before cosmetic treatment.
Sclerotherapy Versus Laser Vein Removal
Sclerotherapy and vascular laser treatment can both reduce visible vessels, but they work differently.
Sclerotherapy uses an injectable solution to close the vein. It is commonly selected for blue or purple leg veins and vessels that are too large or deep to respond effectively to laser.
Vascular laser treatment uses controlled light energy to target the blood vessel. It may be more suitable for very fine red vessels, selected superficial veins or patients who cannot undergo injections.
At Belle Clinic, we offer different vein removal options. This allows us to recommend treatment based on the type of vessel rather than using one technique for every client.
