Leg thread veins, sometimes called spider veins, are small, visible blood vessels that appear just beneath the surface of the skin. They often develop on the legs and can range in colour from blue or purple, or sometimes red or pink, depending on their size and depth. While they don’t usually cause physical discomfort, many people feel self-conscious about how they look, especially when they appear in more noticeable areas. The good news is that leg thread veins are very common, and there are safe and effective treatments available to help reduce their appearance and restore confidence in your skin.
How are Leg Thread Veins Treated
At VeinCentre, we offer simple, effective treatments to reduce the appearance of leg thread veins and help you feel more confident in your skin. Our experience has shown that microsclerotherapy is the most effective form of thread vein treatment – a walk-in, walk-out treatment that involves using a very fine needle to treat the affected veins with a solution that helps them close and fade over time. This treatment is suitable for smaller leg veins that sit just beneath the skin’s surface and is carried out by our experienced Vascular Consultants.
In some cases, your Consultant might recommend thermocoagulation if appropriate.
The number of sessions you’ll need depends on how many veins are being treated and how your body responds. Your Vascular Consultant will discuss this with you at your consultation, along with pricing and what results to expect. Most people are back to normal activities the same day, with very little downtime and minimal aftercare.
Treatment Type: Microsclerotherapy
Microsclerotherapy is a safe and effective treatment for leg thread veins. It works by inserting a special solution directly into the affected veins, causing the vein walls to stick together and gradually collapse. Over time, your body naturally absorbs these treated veins, leaving your skin clearer.
While some improvement may be visible straight away, it typically takes a few weeks for the full results to develop as the veins fade. Most people require two to four sessions to achieve the best outcome, depending on the number and size of thread veins present. Each session lasts around 30 to 45 minutes and is carried out as a simple outpatient procedure, with no need for anaesthetic or downtime.
Treatment Type: Thermocoagulation
Thermocoagulation is a precise and minimally invasive treatment for thread veins, using controlled bursts of microwave energy to target and close the affected veins. The heat is delivered through a tiny needle that gently touches the skin’s surface, directly over the vein. This causes the delicate vein walls to collapse and disappear, without harming the surrounding tissue.
Treatment involves applying heat at regular 2–3mm intervals along the length of each vein. Most veins fade instantly, with the full results continuing to improve over time. Each session takes around 30 minutes, and most people need from two to four sessions for optimal results.
Your Thread Veins Treatment in 3 Simple Steps
We’ve been treating leg thread veins since 2003, using a carefully developed treatment pathway designed to assess and manage all types of visible leg veins. While thread veins are usually a cosmetic concern, we still take diagnosis seriously to ensure there are no underlying issues, such as varicose veins, contributing to their appearance.
Our team of Vascular Consultants uses advanced scanning and tailored treatments to deliver safe, effective results. With a strong reputation for precision and care, we aim to help you feel confident in your skin again.
The VeinCentre Consultation
Your journey begins with a detailed consultation. During this appointment, your Vascular Consultant will carry out a duplex ultrasound scan to assess your leg veins. This scan is the only way to rule out any underlying venous issues before proceeding with treatment. Typically, patients require 1 to 3 sessions. Your Consultant will recommend the number of sessions required to achieve the desired result. It’s very common to need between two and four appointments.
Initial Treatment
Most leg thread veins are treated using microsclerotherapy. If your veins are slightly larger, your Consultant may recommend foam sclerotherapy instead. In many cases, thread veins are not caused by deeper vein problems, but if an underlying issue is identified, we’ll guide you through our dedicated varicose vein treatment pathway to ensure the best outcome.
Further Treatment
We usually recommend leaving at least four weeks between sessions so your Vascular Consultant can properly assess your progress. While thread vein treatment is highly effective, results can take time to fully develop. We’re here to support you throughout.

Can You Get Leg Thread Veins Treated On the NHS?
While the NHS does offer treatment for some vein conditions, leg thread veins are usually considered a cosmetic concern. This means treatment is not typically available unless your symptoms are causing significant pain or affecting your daily life. As a result, many people explore private options for thread vein removal.
At VeinCentre, we offer safe, consultant-led treatment options such as microsclerotherapy and foam sclerotherapy, delivered in a calm and supportive setting. With no GP referral needed and walk-in, walk-out care, we make the process simple and transparent from day one.
If you’re unsure about your options or want to talk through next steps, we’re here to help. With over 40 clinics across the UK, there’s likely to be a VeinCentre near you.

Are There Any Risks with Thread Vein Treatment?
Leg thread vein treatments like microsclerotherapy and thermocoagulation are considered very safe when carried out by experienced Vascular Consultants. Side effects are usually mild and temporary – you might notice slight bruising, itching, or redness around the treated area, which should settle within a few days. In some cases, skin discolouration or small, firm patches can develop as the body absorbs the treated veins, but these tend to fade over time. Your Consultant will talk you through everything at your consultation, so you know exactly what to expect and feel fully reassured about your care.
Leg Thread Veins Treatment Aftercare
After your appointment, you’ll need to wear a support stocking for seven days. While this means avoiding swimming during that time, it won’t limit your everyday movement, and you’ll be fine to drive the same day. Most people can return to their normal activities straight after treatment, and we encourage you to go for a gentle 20-minute walk each day to support your recovery.
We’ll talk you through any activities to avoid, but generally we recommend steering clear of horse riding and heavy weightlifting for a week. The procedure and recovery are usually described as mildly uncomfortable, rather than painful, and most patients are surprised by how manageable it feels.
Tips for a Smooth Recovery
To ensure the best possible leg thread vein treatment recovery time, follow these aftercare tips:
- Wear your support stocking continuously for 7 days after treatment to support healing and optimise results.
- Take a gentle 20-minute walk each day to encourage healthy circulation.
- Avoid swimming, horse riding and weightlifting for one week to prevent irritation.
- Try to stay active, but avoid standing or sitting for long periods without movement.
- Keep the treated area clean and dry, and follow any care instructions given to you.
- Contact us if you notice anything unexpected or have any concerns, we’re here to help.
