Thread veins on the face and body are common and usually harmless, but many people choose to treat them for cosmetic reasons.
ThermaVein is a targeted treatment that uses controlled heat to collapse superficial thread veins, allowing the body to naturally reabsorb them over time. It can be used on both facial and selected body veins and does not involve injections or laser energy, making it suitable for delicate areas.
Visible thread veins can appear on both the face and body, often becoming more noticeable over time. While they are usually harmless, many patients find them cosmetically bothersome, particularly on the nose, cheeks, chin, legs and ankles.
At L’Atelier Aesthetics, ThermaVein is used as a precise, non-surgical solution to treat small thread veins on the face and body, following a full medical consultation to assess suitability and vein type.
ThermaVein is an advanced medical device designed to treat superficial thread veins using controlled thermocoagulation. A fine probe delivers a brief burst of heat directly into the vein, causing it to collapse and gradually be reabsorbed by the body. Unlike lasers or injectable treatments, ThermaVein does not rely on light or chemicals, making it suitable for delicate areas such as the face as well as selected areas of the body.
ThermaVein is most effective for small, superficial thread veins, including:
The ThermaVein probe is placed directly over the thread vein. A short pulse of high-frequency energy heats the vein wall, causing it to collapse. Blood is naturally redirected through healthier vessels, and the treated vein is gradually absorbed by the body over the following weeks.
Treatment is highly targeted, helping to minimise impact on surrounding skin.
Unlike many laser or IPL treatments, Thermavein does not rely on light absorption. Instead, it uses direct heat energy applied precisely to the vessel.
This offers several advantages:
• Highly targeted treatment of individual thread veins
• Suitable for very fine or superficial capillaries
• Minimal impact on surrounding skin
• Safe for a wide range of skin types
• No need for compression stockings or injections
For patients with small red facial veins, this level of precision can provide excellent cosmetic improvement without the downtime associated with more aggressive vascular treatments.
Thread veins can have different underlying causes, particularly on the body. Your appointment will always begin with a medical consultation to:
Assess vein type and suitability
Exclude underlying venous disease where appropriate
Discuss alternative or complementary treatments if needed
Create a tailored treatment plan
This ensures safe, appropriate and realistic outcomes.

Yes, ThermaVein is commonly used to treat small facial thread veins, particularly on the nose, cheeks and chin. ThermaVein is well suited to delicate facial areas because it is highly targeted and does not rely on lasers or injectable solutions.
ThermaVein can be used on selected small thread veins on the body, including the legs, ankles and knees. During your consultation, we will assess whether ThermaVein is appropriate for your vein type or whether another treatment may be more suitable.
Most patients describe ThermaVein treatment as a brief sharp heat or stinging sensation that lasts only a fraction of a second. Discomfort during ThermaVein treatment is usually mild and well tolerated, and anaesthetic is not normally required.
The number of ThermaVein sessions required depends on the size, number and location of the thread veins being treated. Some veins respond to a single ThermaVein session, while others may require multiple treatments for optimal results.
Results from ThermaVein can be seen immediately for some veins, while others fade gradually over several weeks. The full results of ThermaVein treatment typically develop as the body reabsorbs the treated veins.
Veins treated with ThermaVein do not usually return. However, ThermaVein cannot prevent new thread veins from developing in the future, particularly on the legs, where underlying circulation and lifestyle factors play a role.
Common side effects of ThermaVein include temporary redness, mild swelling and small scabs at the treatment site. Less commonly, ThermaVein may cause temporary pigmentation changes or blistering. Serious complications from ThermaVein are rare when treatment is performed by trained professionals.
ThermaVein is suitable for most skin types because it does not use laser energy or light-based technology. Your suitability for ThermaVein will always be assessed during a consultation to ensure safe and appropriate treatment.
ThermaVein and laser treatments target different types of thread veins. ThermaVein is often preferred for very small, superficial veins, particularly on the face, while laser treatments may be more suitable for larger or deeper vessels. A consultation will determine whether ThermaVein is the best option for you.
The most suitable treatment depends on the size, depth and location of your veins. ThermaVein is ideal for very fine, superficial thread veins and broken capillaries, particularly on the face and delicate areas of the body, as it uses precise heat to seal the vessels without injections. Microsclerotherapy is typically recommended for larger, more visible veins on the legs, where a targeted injection is used to collapse the vein so it can be naturally reabsorbed by the body.
In many cases, a combination of both treatments may be advised. Larger feeder veins can be treated with microsclerotherapy, followed by ThermaVein to refine and remove any remaining finer surface veins. During your consultation at L’Atelier Aesthetics, your practitioner will assess your concerns and recommend the most effective approach for your individual needs. You can read more below on this topic.
When it comes to treating thread veins, one of the most common questions we’re asked is whether ThermaVein or microsclerotherapy is the right option. The answer depends on the type, size and location of the veins, which is why a personalised assessment is always essential. ThermaVein is a highly precise treatment that uses controlled heat to seal very small, superficial vessels. It is particularly effective for fine thread veins, broken capillaries and spider veins on the face and delicate areas of the body. Because the energy is delivered directly to the vessel without injections, it allows for targeted treatment with minimal impact on the surrounding skin.
Microsclerotherapy, on the other hand, is typically used for larger, more visible veins on the legs. This involves injecting a solution into the vein, causing it to collapse and gradually be reabsorbed by the body. It is often the preferred approach when veins sit slightly deeper or are too large to be effectively treated with surface-based technologies alone.
In practice, many patients benefit from a combination of both treatments. Larger feeder veins on the legs may first be treated with microsclerotherapy, followed by ThermaVein to address the finer residual thread veins that remain visible on the surface. This combined approach allows for a more complete and refined result.
At L’Atelier Aesthetics, Dr Duncan Brennand and the clinical team will assess your veins in detail and recommend the most appropriate treatment plan based on what will deliver the safest and most effective outcome.

I had one of the best chemical peels with the lovely Kate! The staff were so friendly and welcoming, and the atmosphere was wonderful. Kate made me feel completely at ease throughout the entire experience.

Following ThermaVein treatment at L’Atelier Aesthetics in Harley Street, most patients experience little to no downtime and can return to their normal activities immediately. Some redness or mild sensitivity in the treated area is entirely normal and typically settles within a few hours. Some thread veins disappear straight away, while others fade gradually over the following weeks as the body naturally reabsorbs the collapsed vessels. A follow-up appointment may be recommended to assess results and treat any remaining veins.
