Visible thread veins can appear almost anywhere on the body, but the right treatment depends less on the technology itself and more on where the veins are and what type of vessels are being treated. While ThermaVein and microsclerotherapy are both effective thread vein treatments, they work in different ways and are generally recommended for different areas of the body. Understanding those differences can help you choose the most appropriate treatment during your consultation.
Thread veins are extremely common and are different from varicose veins. This article focuses on one question instead: which treatment is most suitable for your veins?
Thread veins are small, visible blood vessels that sit close to the surface of the skin. They often appear as fine red, purple or blue lines and are most commonly seen on the face and legs.
Although they can look similar, thread veins are different from varicose veins. Varicose veins are larger, deeper veins that often bulge beneath the skin and may require a different type of assessment and treatment.
Although both treatments aim to reduce the appearance of thread veins, they close unwanted blood vessels in different ways.
ThermaVein uses carefully controlled thermal energy applied to the surface of the skin. The heat seals the tiny visible vessel, allowing the body to gradually absorb it over time.
Microsclerotherapy works differently. A very fine needle is used to inject a specially selected solution into the vein. This irritates the lining of the vessel, causing it to close before the body naturally reabsorbs it.
Because the treatments work in different ways, they are generally suited to different types of thread veins.
For most facial thread veins, ThermaVein is generally the preferred treatment.
The blood vessels on the face are usually very small and close to the skin’s surface. A surface-based thermal treatment allows these tiny vessels to be treated with precision while avoiding injections into delicate facial skin.
ThermaVein is commonly used for thread veins around the:
Many patients notice an immediate visible response in treated vessels, although the final result develops as the skin heals.
Treatment sessions are typically quick, and downtime is usually minimal. Mild redness may occur immediately afterwards, but this generally settles within a short period.
Session numbers and treatment protocols vary between patients and should always be confirmed during your consultation.
Thread veins on the legs are different from those on the face, both in how they develop and how they’re treated.
Leg veins are often slightly larger, sit deeper beneath the skin and are exposed to higher pressure from standing and walking. In some cases, they may also be linked to underlying venous insufficiency, which is why assessment is so important before treatment begins.
For these reasons, microsclerotherapy is generally the preferred treatment for thread veins on the legs.
By injecting a sclerosant directly into the affected vessel, microsclerotherapy allows the vein to close from within before it is gradually broken down by the body. It is widely used to treat thread veins across the thighs, calves and ankles.
Following treatment, patients are usually advised to wear compression stockings for a period of time to support healing and optimise results.
Like facial treatments, more than one session may be recommended depending on the number and size of the veins being treated.
| Feature | ThermaVein | Microsclerotherapy |
|---|---|---|
| How it works | Uses controlled thermal energy to seal the vein | Uses a sclerosant injected into the vein to close it from within |
| Best suited for | Facial thread veins | Leg thread veins |
| Typical treatment areas | Nose, cheeks, chin and forehead | Thighs, calves and ankles |
| Vessel type | Very fine surface thread veins | Slightly larger thread veins in the legs |
| Sessions | Depends on the number of veins being treated | Depends on the number and size of veins being treated |
| Downtime | Usually minimal | Usually minimal, with compression garments often recommended |
| Aftercare | Gentle skincare and sun protection as advised | Compression stockings may be recommended following treatment* |
| Visible response | Many treated vessels respond immediately, with continued improvement during healing | Veins gradually fade as the body naturally absorbs the treated vessels |
Aftercare recommendations vary between patients and will be discussed during your consultation.
Although each treatment has its own strengths, they are not always mutually exclusive. Some patients may benefit from both ThermaVein and microsclerotherapy if they have thread veins affecting different areas of the body.
Rather than choosing one treatment over the other, your practitioner will recommend the most appropriate approach based on the location, size and characteristics of your thread veins.
Every patient presents with a different pattern of thread veins, which is why treatment selection should always begin with a careful assessment rather than a preference for one device over another.
The most important question isn’t which treatment is better, but which treatment is most appropriate for the individual veins being treated. During consultation, Dr. Duncan Brennand will assess the size, location and characteristics of the vessels before recommending the approach most likely to achieve a safe and effective result.
For most facial thread veins, ThermaVein is generally the preferred option. It uses controlled thermal energy to treat very fine surface vessels with precision, making it well suited to areas such as the nose, cheeks and chin. During your consultation, your practitioner will confirm whether your veins are suitable for this approach.
Microsclerotherapy is typically recommended for thread veins on the legs. Because leg veins are often slightly larger and sit deeper beneath the skin than facial thread veins, an injected treatment is generally more appropriate. Your practitioner will assess the type and location of your veins before recommending treatment.
Most patients describe microsclerotherapy as very well tolerated. You may feel a brief scratch as the needle enters the skin and mild stinging as the solution is injected, but discomfort is usually short-lived. If you’d like to learn more, read our guide to whether microsclerotherapy hurts.
The number of sessions varies from patient to patient. It depends on the number of veins being treated, their size and how your body responds to treatment. During your consultation, your practitioner will recommend a personalised treatment plan based on your individual concerns.
The cost of treatment depends on several factors, including the area being treated, the number of veins present and the type of treatment recommended. You’ll receive a personalised quotation during your consultation once your practitioner has assessed your veins and discussed the most appropriate treatment plan.
Successfully treated thread veins do not usually reopen. However, new thread veins can develop elsewhere over time due to factors such as genetics, ageing, hormonal changes or prolonged standing. Maintaining healthy circulation and attending review appointments when recommended can help manage future concerns.
Yes. Some patients benefit from both treatments if they have thread veins affecting different parts of the body. For example, ThermaVein may be used for facial thread veins, while microsclerotherapy treats veins on the legs. Your practitioner will advise whether a combination approach is appropriate for you.
Downtime is usually minimal following both treatments. After ThermaVein, temporary redness may occur before settling naturally. Following microsclerotherapy, you may be advised to wear compression stockings and avoid certain activities for a short period. Your practitioner will provide personalised aftercare advice based on your treatment.
Thread veins are small blood vessels visible close to the skin’s surface, while varicose veins are larger, deeper veins that may become raised, twisted or uncomfortable. Because they are different conditions, they often require different assessment and treatment approaches. Read our guide to thread veins to learn more.
The most appropriate treatment depends on where your thread veins are located and the type of vessels being treated. In general, ThermaVein is best suited to the fine thread veins commonly seen on the face, while microsclerotherapy is usually recommended for thread veins on the legs. In some cases, patients benefit from both treatments as part of a tailored treatment plan.
A consultation allows your practitioner to assess your veins, discuss your concerns and recommend the approach most likely to achieve a safe, natural-looking result. Rather than focusing on the treatment itself, the aim is to find the solution that’s right for your individual anatomy and goals.
