Microsclerotherapy for Leg Thread Veins
Effective Treatment for Spider Veins & Thread Veins
Thread veins, also known as spider veins, are extremely common and can affect both men and women of all ages. Whilst they are usually harmless, many people feel self-conscious about the appearance of visible veins on their legs and avoid wearing shorts, skirts or swimwear because of them.
Microsclerotherapy is considered the gold standard treatment for reducing the appearance of thread veins on the legs. Using a series of very small injections, a specialised solution is introduced into the affected veins, causing them to gradually close and fade over the following weeks.
At Aeternum Aesthetics, your treatment is carried out by an experienced nurse prescriber following a comprehensive assessment to ensure microsclerotherapy is the most appropriate treatment for you.

What Can Microsclerotherapy Treat?
Microsclerotherapy is suitable for many superficial thread veins and spider veins affecting the legs, including:
- Red thread veins
- Blue thread veins
- Purple thread veins
- Spider veins
- Small reticular veins
Common treatment areas include:
- Thighs
- Calves
- Behind the knees
- Ankles
If your veins are larger, bulging or associated with symptoms such as aching, swelling or heaviness, further assessment may be required before treatment is recommended.
Your Consultation
Before treatment, you’ll attend a consultation with one of our experienced clinicians.
Where there are signs that could indicate an underlying venous condition, we may recommend further medical or vascular assessment before proceeding. Your safety will always come first.
During your appointment we’ll:
- Discuss your concerns and treatment goals
- Review your medical history
- Examine the affected veins
- Assess your suitability for treatment
- Explain the expected results
- Discuss the likely number of treatments required
- Answer any questions you may have
How Does Microsclerotherapy Work?
Microsclerotherapy involves injecting a prescription sclerosant solution directly into the unwanted thread veins using an extremely fine needle.
The solution irritates the lining of the vein, causing it to collapse and seal closed. Over the following weeks, the body naturally breaks down and absorbs the treated vein, allowing it to gradually fade from view.
Blood is simply redirected through healthy surrounding veins, so circulation is not affected.
What Happens During Treatment?
Treatment is performed in our clinic and usually takes between 30 and 60 minutes, depending on the size of the area being treated.
Using a very fine needle, multiple small injections are placed into the affected veins. Most patients describe the treatment as mildly uncomfortable rather than painful, with a brief stinging sensation during each injection.
Following treatment, compression stockings will be applied, and you’ll be encouraged to remain active by walking immediately afterwards.
Aftercare & Recovery
Following treatment you may experience:
- Mild redness
- Bruising
- Tenderness
- Small raised areas at the injection sites
These effects are temporary and usually settle within a few days. To help achieve the best possible results, you’ll be asked to:
- Wear compression stockings as advised
- Walk regularly following treatment
- Avoid strenuous exercise for the first few days
- Avoid hot baths, saunas and sunbeds during the initial healing period
- Follow your personalised aftercare advice

Frequently Asked Questions
Microsclerotherapy can produce excellent improvements, but no treatment can guarantee complete removal of every visible vein. Some patients require more than one treatment to achieve their desired outcome.
Once a treated vein has been successfully closed, it will not reopen. However, new thread veins can develop elsewhere over time as part of the natural ageing process or due to genetics, hormonal changes or lifestyle factors.
Most patients tolerate treatment very well. You may experience a mild stinging sensation during the injections, but this is usually short-lived.
Yes. We recommend wearing compression stockings after treatment. This is an important part of the healing process and helps to optimise your results. We'll advise exactly how long you'll need to wear them.
Yes. Most patients return to work and normal daily activities immediately after treatment, although you'll need to follow your aftercare instructions carefully.
Results develop gradually as your body naturally absorbs the treated veins. Some veins begin to fade within a few weeks, whilst others can take several months to fully resolve. The number of treatments required varies considerably depending on the number, size and distribution of the veins being treated. During your consultation, we'll provide an honest assessment of what can realistically be achieved and discuss whether additional sessions are likely to be beneficial.
