posted in: Varicose Veins

Thread veins, also known as spider veins, represent one of the most common vascular conditions, affecting a significant portion of the population. Characterised by their small, web-like appearance on the skin, these veins are more than just a cosmetic concern for many. They often indicate underlying circulatory issues and can significantly impact an individual’s self-esteem and quality of life.

Choosing the proper treatment for thread veins is crucial, as it addresses the aesthetic aspect and caters to each individual’s unique vascular health needs. A thorough vascular consultation is vital, offering a tailored approach that considers your thread veins’ specific characteristics and severity. This initial assessment paves the way for selecting the most effective treatment method, microsclerotherapy, laser treatment, or a combination of both, ensuring optimal results and patient satisfaction.

Microsclerotherapy vs. Laser Treatment for Thread Veins - Veins Solutions


Thread Veins

Thread veins, medically known as telangiectasia, are small, dilated blood vessels that appear close to the skin’s surface. Typically measuring only a few millimetres in diameter, these veins often present red, blue, or purple lines resembling a spider’s web or tree branches. While they can occur anywhere on the body, they are most commonly seen on the legs and face.

The causes of thread veins are multifaceted, involving genetic and lifestyle factors. Key contributors include:

  • Genetics:
    A family history of thread veins significantly increases the likelihood of developing them.
  • Age:
    As the skin ages and becomes thinner, thread veins become more visible.
  • Hormonal Changes:
    Hormonal fluctuations during pregnancy, menopause, or due to contraceptive pills can contribute to their development.
  • Sun Exposure:
    Prolonged sun exposure can damage the skin and blood vessels, leading to thread veins, especially on the face.
  • Lifestyle Factors:
    Standing or sitting for extended periods, obesity, and lack of exercise can all impact vein health.
  • Other Medical Conditions:
    Certain medical conditions, such as rosacea, can also predispose individuals to thread veins.

The presence of thread veins can profoundly impact an individual’s aesthetics and psychological well-being. While they are generally not associated with serious health risks, their visibility can lead to:

  • Cosmetic Concerns:
    Many individuals feel self-conscious about the appearance of thread veins, particularly when they are on visible areas like the face or legs.
  • Reduced Confidence:
    The visibility of these veins can affect a person’s confidence, influencing their clothing choices and social participation.
  • Psychological Impact:
    In some cases, persistent thread veins can lead to anxiety and decreased self-esteem, especially if they are seen as a significant cosmetic flaw.



Microsclerotherapy is a minimally invasive medical procedure designed specifically to treat thread veins. This technique involves injecting a sclerosing agent, a special solution, directly into the affected veins using a very fine needle. The procedure is typically performed in an outpatient setting and does not require anaesthesia, as it causes minimal discomfort.

The process is meticulous and requires precision. A practitioner will carefully target each thread vein individually. The number of injections in a single session depends on the number and size of the veins being treated. Each session usually lasts 30 minutes to an hour, and patients may require multiple sessions to achieve the desired results.

The sclerosing agent used in microsclerotherapy irritates the lining of the targeted veins. This irritation causes the walls of the veins to stick together, effectively closing the vein. Once the vein is closed, blood is rerouted to healthier veins. The treated vein, now devoid of blood flow, becomes scar tissue and gradually fades from view over time.

This mechanism of action is particularly effective for thread veins due to their size and superficial nature. The solution used in microsclerotherapy is formulated to be effective on these small, surface-level veins, ensuring a high success rate in their closure and eventual disappearance.

Microsclerotherapy is highly regarded for its precision and effectiveness, making it one of the most sought-after treatments for the aesthetic elimination of unsightly thread veins.



Benefits and Limitations of Microsclerotherapy

Microsclerotherapy is widely recognised for its high efficacy in treating thread veins. This procedure is particularly adept at targeting and eliminating these small, superficial veins, often yielding significant cosmetic improvements. Clinical evidence and patient reports consistently support its success, with many patients observing substantial reduction or complete disappearance of treated veins. The precision of this method allows for targeted treatment, making it ideal for addressing specific areas with thread veins.

While microsclerotherapy is generally safe, there are some common side effects that patients should be aware of:

  • Bruising and Swelling:
    The most common side effects are temporary bruising and swelling at the injection sites, which typically subside within a few days to a week.
  • Discoloration:
    Some patients may experience temporary skin discolouration over the treated veins, which usually fades over time.
  • Mild Discomfort:
    A slight stinging or burning sensation during the injection is common, but it is usually brief and tolerable.
  • Matting:
    In rare instances, tiny new blood vessels may develop near the treated area, known as matting, which can be addressed in subsequent sessions.

Not all patients are ideal candidates for microsclerotherapy, and certain criteria should be considered:

  • Vein Size:
    Microsclerotherapy is most effective on small to medium-sized thread veins and may not be suitable for larger varicose veins.
  • Medical History:
    Patients with a history of allergic reactions to sclerosing agents or certain underlying health conditions may not be suitable for this treatment.
  • Pregnancy and Breastfeeding:
    The treatment is generally not recommended for pregnant or breastfeeding women.
  • Mobility:
    Good mobility can enhance recovery, as regular movement post-treatment is encouraged to facilitate circulation and prevent complications.
  • Skin Condition:
    Active skin infections or certain dermatological conditions in the treatment area may contraindicate the procedure.

In summary, microsclerotherapy offers a highly effective solution for the aesthetic treatment of thread veins, with a generally well-tolerated side effect profile.


Laser Treatment

Laser treatment for thread veins significantly advances cosmetic and dermatological care, offering a non-invasive alternative to traditional methods like microsclerotherapy. This technology harnesses the power of focused light energy to target and eliminate thread veins. The procedure involves directing a laser beam at the affected veins, which absorbs the light and collapses without damaging the surrounding tissue.

The technological basis of laser treatment lies in its ability to target the pigment in the blood vessels selectively. The laser emits specific wavelengths of light that are preferentially absorbed by the haemoglobin in the blood. This absorption generates heat, causing the blood within the veins to thicken and the vessel walls to collapse. Over time, the body reabsorbs these damaged veins, reducing or eliminating the visible thread veins.

Various laser systems are employed in treating thread veins, differing in their wavelength, energy output, and application method. One notable system Vein Solutions uses is Veinwave, a specialised technology designed for treating thread veins.

  • Veinwave Technology:

Veinwave utilises a unique thermocoagulation process, which involves the application of high-frequency energy to the skin above the vein. This method is particularly effective in treating extraordinary thread veins, often seen on the face and legs, that are difficult to address with traditional sclerotherapy. The precision of Veinwave allows for targeted treatment with minimal risk of skin injury or pigmentation changes.

  • Nd:YAG Lasers:

Another common type of laser used in thread vein treatment is the Nd: YAG laser. This laser operates at a wavelength that penetrates deeper into the skin, making it practical to treat more prominent thread veins beneath the skin’s surface.

  • Pulsed Dye Lasers:

These lasers emit different wavelengths of light, which is highly effective in treating thread veins closer to the skin’s surface. Pulsed dye lasers are known for their precision and are often used for facial vein treatment.

Benefits and Limitations of Laser Treatment

Laser treatment is highly effective for a wide range of thread veins, particularly those that are difficult to treat with conventional methods like microsclerotherapy. It is especially advantageous for treating small, fine-thread veins close to the skin’s surface, such as those on the face. The technology is versatile enough to target different sizes and depths of veins, with various lasers available to treat specific vein characteristics.

  • Facial Veins:
    Laser treatment excels in treating facial spider veins, offering precision and minimal risk of scarring or skin pigmentation changes.
  • Leg Veins:
    For leg spider veins, lasers can effectively target and diminish these veins, though larger varicose veins may require alternative treatments.

While laser treatment for thread veins is generally safe, there are some potential side effects that patients should be aware of:

  • Skin Reactions:
    Temporary redness, swelling, and itching at the treatment site are common immediately after the procedure.
  • Pigmentation Changes:
    There is a small risk of temporary hyperpigmentation (darkening) or hypopigmentation (lightening) of the skin in the treated area.
  • Discomfort:
    Some patients may experience mild discomfort during the procedure, similar to the sensation of a rubber band snapping against the skin.

Laser treatment for thread veins is not suitable for everyone, and certain factors need to be considered:

  • Skin Type:
    Individuals with darker skin tones may have a higher risk of pigmentation changes due to the laser’s interaction with melanin in the skin.
  • Sun Exposure:
    Recent sun exposure can increase the risk of skin reactions, so patients are advised to avoid tanning before treatment.
  • Medical Conditions:
    Certain medical conditions, such as a history of keloid scarring or photosensitivity, may contraindicate laser treatment.
  • Medications:
    Some medications, particularly those that increase photosensitivity, may affect the suitability of laser treatment.

Laser treatment offers a compelling alternative for removing thread veins, particularly for patients seeking a non-invasive option with minimal downtime.


Comparing Microsclerotherapy and Laser Treatment

Microsclerotherapy is highly effective for small to medium-sized thread veins, particularly on the legs. It is ideal for veins that are not too superficial, where the sclerosing agent can work effectively.

Laser Treatment, including technologies like Veinwave, is particularly suited for fine thread veins, especially on the face, where microsclerotherapy might be less effective. The precision of laser treatments also makes them a good choice for thread veins in sensitive areas.

Recovery Time and Patient Comfort

Microsclerotherapy typically involves minimal downtime, with patients able to resume normal activities shortly after treatment. Some bruising and swelling may occur, requiring using compression stockings for a short period.

Laser Treatment generally offers a quicker recovery time, with less bruising than microsclerotherapy. The procedure may cause some discomfort, akin to a snapping sensation, but is usually well-tolerated.

Long-Term Results and Recurrence Rates

Both treatments provide long-lasting results, but neither can prevent the formation of new thread veins due to factors like ageing or genetics.

Microsclerotherapy may have a slightly higher recurrence rate, as targeting every tiny vein in a session is challenging.

Laser Treatments may offer a more permanent closure of the treated veins, though multiple sessions might be required for optimal results.
