Thread Vein Treatments

Clinical assessment and sclerotherapy management of superficial telangiectasia

Telangiectasia (thread veins or spider veins) are dilated superficial venules commonly presenting on the lower extremities. At Berkshire Aesthetics, our medical assessment includes evaluation of underlying venous competence before recommending microsclerotherapy — a clinically validated, minimally invasive procedure to occlude and resorb visible surface vessels.

Aetiology & Contributing Factors

  • Genetic predisposition — thread veins often run in families
  • Hormonal influences, particularly oestrogen (pregnancy, contraception, menopause)
  • Prolonged standing or sitting, especially in occupations requiring extended periods on your feet
  • Age-related weakening of vein walls and valves
  • Sun exposure, particularly on the face
  • Obesity or excess body weight increasing venous pressure
  • Previous deep vein thrombosis or venous insufficiency

Clinical Presentation

  • Fine, visible red, blue or purple veins on the legs, typically on the thighs, calves or ankles
  • Web-like or branching patterns of small surface veins
  • Occasionally associated with aching, heaviness or discomfort in the legs
  • May worsen over time without treatment
  • Can cause self-consciousness, particularly in warmer months

Evidence-Based Treatment Modalities

Treatment selection is individualised following clinical assessment, taking into account disease severity, Fitzpatrick skin type, medical history and patient goals.

Microsclerotherapy

Microsclerotherapy involves injecting a sclerosing solution directly into thread veins using a very fine needle. The solution irritates the vein lining, causing it to collapse and gradually be reabsorbed by the body. Over the following weeks, the treated veins fade from view.

Why we start with a consultation

Every treatment begins with a medical assessment. We need to understand your medical history, current health, skin condition and concerns before prescribing any procedure. This protects your safety and ensures the treatment is clinically appropriate for you.

During your consultation, Dr Langdon will explain what the treatment can realistically achieve, any risks specific to you, and whether an alternative might be more appropriate.

Clinical FAQs: Thread Veins

Microsclerotherapy is a minimally invasive procedure where a sclerosing solution is injected into thread veins, causing them to collapse and gradually fade. It is the gold-standard treatment for leg thread veins.
Most patients require 2–4 sessions spaced 6–8 weeks apart to achieve optimal results. The number depends on the extent and distribution of your thread veins, assessed during consultation.
Most patients describe a mild stinging or pricking sensation during injections. The needles used are very fine, and treatment is generally well-tolerated without anaesthetic.
You are encouraged to walk immediately after treatment and resume normal activities. Compression stockings are typically worn for 1–2 weeks. Strenuous exercise, hot baths and sun exposure should be avoided during this period.
Treated veins typically begin to fade over 4–8 weeks. Full results may take 2–3 months to develop. Some veins may require retreatment at a follow-up session.
Treated veins do not return, but new thread veins can develop over time due to underlying predisposing factors. Maintenance sessions may be needed to address new veins as they appear.
Microsclerotherapy is primarily used for leg thread veins. Facial thread veins may be treated with alternative methods. Your doctor will advise the best approach during your consultation.

Clinical Summary

Expected Recovery PeriodMinimal — normal activities can be resumed immediately; compression stockings worn for 1–2 weeks; avoid strenuous exercise and heat for the compression period
Therapeutic ResponseTreated veins begin fading within 4–8 weeks; full results typically visible after 2–3 months; additional sessions may be needed for optimal clearance

Clinical Governance

  • Microsclerotherapy is performed by experienced doctors who assess the underlying cause and ensure there is no significant venous insufficiency before treatment
  • We use a proven, minimally invasive technique with a strong evidence base for treating leg thread veins
  • Realistic expectations are set during consultation — we explain the typical results, the number of sessions likely needed and any limitations
