Sclerotherapy: Clear Spider Veins with Injectable Treatment

Sclerotherapy is the most effective treatment for spider veins and small varicose veins. A simple injection causes the vein to collapse and fade — no surgery, no downtime, no scarring.

What Is Sclerotherapy?

Sclerotherapy is the gold-standard treatment for spider veins and small varicose veins. It has been used safely and effectively for over 150 years, with modern formulations providing excellent results with minimal side effects.

During the procedure, a sclerosant solution is injected directly into the targeted vein using a very fine needle. The solution irritates the inner lining of the vein, causing it to swell, stick together, and eventually scar. Over the following weeks, the treated vein fades and is absorbed by the body.

Sclerotherapy can treat both the cosmetic appearance of spider veins and the symptoms associated with small varicose veins, including aching, burning, and itching. Most patients see 50–80% improvement after a single session.

What Sclerotherapy Treats

  • Spider veins on legs, ankles, and feet
  • Small reticular (feeder) veins
  • Small varicose veins
  • Residual veins after ablation
  • Telangiectasias (tiny surface vessels)
  • Veins causing itching or burning
  • Cosmetically bothersome veins

Types of Sclerotherapy

Visual Sclerotherapy

Used for spider veins and small surface vessels visible to the naked eye. The most common form of sclerotherapy, performed with a fine needle and no ultrasound guidance needed.

Best for: Spider veins, telangiectasias

Ultrasound-Guided Sclerotherapy

Uses duplex ultrasound to guide injections into deeper veins not visible on the skin surface. Ideal for treating reticular veins and small varicose veins beneath the skin.

Best for: Reticular veins, small varicose veins

Foam Sclerotherapy

The sclerosant is mixed with air to create a foam that displaces blood and maximizes contact with the vein wall. More effective for larger veins and can be guided by ultrasound.

Best for: Larger varicose veins, recurrent veins

Frequently Asked Questions

What is sclerotherapy?
Sclerotherapy is a minimally invasive procedure in which a sclerosant solution is injected directly into spider veins or small varicose veins. The solution irritates the vein wall, causing it to swell, stick together, and eventually be absorbed by the body, leaving the skin clear and smooth.
Does sclerotherapy hurt?
Most patients describe sclerotherapy as mildly uncomfortable — similar to a small pinch or bee sting. The needles used are very fine, and no anesthesia is required. Most patients tolerate the procedure very well and return to normal activities immediately.
How many sclerotherapy sessions will I need?
The number of sessions depends on the extent of your spider veins. Most patients see significant improvement after 2–4 sessions. Each session treats multiple veins, and sessions are typically spaced 4–6 weeks apart to allow for healing.
Is sclerotherapy covered by insurance?
Sclerotherapy for cosmetic spider veins is typically not covered by insurance. However, when used to treat symptomatic varicose veins or as part of a medically necessary treatment plan, some insurance plans may provide coverage. Our team will review your specific situation.
How long do sclerotherapy results last?
Treated veins are permanently destroyed and will not return. However, new spider veins can develop over time due to genetics, hormones, or lifestyle factors. Maintenance sessions may be recommended to address new veins as they appear.
What is foam sclerotherapy?
Foam sclerotherapy uses a foamed version of the sclerosant solution, which is more effective for larger varicose veins. The foam displaces blood in the vein, allowing greater contact between the sclerosant and the vein wall for more effective closure.
