Sclerotherapy
The gold standard treatment for spider veins and small varicose veins.
Sclerotherapy injections target small varicose veins (often referred to as spider veins), most often found on the legs. The treatment works by injecting the veins with a solution that will irritate the vein and cause inflammation, ultimately resulting in the vein collapsing and disappearing.
What is Sclerotherapy?
Sclerotherapy is a proven, minimally invasive medical procedure that has been used for decades to eliminate unsightly reticular and spider veins. This FDA-approved treatment is considered the gold standard for treating these common vascular conditions, offering patients an effective solution to achieve smoother, clearer-looking legs.
The procedure involves the precise injection of a specialized sclerosing solution directly into the targeted veins. This solution causes the vein walls to become irritated and inflamed, leading them to stick together and eventually collapse. Over time, the treated veins are naturally absorbed by the body and fade from view, leaving behind smoother, more attractive skin.
After consulting with a provider, our office will customize a treatment plan that is right for you based on the number and size of the veins. Some patients may require more than one session to achieve optimum results. The number of sessions you may need will also be discussed in your consultation. Expectations and aftercare/post-treatment instructions will also be discussed.
Understanding Spider Veins and Varicose Veins
Spider Veins (Telangiectasias) Spider veins are small, damaged veins that appear close to the skin’s surface. They typically appear as thin, web-like clusters of red, blue, or purple lines and are usually less than 1mm in diameter. Common characteristics include:
- Fine, thread-like appearance
- Often found on legs, thighs, calves, and ankles
- Usually painless but can cause cosmetic concerns
- More common in women than men
Small Varicose Veins (Reticular Veins) These are slightly larger than spider veins, typically 1-3mm in diameter, and appear as blue or green veins just beneath the skin’s surface. They often feed into spider veins and may cause:
- Aching or burning sensations
- Leg fatigue
- Restless legs
- Cosmetic concerns
Causes and Risk Factors
Primary Causes:
- Heredity: Family history is the most significant risk factor
- Hormonal Changes: Pregnancy, menopause, and hormonal medications
- Age: Vein valves weaken over time
- Gender: Women are more susceptible due to hormonal factors
Contributing Factors:
- Prolonged standing or sitting
- Pregnancy and multiple pregnancies
- Weight gain
- Lack of physical activity
- Sun exposure (for facial spider veins)
- Tight clothing that restricts circulation
- High-impact activities that stress leg veins
How Sclerotherapy Works

The Science Behind Treatment:
- Injection: A fine needle delivers sclerosing solution directly into the vein
- Irritation: The solution irritates the vein lining (endothelium)
- Inflammation: The vein walls become inflamed and stick together
- Closure: The vein collapses and seals shut
- Absorption: Over weeks to months, the body naturally absorbs the treated vein
- Results: The vein fades and eventually disappears
Treatment Areas

Leg Areas:
- Thighs (inner and outer)
- Calves
- Ankles
- Feet
- Behind the knees

FAQ's
How painful is sclerotherapy?
Most patients describe the discomfort as minimal, similar to a small pinprick. The sclerosing solution may cause a mild burning sensation that lasts only seconds.
How many treatments will I need?
The number of treatments varies based on the extent of your veins. Most patients need 2-4 sessions spaced 4-6 weeks apart for optimal results.
When will I see results?
Some veins fade immediately, but full results typically take 2-6 months to appear as the body gradually absorbs the treated veins.
Can treated veins come back?
Once a vein is successfully treated with sclerotherapy, it cannot return. However, new spider veins may develop over time due to genetics and lifestyle factors.
Is there any downtime?
There’s minimal downtime. You can return to normal activities immediately, though strenuous exercise should be avoided for 24-48 hours.
Can I have sclerotherapy while pregnant?
Sclerotherapy is not recommended during pregnancy or while breastfeeding. It’s best to wait until after childbirth and breastfeeding are complete.
Will insurance cover sclerotherapy?
Sclerotherapy for cosmetic spider veins is typically not covered by insurance. However, treatment for symptomatic varicose veins may be covered if medically necessary.
What's the difference between sclerotherapy and laser treatment?
Sclerotherapy is generally more effective for spider veins and is considered the gold standard. Laser treatments are typically reserved for very small surface veins or as a complementary treatment.
