Spider Veins

What is Sclerotherapy?

Sclerotherapy is a minimally invasive procedure that reduces the appearance of spider veins and reticular veins, the fine red, purple, and blue vessels that often show through the skin surface of the legs. Spider veins and varicose veins affect roughly 30 to 60 percent of adults. Genetics play the largest role, and visible veins tend to become more prominent with aging, pregnancy, menopause, hormone replacement therapy, and jobs that keep you on your feet for long hours.

During this medical procedure, your provider uses a very fine needle to inject small amounts of a sclerosing solution directly into each vein in the targeted area. The solution irritates the inner lining of the vein walls, causing the vessel to collapse on itself and close. Over the following weeks, the body gradually absorbs the treated veins, while blood flow continues through healthy veins beneath the skin. The result is smoother, clearer-looking legs without surgery or anesthesia.

Why Choose UnionDerm for Spider Vein Treatment?

Treating spider veins successfully depends on more than the injection itself. It requires a clear understanding of vein anatomy, an eye for which vessels will respond best, and the judgment to know when a combination approach will deliver a better outcome. At UnionDerm, every patient begins with a consultation and leaves with a personalized treatment plan built around the size, color, and location of their veins.

Certain red and blue veins also respond well to light-based therapy. When both large and small vessels are present on the legs, our physicians often pair sclerotherapy with vascular laser treatments for the most complete improvement. This combination approach is one of the reasons our patients see such consistent results from their vein treatment.

UnionDerm is home to an active clinical research department and an ASDS Fellowship in Cosmetic Dermatology, which keeps our team current on evidence-based techniques. You can learn more about the experience behind your care when you meet our doctors.

What to Expect During the Sclerotherapy Procedure

Sclerotherapy is easy to perform in the office, and no anesthesia is required. To begin, the skin surface over the targeted area is cleansed. Your provider then injects the solution into each vein using a very fine needle, working methodically across the leg. Most patients describe the sensation as a brief pinch or mild sting with each injection.

The length of your appointment will depend on how many veins are being treated. Once your session is complete, you can get up, walk around, and head back to your day.

How Many Treatments Will I Need?

One of the most common questions we hear is how many treatments it will take to clear visible veins. The answer depends on the number, size, and depth of the veins being addressed. Our patients get the best results from a series of treatment sessions, spaced several weeks apart to give the body time to absorb the treated veins between visits.

Smaller spider veins often fade within a few weeks, while larger vessels can take a few months to fully resolve. Most patients can see visible improvement within 2-4 weeks after treatment. Because new veins can develop with age, many patients return for occasional maintenance sessions to keep their legs looking clear over time.

Recovery and Aftercare

Sclerotherapy offers minimal downtime, and most patients return to work and their normal routine the same day. Walking is encouraged after treatment, as it helps keep blood moving through healthy veins.

Your provider may recommend wearing a compression stocking for about one week after your session to support the treated veins as they close. You may also be advised to avoid strenuous exercise, hot baths, saunas, and prolonged sun exposure for a short period. Mild bruising, redness, or small raised areas at the injection sites are common and typically fade within a few days.

Can sclerotherapy treat varicose veins?

Sclerotherapy is designed primarily for spider veins and reticular veins. Some smaller varicose veins may also respond to treatment. Larger, bulging varicose veins, or veins that cause aching, swelling, or heaviness, may require evaluation by a vein specialist before cosmetic treatment.

Does sclerotherapy hurt?

Most patients tolerate the sclerotherapy procedure very well. Because a very fine needle is used, each injection feels like a quick pinch or mild sting, and no anesthesia is needed.

When will I see results?

Smaller spider veins typically begin to fade within a few weeks. Larger veins may take a few months to disappear as the body gradually absorbs them.

Do I need to wear compression stockings after treatment?

Many patients are asked to wear a compression stocking for a short time after treatment. Compression helps the treated veins stay closed and can support faster healing. Your provider will give you specific instructions at your visit.

Will my spider veins come back?

Veins that are successfully treated do not return. However, sclerotherapy does not prevent new veins from forming, especially since genetics and aging play such a large role. Periodic maintenance treatments can help keep new visible veins under control.

Is there any downtime?

Sclerotherapy is known for minimal downtime. Most people walk out of the office and resume their daily activities right away, with only a few short-term precautions to follow.
