Sclerotherapy for spider veins is one of the most popular cosmetic vein procedures worldwide. Unlike varicose veins, spider veins are usually smaller, web-like clusters that appear on the legs or sometimes the face. While they are rarely dangerous, many people find them frustrating from an aesthetic perspective. For others, they can cause mild burning or discomfort after long hours of standing.
The treatment itself is straightforward: a medical professional injects a solution into the tiny veins, making them collapse and fade over time. It’s minimally invasive, requires little to no downtime, and produces visible improvements within weeks. No wonder it’s considered the gold standard spider vein treatment in 2025.
How Sclerotherapy Works for Spider Veins
The technique is simple but effective. A fine needle delivers a sclerosant directly into the small, superficial veins. This solution irritates the vein lining, causing the vessel walls to stick together and eventually close. The blood flow naturally reroutes through healthier nearby veins, while the treated spider veins are reabsorbed by the body.
Spider veins often respond quickly because of their small size. Depending on how many clusters a patient has, one to three sessions may be recommended. Each session usually lasts less than 30 minutes, and patients typically walk out and resume normal activities the same day.

Benefits Patients Notice Most
Cosmetic improvement: The most obvious benefit is the visible fading of purple, blue, or red web-like veins.
Quick recovery: Unlike surgery, you won’t need time off work.
High success rate: Multiple studies and decades of use show reliable results for most patients.
Flexibility: Can be repeated if new spider veins appear in the future.
Because spider veins are often linked to genetics, age, hormonal changes, or lifestyle (long standing hours, pregnancy), sclerotherapy is a safe way to manage cosmetic appearance without altering daily routine.
Risks and Side Effects
The good news: side effects are typically mild. Patients may notice temporary redness, slight bruising, or itching at the injection site. Some report small brownish skin discolorations that fade with time. Rarely, matting (tiny new veins) may appear near the treated area, but these often resolve or can be managed with further therapy.
More serious risks—such as deep vein clots or allergic reactions—are very rare when the procedure is done by an experienced vein specialist. Choosing a board-certified physician reduces these risks significantly.

Cost of Spider Vein Treatment
Since spider veins are primarily a cosmetic issue, insurance rarely covers sclerotherapy. The cost of spider vein treatment depends on location and number of sessions, but in the U.S. it typically ranges between $300 and $500 per session. NYC prices may be slightly higher due to clinic overhead and demand.

Recovery and Aftercare
After sclerotherapy, you’ll likely wear compression stockings for a week or two. This supports vein closure and improves cosmetic outcomes. Walking is encouraged, but avoid heavy exercise or sun exposure on the treated area for a few days. Results are not instant—spider veins fade gradually over weeks, with the full effect seen in about two to three months.
In 2025, sclerotherapy for spider veins remains the most effective, minimally invasive way to erase web-like veins that affect confidence and comfort. With short treatment times, little downtime, and consistently positive outcomes, it continues to be the go-to procedure for anyone seeking cosmetic vein relief. For the best results, especially in NYC, consult a qualified vein specialist who can tailor the treatment to your unique situation
