Quick answer
Spider veins are the thin red lines and web-like clusters that show up on your legs, feet or face. They are smaller than varicose veins and rarely dangerous, though they can ache or burn after you have been standing a while. Most people treat them for looks. Sclerotherapy injects a solution that closes the vein so it fades over a few weeks. Laser therapy uses light instead, with no needles.
Spider veins are thin red lines or web-like networks of blood vessels that appear on your legs and feet. These veins typically develop on the legs or face and can range from tiny clusters to more prominent networks.
While typically harmless, they can sometimes cause aching, burning, or pain, especially if you’ve been standing for long periods. That’s why we recommend you seek treatment if they cause discomfort or if you are unhappy with their appearance. Treatment options for spider veins include sclerotherapy, laser therapy, and some lifestyle changes, and on average, they cost $300-$3,000.
Causes and Risk Factors of Spider Veins

One of the main reasons for spider veins is weak or damaged veins. This is because damaged veins fail to push blood efficiently, causing blood to pool and create visible spider veins. It could also happen due to poor blood flow or circulation. When there is inefficient circulation, especially in the leg veins, it leads to pressure buildup in the smaller veins.
Genetics is another cause of spider veins, as a family history of varicose veins or spider veins increases the likelihood of developing these conditions. Furthermore, hormonal changes from pregnancy, menopause, or the use of birth control pills can affect blood vessels and increase the risk of developing spider veins.
Generally, as people age, the vein valves weaken. This causes blood to pool in the veins and contributes to the formation of both varicose veins and spider veins. People who stand or sit for long periods are also at a greater risk of developing spider veins as blood pools in the leg veins, leading to both small varicose veins and spider veins. Moreover, excessive sun exposure can weaken the small blood vessels near the skin’s surface and lead to spider veins, especially on the face.
Typically, people with larger varicose veins are at a higher risk of developing spider veins. Likewise, people with conditions like superficial vein thrombosis or deep vein thrombosis (DVT) are also at risk of developing spider veins. These conditions may cause blood clots in the legs and increase the likelihood of spider veins. Similarly, obese people are also at risk as excess weight puts added pressure on the leg veins. This disrupts blood flow and leads to both varicose veins and spider veins.
Varicose Veins vs. Spider Veins
Varicose veins are larger, bulging veins that often occur alongside spider veins. They are more likely to cause serious health issues like deep vein thrombosis (DVT) or superficial vein thrombosis, leading to blood clots and potential complications like pulmonary embolism. In contrast, spider veins are smaller and rarely pose health risks.
Treating varicose veins may involve more aggressive approaches like endovenous laser therapy, vein surgery, or radiofrequency ablation, while spider veins often require less invasive treatments like sclerotherapy or laser therapy. Varicose veins pose a more serious concern and need invasive procedures. However, since spider veins are mostly seen as a cosmetic issue, less invasive treatments are suitable.
For any vein treatment, a physical exam and a medical history review by a healthcare provider are important to prevent complications and ensure effective treatment. This way, they get to come up with personalized treatment plans for you.
Treatment for Spider Veins

For those concerned about the appearance of spider veins, there are multiple forms of treatment available. One such treatment is Sclerotherapy. This involves the doctor injecting the veins with a chemical solution that scars and closes those veins, causing the blood to reroute through healthier veins. The treated spider veins fade within a few weeks. The same vein may need to be injected more than once, but sclerotherapy is usually effective if done correctly.
A second treatment option is laser surgery, which works by sending strong bursts of light or radiofrequency energy into the vein that make the vein slowly fade and disappear. No incisions or needles are used. The treatment is often less effective than sclerotherapy, particularly for larger veins. Side effects may include redness, bruising, itching, swelling, and permanent skin tone changes. After treatment, blood vessels fade over several months, but they may not disappear completely. Also, new spider veins can develop in the same area.
Another common treatment option is to wear compression stockings. Wearing compression stockings can improve blood flow in leg veins and help prevent the formation of new spider veins. Support stockings reduce pressure on blood vessels, minimizing blood pooling in the legs. This is particularly useful for those who spend long periods standing or sitting.
However, for larger varicose veins, endovenous laser therapy (EVLT) or endovenous laser ablation may be used. For this varicose vein treatment, a laser fiber is inserted into the affected vein, and laser energy closes the vein. This is an effective option for treating both larger varicose veins and some spider veins. The treated leg typically heals within a few weeks, and blood flow is redirected to healthy veins.
Vein surgery is another treatment option for larger varicose veins and spider veins. This involves removing or tying off the affected vein to improve blood flow and prevent blood clots or pulmonary embolism. Surgery is often reserved for severe cases or when other treatments fail.
Furthermore, lifestyle changes including good skin hygiene, weight loss (if needed), and walking can help treat varicose veins and spider veins. Wearing properly-fitting support stockings may also help, especially when the veins cause painful or uncomfortable symptoms.
Want To Get Spider Vein Treatment?
Spider veins, though primarily a cosmetic issue, can also indicate underlying circulation problems. If left untreated, they may lead to discomfort and potential complications such as blood clots. Fortunately, there are several effective treatment options available, including compression stockings, sclerotherapy, laser therapy, and endovenous laser therapy (EVLT). These treatments improve blood flow, reduce visible veins, and prevent the formation of new spider veins. Early intervention is key to avoiding future issues.
