Spider veins are a common sign that the venous system is under pressure. While many patients seek treatment for cosmetic reasons, a proper evaluation is essential to rule out an underlying venous insufficiency that could worsen over time if left unaddressed.
What Causes Spider Veins?
Understanding the root cause is the first step toward effective, lasting treatment.
The venous system holds up to 70% of the body’s blood volume at any given time. Blood is returned to the heart through a coordinated system of one-way valves and muscle pumps. When vein walls weaken or valves fail, blood pools in the lower extremities under gravity. This increasing pressure causes superficial veins to stretch and dilate, eventually producing the web-like patterns visible on the skin surface. The following risk factors significantly increase your likelihood of developing spider veins:
Family History
Genetics is the single strongest predictor of vein disease. If a parent had spider or varicose veins, your risk is significantly elevated.
Prolonged Standing or Sitting
Occupations requiring long hours on your feet or at a desk increase venous pressure in the lower legs over time.
Advancing Age
Vein walls and valves naturally lose elasticity with age, making venous insufficiency progressively more common after 40.
Excess Body Weight
Additional body weight places greater sustained pressure on the venous system, accelerating valve deterioration.
Pregnancy
Hormonal shifts and increased blood volume during pregnancy place significant strain on leg veins, often triggering first onset.
At CURA Vein Centers in Wayne, NJ, every new patient undergoes a comprehensive evaluation including vascular duplex ultrasound to determine whether an underlying venous insufficiency is driving the appearance of spider veins. Treating surface veins without addressing deeper reflux can result in faster recurrence and suboptimal outcomes.
Primary Spider Vein Treatments in Wayne, NJ
Two highly effective first-line treatments. The right choice depends on your vein size, location, and skin type.
Sclerotherapy
Gold Standard
Sclerotherapy is the most widely recommended and clinically proven treatment for spider veins on the legs. A sclerosant solution is injected directly into targeted veins using an ultra-fine needle under direct visualization or infrared light guidance.
At CURA, we use polidocanol as our preferred sclerosant, recognized as one of the safest and most effective agents available, at concentrations between 0.25% and 1% depending on the size of the treated vein. The solution disrupts the vein wall lining, causing it to collapse and seal. Over the following two to eight weeks, the treated vein is gradually broken down and reabsorbed by the body.
A single session typically produces 50 to 60% improvement. Most patients achieve full clearance after two or three treatments, with no anesthesia and no downtime required.

Laser Therapy
Fine Veins
Laser treatment uses a precisely focused beam of light energy that is selectively absorbed by hemoglobin within the blood vessel. The resulting heat causes the vein to contract and close, after which the body gradually clears it over several weeks.
Laser therapy is particularly well suited for very fine spider veins, those located in difficult-to-inject areas such as around the ankle or foot, or in patients who prefer to avoid needles entirely. It is also an excellent option for individuals with sensitivity to injectable sclerosant agents.
Multiple sessions may be required for complete clearance, and mild redness or temporary skin discoloration can occur in the treated area during the healing process.

Frequently Asked Questions
Common questions about spider vein treatment in Wayne, NJ answered by our specialists.
There is no single universal answer, as it depends on the size, location, and depth of the veins being treated, as well as individual patient factors. Sclerotherapy is generally preferred for spider veins on the legs due to its proven efficacy and ability to treat multiple veins per session. Laser therapy is better suited for very fine veins or those in areas difficult to inject. At CURA, your physician will assess both options and recommend the most appropriate treatment for your specific presentation.
One sclerotherapy session typically produces 50 to 60% improvement in the treated area. Most patients with moderate spider vein involvement achieve full clearance after two to three sessions, spaced four to six weeks apart. Patients with more extensive vein networks may require additional sessions. Your physician will give you a realistic timeline during your initial consultation based on the extent of your veins.
Most patients describe sclerotherapy as mildly uncomfortable rather than painful, similar to a light pinprick for each injection. Laser treatments produce a brief sensation of warmth or snapping at the skin surface. Neither procedure typically requires anesthesia. Any mild redness, bruising, or swelling in the treated area generally resolves within one to two weeks.
Purely cosmetic spider vein treatments are generally not covered by insurance. However, if your spider veins are associated with documented symptoms such as leg pain, swelling, or heaviness, or if an underlying venous insufficiency is identified on ultrasound, the evaluation and any medically necessary treatment may be covered by your plan. Our team at CURA will verify your benefits upfront so you know exactly what to expect before any procedure.
Treated veins are permanently closed and do not return. However, new spider veins can develop over time if the underlying risk factors remain present, including genetics, hormonal changes, or prolonged standing. Wearing compression stockings, staying active, and maintaining a healthy weight can help slow the development of new veins after treatment.
For sclerotherapy, avoid applying lotion or oil to your legs on the day of treatment and wear loose, comfortable clothing. You may be advised to avoid certain medications such as blood thinners or anti-inflammatory drugs in the days before your appointment. For laser treatments, avoid sun exposure to the treatment area for at least two weeks prior. Your physician will provide a full pre-treatment checklist at your consultation.
