Spider veins are a common cosmetic concern that can affect confidence and comfort alike. While they are usually harmless, these fine red, blue, or purple veins can appear on the legs or face and may sometimes cause mild discomfort.
At Vein Doctors Sydney, we offer evidence-based, minimally invasive options to help you achieve smoother, clearer skin. Two of the most effective treatments are sclerotherapy and laser therapy for spider veins. But which option is right for you? Below, we explore how each treatment works, the benefits and key differences to help guide your decision.
Understanding Spider Veins
Spider veins, also called telangiectasias, are small, dilated blood vessels that appear close to the surface of the skin. They are usually red, blue, or purple and can form web-like clusters or fine lines. They develop when the tiny valves inside veins weaken, allowing blood to pool rather than flow efficiently back to the heart.
Although they do not usually cause medical complications, they can indicate early signs of venous insufficiency. Recognising them early allows you to consider safe, effective treatment options before they worsen or spread.
Sclerotherapy for Spider Veins
Sclerotherapy is one of the most established and effective treatments for leg spider veins. During the procedure, a medical-grade solution is injected into the affected veins using a very fine needle. This causes the vein walls to stick together and collapse, eventually being reabsorbed by the body. Over several weeks, the treated veins fade from view.
Most treatments take around 30 minutes and involve little discomfort. You may be advised to wear compression stockings afterwards to support vein healing and circulation.
Laser therapy uses concentrated beams of light to treat spider veins without injections.
Advantages of Sclerotherapy
- Highly effective for leg spider veins and small varicose veins
- Treats multiple veins in one session
- Minimal recovery time; patients can return to daily activities quickly
- Long-lasting results when combined with healthy habits
Disadvantages of Sclerotherapy
- Requires small injections, which may not be suitable for needle-sensitive patients
- Temporary redness, bruising, or mild itching may occur
- Not ideal for very fine facial veins
Laser Therapy for Spider Veins
Laser therapy, also known as laser vein removal, uses concentrated beams of light to treat spider veins without injections. The laser’s energy heats and collapses the targeted vein, which is then naturally absorbed by the body.
This treatment is especially useful for small or delicate veins, such as those on the face, nose, or chest, where injections may not be practical. Each session lasts around 15 to 30 minutes, and most people resume normal activities immediately.
Advantages of Laser Therapy
- Non-invasive and needle-free
- Excellent for small, surface-level or facial veins
- Quick sessions with minimal downtime
- Safe for patients with allergies to injectable solutions
Disadvantages of Laser Therapy
- May require several sessions for optimal results
- Mild redness or sensitivity can occur after treatment
- Less effective for larger leg veins compared to sclerotherapy
There are several differences between sclerotherapy and laser therapy, including the technique used, treatment time, sessions needed and more.
Sclerotherapy vs Laser Therapy for Spider Veins: Comparison Table
| Feature | Sclerotherapy | Laser Therapy |
|---|---|---|
| Technique | Medical-grade solution injected into the vein | Concentrated light energy targets and closes veins |
| Best For | Leg spider veins and small varicose veins | Small facial veins or surface-level spider veins |
| Treatment Time | 30 minutes per session | 15 to 30 minutes per session |
| Comfort Level | Mild sting or pressure at injection sites | Warm or tingling sensation on the skin |
| Sessions Needed | One to three, depending on severity | Two to five, depending on vein size and depth |
| Downtime | Minimal – compression stockings recommended | Minimal – avoid direct sun exposure temporarily |
| Results Visible | 3 – 6 weeks after treatment | 4 – 8 weeks after treatment |
| Longevity | Long-term results, treated veins rarely return | Long-term, fine veins may reappear over time |
Recovery and Aftercare
Both treatments are performed as outpatient procedures, so you can return home the same day without the need for a hospital stay.
After sclerotherapy, you may be advised to wear compression stockings for several days. These support the treated veins as they close, minimise swelling and promote healthy circulation. Mild redness or light bruising can occur around the injection sites, although this usually settles within a few days. Gentle walking is encouraged soon after treatment to maintain good blood flow.
After laser therapy, sun protection becomes particularly important as the treated areas may be more sensitive to light. Avoiding hot baths, saunas, and direct sun exposure for the first few days can help prevent pigmentation changes and allow the skin to settle comfortably.
Whichever treatment you have, strenuous exercise and high-impact activities should be avoided for 24 to 48 hours. Any mild discomfort, swelling, or temporary skin sensitivity typically improves as your body naturally clears the treated veins.
Combining Treatments for Optimal Results
Some patients benefit most from combining both treatments. For example, sclerotherapy can target larger leg veins, while laser therapy can address smaller surface veins or fine facial capillaries.
At Vein Doctors Sydney, our specialists personalise every treatment plan, ensuring you receive the safest and most effective results. We may also recommend complementary therapies such as compression stockings or procedures like Endovenous Laser Ablation (EVLA) for larger or more complex vein conditions.

Frequently Asked Questions
Does sclerotherapy or laser therapy hurt?
Both treatments are well tolerated. Sclerotherapy may feel like a mild sting during injections, while laser therapy can feel warm or tingling. Discomfort is brief and minimal.
How long do results last?
Treated veins are permanently closed and absorbed by the body. However, new veins can develop over time, especially if you have a family history or a prolonged standing job.
Can spider veins come back after treatment?
Treated veins do not return, but new ones may form. Regular exercise, maintaining a healthy weight and avoiding long periods of standing can reduce recurrence.
Is laser therapy better than sclerotherapy?
Each has its strengths. Sclerotherapy is ideal for leg veins, while laser therapy is better suited for facial or smaller surface veins. Your vein specialist can recommend which is best for your needs.
What is the recovery time after treatment?
Most people resume normal activities immediately. Mild redness, swelling, or bruising can occur but typically resolves within days.
Can I combine sclerotherapy and laser therapy?
Yes. Many patients see the best results when combining both treatments, especially for veins of different sizes or depths. This approach provides more comprehensive clearance.
