How Does Sclerotherapy Work?

A fine needle is used to inject a sclerosing solution (Tromboject) directly into the targeted vein. The solution irritates the inner lining of the vessel, causing it to collapse and seal shut. Over the following weeks, the treated vein is gradually reabsorbed by the body and fades from view.

Blood flow is naturally redirected to healthier veins, with no disruption to overall circulation.

The Treatment Process:

1. Consultation During your consultation at Q Dermatology + Aesthetics Centre, your provider will assess the location, size, and severity of your veins and determine the appropriate treatment plan.

2. Treatment The treatment area is cleaned and a fine needle is used to inject the sclerosing agent into each targeted vein. Sessions typically last 30 to 45 minutes depending on the number of veins being treated.

3. Post-Treatment Care Compression stockings (20–30 mmHg) should be worn immediately after treatment and for several days following. Walking is encouraged to promote circulation, while strenuous exercise, hot tubs, saunas, and prolonged sun exposure should be avoided during the initial recovery period.

What To Expect During And After Treatment

During Treatment Most patients experience mild discomfort — a slight stinging or cramping sensation at the injection site that resolves quickly. The procedure is well-tolerated and does not require anesthesia.

After Treatment

• Compression: Wear compression stockings (20–30 mmHg) continuously for 24–48 hours, then during the day for 3–7 days depending on the vein type treated.

• Bruising and Redness: Mild bruising, redness, or raised areas at injection sites are common and typically resolve within a few days to weeks.

• Vein Darkening: Treated veins may temporarily appear darker before fading — this is a normal part of the healing process.

• Minimal Downtime: Most patients return to regular daily activities immediately after treatment. Avoid strenuous exercise for 24–48 hours.

• Sun Protection: Avoid direct sun exposure to treated areas during recovery to prevent post-inflammatory pigmentation.

Important: If you experience sudden swelling, redness extending beyond the injection site, or signs of DVT (deep vein thrombosis) such as significant leg pain or warmth, seek medical assessment promptly.

How Many Sessions Are Needed?

The number of sessions required depends on the extent of the veins being treated. Most patients see noticeable improvement after 2–4 sessions, with results continuing to develop over several weeks as the body reabsorbs the treated vessels.

Sessions are typically spaced 4–6 weeks apart to allow for full healing and assessment of results.

Benefits of Sclerotherapy

— Clinically Proven: The gold standard treatment for spider and reticular veins, with decades of clinical evidence supporting its safety and efficacy.
— Minimally Invasive: No surgery, no general anesthesia, no significant recovery time.
— Precise and Targeted: Each vein is treated individually, ensuring accurate and controlled results.
— Suitable for Multiple Vein Types: Effective for spider veins, reticular veins, and small varicose veins.
— Natural-Looking Results: Veins fade gradually and naturally as the body reabsorbs the treated vessels.
