The injections are almost painless – you may feel a slight pricking sensation as the injections are being performed.

After treatment the skin around the vein may appear pink and blotchy, and a small bruise may be visible at the site of treatment.

The veins may look worse immediately after treatment and large blood vessels may become darker in colour. The veins will start to fade after 3 weeks and it will take 3 months before the full results of the procedure are seen.

Complications from the treatment are rare but can include venous thromboembolism, visual disturbances, allergic reaction and hyperpigmentation.

If the solution is injected properly into the vein, there is no damage to the surrounding skin, but if it is injected outside the vein scarring can occur.

Your practitioner will discuss the procedure and possible side effects with you in detail during your free consultation.
