Asclera is an FDA-approved injectable drug used during sclerotherapy treatments to diminish the appearance of spider veins (<1mm) and small varicose veins (1-3mm) found in the legs and ankles. This non-surgical, cosmetic treatment must be administered by a healthcare  provider. It removes damaged veins permanently.

Asclera damages the inner lining of the veins, causing platelet clots to form within the vessels. Once the vein is closed up, the blood gets rerouted to healthier veins, and the body absorbs the damaged vein. The procedure is safe and delivers effective long-term results.

Before the treatment begins, patients can request a local anesthetic. The procedure lasts anywhere from 15 to 45 minutes. The time depends on the number and size of veins that need to be treated. Before injecting Asclera into the site, the area is cleaned and  disinfected. The procedure usually requires multiple injections as each injection only targets a part of the vein. Once Asclera is injected, the targeted veins will clot, break down, and fade away within the next few weeks. To prevent blood clots from forming in other vessels, patients will need to walk for 15-20 minutes right after the treatment. They need to continue to do so every day for the next several days.

After the procedure, patients must wear a compression stocking for the next few days; 2-3 days for the spider veins treatment and 5-7 days for varicose veins. This will encourage healthy blood circulation and a quick recovery. There may be slight swelling and bruising at  the injection site. Patients need to avoid strenuous activity and stay away from direct sun exposure and hot baths for 2-3 days. They can go back to their normal activities right after the procedure. The results should be noticeable within a few days. Some patients may require more sessions, usually 1-2 weeks apart, for the most effective results. Others may achieve permanent results after just one session.
