Asclera is an injectable used in sclerotherapy treatments to reduce the appearance of spider veins and small varicose veins. It is most commonly used to clear up veins in legs, and is usually done over the course of multiple treatments spread out over several weeks.

Treatments usually last between 30 minutes to an hour, and the majority of patients only experience mild discomfort during the duration of the treatment. Every patient is different, but most patients should wear compression socks after treatment to improve the final result.
