"The gold standard" for eliminating smaller varicose veins and superficial telangiectasias (spider veins). It involves an injection of a solution (generally a salt solution) directly into the vein. The solution irritates the lining of the blood vessel, causing your body to reabsorb it and gradually fade.
Causes for varicose veins and spider veins can be aggravated by pregnancy, birth control pills, hormonal therapy, prolonged periods of sitting or standing, obesity, aging of the tissues, or trauma. Leg veins are progressive, meaning that new ones will appear overtime.
Multiple sessions are usually required, approximately 5-6 weeks apart.
