Telangiectasia (Spider Veins)

Telangiectasia, often called spider veins, is a widening of tiny blood vessels near the skin's surface that shows up as thin red, purple, or blue lines, and it is usually a cosmetic concern. People most often look at horse chestnut extract and hesperidin/diosmin, which are rated as having moderate evidence, though little research on spider veins specifically has been reviewed here so far. Vitamin C, grape seed extract, bilberry, gotu kola, and rutin have even less behind them, so the evidence there is limited.
