YSX Facial Vein Repair is a highly effective treatment for facial thread veins or 'broken' veins - fine visible veins which appear near the surface of the skin. These veins are most commonly visible on the cheeks and nose, and tend to become larger and more intensive over time appearing in clusters with a red or purplish appearance. Exposure to the sun's ultra voilet rays, wind or extreme temperatures, steroid creams, hormonal changes during pregnancy and radiotherapy have all been recognised as causes of facial thread veins. This delicate cream visibly reduces the appearance of facial thread veins by gently thickening and strengthening the skin.
