A permanently dilated vessel is a job for the clinic, since creams cannot retract it, so home care is all about prevention and comfort.
Compression hosiery genuinely reduces the pressure that drives new leg veins, and it is worth it for anyone who stands for a living. Elevating the legs at the end of the day does the same thing less effectively. Regular walking supports the calf muscle pump that returns blood upward.
