Many people know that while facial surgery helps you look younger, hands often reveal your true age. As people age, they often lose fat tissue in their hands as well as skin elasticity, making the hand veins more prominent and distinguishable. This process is accelerated by sun-induced damage, which results in wrinkled, discolored skin, and prominent superficial veins of the hand. These veins get larger and more noticeable over time.
The anatomy of the arm and hand is very much like that of the leg and foot. There are many veins which are able to return blood to the heart. Superficial hand veins (the surface veins we can see under the skin) are not essential, since there is a rich network of deep veins that is more than adequate to drain the hand. When treating hand and arm veins, we are always careful to evaluate each patient for adequate veins in the forearm for future IV medications.
