Why Are Veins Visible at All?
Before understanding why they look more noticeable, it helps to know what veins do. Veins are responsible for carrying blood back to the heart. Unlike arteries, they sit closer to the surface of the skin, especially on the hands.
The skin on the hands is thin, flexible, and exposed to sunlight and movement all day. Because of this:
-
The skin becomes thinner with age
-
Fat under the skin decreases
-
Veins naturally appear more visible
So visible veins on the hands are often simply a combination of anatomy and aging, not a sign of illness.
