Why do the veins in the hands become visible with age?

The layer of fat beneath the skin thins with age, which is why older individuals often have prominent veins not only on their hands, but also on their legs and other parts of the body. In some people, veins may naturally be located close to the skin's surface.

Furthermore, hands age as quickly as the neck and face. Indeed, they are often exposed to the elements (sun, wind, cold, etc.), friction, infectious germs, and pollution. These constant aggressions weaken them and reduce the secretion of the protective hydrolipidic film. Cold weather, in particular, decreases the secretion of the sebaceous glands.

Typically, the skin begins to thin out starting from the age of forty. Additionally, the first spots start to appear. After fifty, veins and tendons become increasingly visible. Moreover, the muscles diminish, the skin loses its firmness and wrinkles. The underlying bones become prominent.
