What makes some people have more viewable veins in hands than others?

Swollen hand veins.: Hand veins can swell for many reasons but the most common is certainly hereditary . Other factors would be level of hydration, aging, sun exposure and loss of elasticity and volume. Actually, I am amazed at the amount of women that i see with bulging hand veins. They can be easily treated with laser or sclerotherapy and usually a combination of both.

Loss of fat Cosmetic: Many factors are related to prominent veins of the hands...But the most common cause is loss of body fat. Most patients who present with prominent hand veins have lost weight or decreased weight. This leads to an aged appearance of the dorsum or back of the hands. The large vein appearance can be improved by laser ablation of the prominent veins, fat transfer and/or man-made filler injections.
