What causes blue veins to be prominently visible on your hand or arms? Why is it more with some people than others?
I have a question about veins. Why are some people's blue veins more prominently visible on their hands or arms than others?
The visibility of veins is affected by a number of factors including the thickness of the skin, the amount of subcutaneous fat, and the level of hydration. Usually, people with lighter skin color have more prominent veins.
