Noticed Purple Lines on Your Legs? They May Be Telling You Something

2. Spider veins

If the veins look more like tiny branches or a spider web rather than large, bulging cords, they could be spider veins.

Spider veins are small blood vessels close to the surface of the skin. They can appear red, blue or purple and are particularly common on the legs. In most cases, they're harmless and mainly a cosmetic concern.

However, spider veins can sometimes occur alongside problems with blood flow in the veins, so persistent or changing symptoms are worth discussing with a healthcare professional.

3. Getting older

Age can also play a role.

As we get older, the walls and valves of our veins can gradually lose some of their elasticity and efficiency. This can make veins more likely to become enlarged and visible beneath the skin.

That's one reason visible veins may become more noticeable over the years.
