Most people hardly pause when they notice odd color changes on their skin. A light bluish tint here, a patch of redness there — easy things to brush off. But sometimes the skin speaks long before anything else in the body does. And one of the clearest examples of that is a condition called livedo reticularis.
At first glance, livedo reticularis looks almost decorative — a delicate, lace-like pattern running across the skin in shades of purple, blue, or reddish violet. It often appears on the thighs, calves, arms, or torso. For many, it comes out after stepping into the cold and disappears as soon as the body warms up.
