What is Livedo Reticularis? Causes and Symptoms Explained

Livedo reticularis is a skin condition characterized by a mottled or net-like pattern of reddish or purplish discoloration on the skin, often seen on the legs, arms, or trunk. The pattern is caused by the constriction of small blood vessels (capillaries) in the skin, leading to a reduction in blood flow and the pooling of deoxygenated blood. This results in the characteristic appearance of a lace-like or mesh-like pattern.
