The skin can often reflect what’s happening inside the body. Livedo reticularis (LR) illustrates this connection. It is a vascular condition that manifests as a purplish, net-like or lace-like discoloration. Although it may seem worrisome, livedo reticularis is not always a sign of a serious underlying disease. However, in some cases, it can be associated with systemic conditions requiring medical attention.

What is Livedo Reticularis?
Livedo reticularis is characterized by a mottled, web-like, reddish-blue or purple discoloration that typically appears on the legs, arms, or trunk. This condition occurs when blood flow in the small subcutaneous blood vessels is interrupted, slowed, or irregular, causing a pooling of deoxygenated blood. This discoloration typically becomes more noticeable in cold weather and may fade when the skin warms.
