What blood vessels are usually affected in cases of Acrocyanosis?

Acrocyanosis is a condition that causes the fingers, toes, and sometimes the ears and nose to turn blue or purple. It is most common in young women and is usually harmless. In cases of acrocyanosis, the small blood vessels in the affected areas are affected, specifically the arterioles and venules. These vessels are responsible for regulating blood flow to the extremities and may become constricted or dilated, leading to the bluish discoloration of the skin.
