I think they are called Purpura or she is taking the purple revolution too literally…
Purpura, also called blood spots or skin hemorrhages, refers to purple-colored spots that are most recognizable on the skin. The spots may also appear on organs or mucous membranes, including the membranes on the inside of the mouth.
Purpura occurs when small blood vessels burst, causing blood to pool under the skin. This can create purple spots on the skin that range in size from small dots to large patches. Purpura spots are generally benign, but may indicate a more serious medical condition, such as a blood clotting disorder.
Sometimes, low platelet levels can cause excessive bruising and bleeding. Platelets are the cells that help your blood clot. Low platelet levels may be inherited or genetic, but they may also be related to recent:
bone marrow transplants
cancer
chemotherapy
stem cell transplants
HIV infections
hormone replacement
