What causes red dots on the bags under someone's eyes?

Someone who is experiencing red dots on the bags under their eyes may be encountering bleeding into the skin, as noted by MedlinePlus. This occurs when blood vessels beneath the skin break.

There are several causes of bleeding into the skin:

• Trauma to the area
• Allergic reactions
• Autoimmune diseases
• A viral illness preventing the blood from clotting
• Thrombocytopenia
• Taking anti-platelet medications or anticoagulants
• Aging skin
• Leukemia

People who experience sudden bleeding under the skin should speak to a health care provider to determine the cause. The clinician dealing with the case is likely to ask questions about recent injuries, medications, illnesses and family history of diseases. They may also perform tests, such as coagulation tests and white blood cell counts.
