Small red dots like pinpoints on the body are usually symptoms of skin breakage, spider nevus and cherry-like hemangioma. 1. Small red dots caused by skin breakage are generally caused by extrusion or bumping. After trauma, blood seeps out from broken capillaries under the skin, but the blood cannot flow out from the epidermal stratum corneum intact to form blood spots. In this case, the blood will be absorbed after a few days. 2. The reason for the formation of spider nevus is not completely clear at present, but it is mainly related to capillary malformation caused by high estrogen level. When a woman is pregnant, it will lead to high estrogen level, and the poor inactivation of estrogen by the liver in severe liver disease will also lead to estrogen elevation. 3. Cherry-like hemangioma is a kind of benign skin proliferation, the etiology is unknown, and skin aging, blood vessel elasticity decreased related to female patients than male. Sun exposure, vitamin E deficiency, lack of sleep and other triggers are likely to aggravate hemangioma. There may be other reasons for the pinpoint red dots on the body, and it is recommended to go to the hospital for a clear diagnosis and symptomatic treatment.
