Why Are There Small Red Dots on the Skin?
Disease description:
I am a 28-year-old female. Recently, I noticed some small red spots appearing on my arms and legs. They are neither painful nor itchy, but they look somewhat alarming. I hadn't noticed these red spots before and don't know what caused them. May I ask why these small red spots appear on the skin?

There are many reasons for the appearance of small red spots on the skin, including capillary dilation, allergic reactions, subcutaneous bleeding, hormonal changes, or other skin diseases. Capillary dilation is usually caused by skin irritation or temperature changes, leading to the expansion of tiny blood vessels on the skin's surface, forming small red spots. Allergic reactions may be triggered by foods, medications, or contact substances, resulting in red spots on the skin. Subcutaneous bleeding may be caused by minor trauma or abnormal blood clotting function. Hormonal changes, such as during pregnancy or the menstrual cycle, can also lead to small red spots on the skin. Other skin conditions, such as eczema or urticaria, may also present as small red spots.
It is recommended that when small red spots appear on the skin, one should first observe whether there are other accompanying symptoms, such as itching, pain, or fever. If there are only a few red spots and no other discomfort, it is advisable to keep the skin clean and avoid using irritating skincare products. If the red spots continue to increase in number or are accompanied by other symptoms, prompt medical attention is advised for professional diagnosis and treatment. In daily life, protecting the skin from sun exposure, avoiding skin irritation, and maintaining healthy lifestyle habits can help reduce the occurrence of skin problems.
