Red dots on the skin can have various causes, some resolving on their own while others require treatment. Common causes include allergic reactions, acne marks, birthmarks, heat rash, insect bites, autoimmune conditions, and infections. Specific conditions include petechiae (tiny red dots from damaged capillaries), cherry angiomas (harmless red bumps from blood vessel overgrowth),

folliculitis (infected hair follicles), cellulitis (bacterial skin infection), and vasculitis (inflammation of blood vessels).Home remedies include applying aloe vera gel, massaging with coconut oil, and drinking dandelion root tea for detoxification. However, consulting a doctor is recommended, especially if the spots change in appearance. A healthy diet with fruits, vegetables, and good fats can also support skin health.
