What causes red dots on lower legs?

Red dots on the lower legs can be caused by various factors, including allergic reactions, insect bites, or skin conditions like eczema or psoriasis. Other potential causes include petechiae, which are tiny bruises resulting from bleeding under the skin, or foliculitis, an inflammation of hair follicles. In some cases, conditions like vasculitis or infections may also lead to red spots. If the dots persist or are accompanied by other symptoms, it’s advisable to consult a healthcare professional for a proper diagnosis.
