Noticing red dots on your skin can be alarming, but many are harmless. Common causes include cherry angiomas (benign blood vessel growths), heat rash, allergic reactions, or folliculitis from irritation or shaving. Others, like petechiae, cellulitis, or vasculitis, may signal infections or more serious conditions—especially if they appear suddenly, spread, or come with fever or fatigue. If red spots are painful, persistent, or accompanied by other symptoms, it’s best to consult a healthcare provider. Your skin can reflect deeper health issues, so paying attention to changes is always wise.
