Noticing red dots on your skin can be alarming, but they’re often harmless. Still, some types may signal underlying health issues. Here’s a simplified breakdown of common causes:

These tiny red or purple spots result from bleeding under the skin, often after coughing, vomiting, or taking certain medications. While usually harmless, widespread petechiae can indicate conditions like blood clotting issues or infections. “If you notice widespread petechiae, it’s best to consult a healthcare provider.”

Cherry angiomas are small, bright red bumps caused by overgrown blood vessels—common with age and usually harmless. Heat rash (miliaria) causes itchy red bumps from blocked sweat glands and clears with cooling.

Red, itchy patches or hives often signal an allergic reaction. Avoiding triggers and using antihistamines can help. Folliculitis causes red bumps around hair follicles due to infection and may need antibiotics.

Cellulitis is a painful bacterial infection needing urgent care. Impetigo causes oozing sores, especially in kids. Vasculitis involves inflamed blood vessels. Hemangiomas are raised red birthmarks, usually harmless but sometimes treated.

Seek help if red dots come with fever, swelling, fatigue, or rapid spread. “Staying aware of your body’s signals is key to your health.”
