If you’ve noticed small red dots on your skin, you’re not alone — and while many are harmless, others can signal underlying health concerns.
What Are These Red Dots?
Red dots on the skin can range from cherry angiomas (harmless clusters of blood vessels) to petechiae, which may indicate bleeding under the skin. These spots can be flat or slightly raised, and vary in size and color from bright red to purple or brown.
Common Causes
-
Cherry Angiomas – Small, bright red bumps, common with age.
-
Heat Rash – Caused by trapped sweat, leading to itchy red spots.
-
Allergic Reactions – Triggered by food, medication, or insect bites.
-
Folliculitis – Infected hair follicles, often red and pus-filled.
More Serious Causes
-
Vasculitis – Inflammation of blood vessels; may be linked to autoimmune conditions.
-
Cellulitis – Bacterial skin infection requiring antibiotics.
-
Impetigo – Contagious infection, mostly in children, with oozing red sores.
When to Seek Medical Help
See a doctor if:
-
Red dots rapidly increase or change.
-
They’re accompanied by fever, fatigue, or pain.
-
You experience unexplained bruising or bleeding.
