11 Reasons Why You Have Red Dots On Your Skin

1. Cherry Angiomas

These are small, bright red spots made up of blood vessels. Totally harmless and very common, especially as you age.

2. Petechiae

Tiny red or purple dots caused by bleeding under the skin. These don’t fade when pressed and can indicate something more serious like an infection or a clotting issue.

3. Heat Rash

Also known as “prickly heat,” it shows up as small red bumps due to blocked sweat glands—common in hot or humid conditions.
