Another frequent cause of small red dots on the skin is cherry angiomas.
These are small, round, bright red bumps.
They are caused by clusters of tiny blood vessels.
They are extremely common in adults over 40.
Cherry angiomas are not painful.
They do not itch.
They are not dangerous.
They tend to increase in number with age and are considered a normal part of the aging process. Many people develop several over time, often on the torso, arms, or shoulders.
While their bright color can be surprising, they are completely benign.
Heat Rash and Mild Irritation
Warm weather, physical activity, or layered clothing can sometimes lead to heat rash.
This often appears as small red dots or bumps.
It may come with mild itching or a prickly feeling.
Heat rash occurs when sweat becomes trapped in the skin.
For older adults, this can happen more easily due to changes in skin structure.
Keeping the skin cool, dry, and well-ventilated usually allows heat rash to resolve naturally.
Allergic Reactions and Sensitivities
Red dots can also result from mild allergic reactions.
These may be triggered by:
Soaps or detergents.
Lotions or fragrances.
Certain fabrics.
Environmental factors like pollen.
In these cases, the skin may feel itchy or irritated.
Once the irritant is removed, the spots often fade on their own.
Using gentle, fragrance-free products can help reduce these reactions.
