Tiny red spots on skin may signify the occurrence of several underlying skin conditions. Some disorders disappear on their own without treatment, while others need medical therapy.

Some of the different conditions which cause tiny red spots on skin are listed below:
- Acne: It typically affects teens and fades away when one reaches 25 years of age. It is caused due to bacterial infection and can result in whitish or tiny red spots on skin, a reddish pimple, or a blackhead.
- Allergic reactions: Tiny red spots on skin may develop as an allergic reaction to certain foods and drugs, or to environmental allergens like pollen, duct etc. They may also form due to mosquito and ant bites, or wasp and bee stings. Sun allergies like actinic prurigo, polymorphous light eruption, and solar urticarial may also cause the skin anomalies after prolonged contact with the sun. Most spots caused due to allergic reactions are itchy.
- Boils: They appear as tiny red spots on skin or as pus-filled, yellow-pinkish bumps and occur throughout the body.
- Cherry angioma:It is identified by development of dome-shaped, purplish or reddish, non-itchy bumps. It occurs across age groups.
- Heat rash: It is a common skin condition caused due to trapping of sweat below the skin after prolonged sun exposure.
- Birthmarks: They can be congenital or appear after birth. The accompanying tiny red spots on skin are related to minor blood vessels anomalies.

- Petechiae: It is caused due to bleeding of capillaries occurring below the skin. The resultant tiny red spots on skin do not lose color on application of pressure.
- Rosacea: It has no known causes, but may have genetic links. Individuals with fair skin are usually affected. It causes a flushed facial appearance along with formation of pimple-like, red clusters on skin.
- Pyogenic granulomas: It generally affects children and is caused due to blood vessels buildup. It results in formation of tiny red spots on skin which may also be bluish, brownish, or purplish. The exact cause of blood capillaries accumulation is not known.
