Small red dots on the skin can be a cause for concern, especially if they are persistent or accompanied by other symptoms. While some red spots may be harmless, others could indicate an underlying health issue that requires medical attention. Here are 10 possible causes of small red dots on your skin:
- Heat rash: Small red dots that appear on the skin after exposure to hot and humid conditions. They are caused by blocked sweat ducts and usually clear up on their own.
- Allergic reaction: Red spots can be a sign of an allergic reaction to certain foods, medications, or skincare products. Seek medical advice if you suspect an allergy.
- Psoriasis: This chronic skin condition can cause red, scaly patches on the skin, including small red dots. Treatment options are available to manage symptoms.
- Eczema: Another common skin condition that can cause red, itchy patches on the skin. Eczema flare-ups may result in small red dots.
- Petechiae: Tiny red or purple spots that appear on the skin due to broken capillaries. They can be a sign of a serious medical condition and should be evaluated by a healthcare professional.
- Measles: A viral infection that can cause a red, blotchy rash on the skin, including small red dots. Vaccination can prevent measles infection.
- Scarlet fever: A bacterial infection that can cause a red rash with small red dots on the skin. Antibiotics are usually prescribed to treat scarlet fever.
