If you notice small red dots on your skin, they can have many causes. Some are harmless, while others may need medical attention.
What they are
Red dots may include cherry angiomas, petechiae, or rashes. They can appear as tiny flat or raised spots and may show up alone or in clusters.
Common causes
Allergic reactions
Insect bites
Heat rash
Skin infections like folliculitis or impetigo
Minor injury or irritation
Less common causes
Blood or autoimmune disorders
Medication side effects
Nutritional deficiencies
What to watch for
Red dots may itch, feel tender, or change over time. Sudden spreading, color changes, or new symptoms should not be ignored.
When to see a doctor
Seek medical advice if red dots persist, spread quickly, or appear with fever, pain, fatigue, bruising, or bleeding.
Treatment and prevention
Mild cases may improve with basic care like cold compresses or antihistamines. Other causes may require medical treatment. Protecting your skin, avoiding allergens, using sunscreen, and maintaining a healthy diet can help prevent recurrence.
Bottom line
Most red dots are harmless, especially cherry angiomas, which are common with age. Still, unexplained or worsening symptoms should always be checked by a healthcare professional.
