Red dots on the skin can result from various causes—some harmless, others needing medical attention.

• Petechiae & Purpura: Tiny red spots from broken capillaries. Often harmless but can signal conditions like platelet disorders.
• Cherry Angiomas: Bright red bumps from blood vessel overgrowth. Common with age and usually harmless.
• Heat Rash: Caused by trapped sweat, leading to itchy red dots—especially in hot, humid conditions.
• Allergic Reactions: Red, itchy rashes triggered by food, medications, or insect bites.
• Folliculitis: Infected hair follicles, resulting in red, pus-filled bumps.
• Cellulitis: A painful, warm skin infection that needs antibiotics.
• Impetigo: Contagious red sores common in children that ooze and form a crust.
• Vasculitis: Inflamed blood vessels causing red spots, sometimes linked to autoimmune issues.
• Hemangiomas: Birthmarks from blood vessel overgrowth—usually harmless.

When to See a Doctor:
Seek medical help if red dots are painful, spreading quickly, or accompanied by fever, fatigue, or dizziness.
