3. Spider Angiomas: Web-Like Red Marks
What They Look Like: A central red dot with tiny blood vessels radiating outward, resembling a spider web.
Causes:
- These are caused by dilated blood vessels near the skin’s surface. Common triggers include:
- Hormonal changes (e.g., pregnancy or liver disease).
- Sun exposure.
- High estrogen levels.
When to Worry: While spider angiomas are often benign, their presence in large numbers may indicate liver dysfunction or other systemic issues. If you notice multiple spider angiomas along with fatigue, jaundice, or abdominal swelling, consult a healthcare provider.
4. Rash or Allergic Reaction
What They Look Like: Raised, itchy, or blotchy red spots that may appear suddenly.
Causes:
- Allergies to food, medication, or environmental factors (e.g., pollen, chemicals).
- Contact dermatitis caused by irritants like soaps, detergents, or plants (e.g., poison ivy).
- Viral infections like measles, chickenpox, or rubella.
When to Worry: If the rash is accompanied by difficulty breathing, swelling of the face or throat, or widespread hives, seek emergency care, as this could indicate a severe allergic reaction (anaphylaxis).
5. Heat Rash or Prickly Heat
What They Look Like: Tiny red bumps or blisters, often appearing in areas prone to sweating (e.g., neck, armpits, groin).
Causes:
- Blocked sweat ducts due to hot, humid weather or tight clothing.
- Common in infants but can affect adults during heatwaves or intense physical activity.
When to Worry: Heat rash typically resolves on its own with cooling and proper hygiene. However, if the bumps become infected (pus-filled, swollen, or painful), see a doctor for treatment.
6. Keratosis Pilaris: “Chicken Skin” Bumps
What They Look Like: Small, rough red or flesh-colored bumps, often on the upper arms, thighs, or cheeks.
Causes:
- Buildup of keratin, a protein that clogs hair follicles.
- Often linked to dry skin, genetics, or hormonal changes.
When to Worry: Keratosis pilaris is harmless and doesn’t require medical intervention. Moisturizing regularly and using exfoliating products can improve its appearance.
