❌ Debunking the Myths
❌ “Red dots mean liver failure”
False — no direct link unless other symptoms present
❌ “They’re always a sign of cancer”
Dangerous myth — skin cancers have specific features (see below)
❌ “Only unclean people get them”
No — anyone can develop red dots regardless of hygiene
❌ “Scratching causes all red spots”
Not true — many appear without any irritation

When to See a Dermatologist
Don’t panic — but do act if you notice:

A spot that changes shape, color, or size
Bleeding, crusting, or non-healing sores
Rapid spread of dots with fever or illness
Pain, warmth, or swelling (possible infection)
Suspicious moles (use the ABCDE rule: Asymmetry, Border, Color, Diameter, Evolving)
A dermatologist can diagnose with a visual exam or biopsy if needed.
