Did You Know!
Your Skin Has Its Own Immune System
Most people know the skin protects against germs, but it also has specialized immune cells called Langerhans cells that constantly “patrol” for invaders.
- These cells detect harmful bacteria and viruses and alert your immune system, acting like tiny bodyguards.
- Fun fact: This is why small cuts or scrapes often turn red quickly — it’s your skin’s immune response kicking in before the rest of your body even reacts.
