Your Tattoo is INSIDE Your Immune System. Literally

Summary by Krater

This video explores how tattoos interact with the human immune system, explaining the structure of the skin, the immune response to tattoo ink particles, and why tattoos are permanent despite white blood cells trying to remove them.

From the video

Answers: What happens to a tattoo inside your skin?

• skin layers and biology
• immune system response to tattoo ink
• macrophages and phagocytosis
• tattoo removal process and laser treatment

What it concludes

• Your skin is made mostly of dead cells functioning as a conveyor belt of death to protect you.
• Tattoo ink particles are too large for macrophages to dissolve, so they swallow and trap them in place.
• Laser treatment heats up tattoo ink particles, breaking them into smaller chunks that are carried away by fluids and macrophages.
