Your Tattoo is INSIDE Your Immune System. Literally
Kurzgesagt – In a Nutshell・2 minutes read
The skin sheds millions of dead cells constantly, including those where tattoos are embedded, leading to the immune system's involvement in response to ink particles and leading to the eventual fading and spreading of tattoos in the body. Macrophages play a crucial role in defending against tattoo ink, trapping and sometimes releasing particles, showcasing the immune system's protective function and the complexities of tattoo permanence.
Insights
- Dead skin cells shed at a rapid rate, with around 200,000,000 cells being replaced every hour, showcasing the constant renewal process of the skin.
- Macrophages play a crucial role in the immune response to tattoos, attempting to neutralize ink particles, highlighting their protective function and the complex interplay between the immune system and tattoo permanence.

Recent questions
How does the immune system react to tattoos?
The immune system responds to tattoos by sending Macrophages to defend against bacteria and toxic ink particles.
How do tattoos fade over time?
Tattoos fade over time as Macrophages age and die, allowing some ink to escape and spread throughout the body via fluids.
What is the role of Macrophages in tattoo permanence?
Macrophages play a crucial role in tattoo permanence by attempting to engulf and neutralize ink particles, trapping them within themselves to prevent spreading.
How are tattoos removed with lasers?
Tattoos are removed with lasers by breaking down ink particles, potentially harming Macrophages, which continually work to retain the ink.
Why do tattoos spread throughout the body over time?
Tattoos spread throughout the body over time as ink particles escape when Macrophages age and die, allowing them to travel via fluids.
