Tattoo removal is a complex process that involves more than simply erasing unwanted body art. Laser-based treatments are the most common method, using intense heat—sometimes reaching up to 300°C (572°F)—to break down the pigment in the skin. This high-energy light effectively blasts the ink particles into smaller fragments.
Once the pigment is shattered, the body’s immune system steps in. White blood cells absorb the tiny ink particles and transport them via the lymphatic system. These particles are then filtered through the liver and kidneys before being expelled as waste, primarily through urination. Additionally, some ink is released as the skin heals post-treatment.
This scientific explanation was provided in response to a question from Tony Holder of Hereford, illustrating the fascinating biological processes behind tattoo removal. It highlights how our bodies play a crucial role in eliminating foreign substances, aided by advanced medical technology.
