How Laser Tattoo Removal Works?
Updated: Sep 26, 2018
Before reading this article please note structure of tattoo ink (Tattoo for Body) is very different with cosmetic tattoo pigment (Known as permanent makeup/micropigmentation/microblading) Removal tattoo process is way more complicated than tattooing. It involves physics like thermodynamics, optics, even biology and chemistry are involved. We want to know how to remove a tattoo ink with a laser? If you get a little drop of tattoo ink and slide and place under a microscope you will see some metals. When we zoom in you can see these little bitty ink particles moving around, and then there's these much bigger chunks. During tattoo Multiple needles are puncturing your skin and dragging both big and little ink particles
down through the epidermis into the dermis. From the moment the tattoo is placed however your body's trying to get rid of it. Your body recognizes that it's foreign material as if you got a sliver under your skin. So your immune system is coming over looking at this stuff going "hey this doesn't belong here". White blood cells come in to remove the pigment.
Now the white blood cell is a very small little cell whereas the pigment granule is a relatively large structure if you looked at it under the microscope. That white blood cell actually comes over and tries to engulf the pigment granule, and because the white cell is so small and the pigment granule is so big, that munching away is a very difficult thing. It's like trying to take a bite out of an elephant. That's why tattoos are permanent? but that's also why they fade right, because part of the ink is drug away but part of the ink stays. If you look at a freshly placed tattoo, it looks very sharp, it has very clean edges, very clear colors, very crisp. If you look at a tattoo for years ago, that tattoo's starting
to look faded. Because what's happening is that pigment is being eaten by those white blood cells and carried through the lymphatics of the skin, because it's headed for your liver, if you have the right type of laser removal, when you hit it with a pulse of light, that pigment granule will shatter. As you shatter the pigment granules you're making them smaller and more edible. So you're accelerating the speed with which the white blood cells can remove the pigment. the white blood cells are trying to take it to the liver. That's the way out. The laser gonna zap the ink and then the white blood cells are gonna go grab the broken up ink particles and take it to the liver. Through the lymphatic channels of the skin, into the larger lymph channels deeper down, and ultimately through the liver for cleaning up and excretion. It might takes a few removal treatments before the body can fully process the ink.
