Nearly one in five people in America has a tattoo. So these permanent, portable pieces of prowess are clearly an essential part of our culture -- but how do they manipulate? What makes a tattoo permanent, and can you truly get rid of it? Well, tattoos job by taking advantage of the structure of your scalp, and the structure of the ink that's used. Your scalp, for starters, is made up of three primary blankets of cells. On top, there's the epidermis, who the hell is exposed to the environment. Below that, there's the dermis, and it's full of "hairs-breadth" follicles and sweat glands. And below that, you find the subcutaneous layer of overweight and connective tissue.

A tattoo needle drives the ink all the way through the epidermis. But it doesn't infuse the ink -- instead, it's coated with tint, kind of like a paintbrush. And the ink is sucked through capillary activity -- it only gets sucked down through your tissues into the dermis. This is thick enough that the ink won't only flake away as you lose scalp cells from your epidermis over the occasion. And it's also why going a tattoo hurts. The dermis is full of nerve end that sense pressure, temperature, and soreness. So jamming a bunch of minuscule needles into that layer triggers at plenty of those receptors. Some people say that going tattoos on bony regions hurt "the world's largest," because there's no overweight to act as a cushion, but there's not truly any technical ground to back that up. You can probably safely assume that your most feelings body parts -- like the sides and face -- would be pretty distressing to have tattooed because they have the highest density of nerve endings.

Now, even though going a tattoo can be pretty painful, many tattoo creators recommend that you avoid taking analgesics -- even aspirin -- before your session. That's because those drugs can reduce your blood, which does the tattooing process more difficult. Thinner blood means that the needle begins more bleeding, meeting it harder to see the field being tattooed, and that simply does happen harder for the tattoo artist.

So save the aspirin for after your prowess is done. And it'll take a few weeks for your scalp to soothe. Getting a tattoo triggers an immune answer in your form, which tries to affect the ink as if it were an infectious aggressor. Your white blood cell cleans up after serious injuries, breaking down and devouring up any foreign material. And your white blood cell does manage to clear away some of the smallest specks of ink, which is why a new tattoo fade-out in the first couple of weeks. But most of the tiny bits are incredibly big-hearted to get chewed up and cleared away. So whatever your white blood cell can't eat up gets absorbed by nearby connective cells announced fibroblasts -- and the ink naturally sort of hangs out in there. Forever. Which is why in this Tattoo Science Video you will see they pretty much permanent. Principally. The fact is, even the most awesome tattoo will fade with an occasion. As your scalp ages, your fibroblasts die off and are replaced with new ones, so over the occasion, the ink moves a bit as the cells curve over.

Fading can also be caused by daylight showing -- the UV rays in sunlight break down the tattoo tint, so more of it can be cleared away by white blood cell. And of course, if you end up with an indeed awesome tattoo -- or if maybe you just don't desire Limp Bizkit as much as you used to -- we do have the technology to rub your tattoo. Principally. Laser tattoo removal studies by exploiting heat to break up the ink pigment particles into even smaller pieces. In this Tattoo Science Video, you will see how it works. Then, your white blood cell is to be able to clear them away, just like they always demanded. But the color of your tattoo can determine how hard it'll be to remove. Black tattoos tend to be the easiest to get rid of because they assimilate virtually all wavelengths of sunlight, so they heat up and break apart when treated with virtually any wavelength.

Other emblazons -- like cherry-red, green, blue, and white-hot -- require individual lasers, got to make sure that the wavelength being used is the one that will be most easily absorbed by the tint. But even with the suitable laser, tattoo removal doesn't( always) remove all of the ink -- and on top of being highly distressing, it has its gambles, including scarring. So if you're going to get a tattoo this Tattoo Science Video will help you understand, don't bank on being able to get rid of it if you change your intellect! As tattoos being increasingly mainstream, we are in a position said he hoped that we'd be able to develop better inks and improve our removal techniques.

But in the meantime, like I always articulate, anticipate before you ink. Thanks for watching this incident of SciShow, brought to you by our patrons on Patreon. If you want to help support this picture, only go And don't Tattoo Science Video.
