Most people think that tattoos work by "pushing" or injecting ink under a layer of skin, but that's actually not the case...

So there’s actually a lot more you could’ve gone into in this video, I’m a tattoo artist out of Las Vegas but I’m also kind of a big Science nerd so I’ve done a lot of research into how tattoos actually work, the hole injection theory isn’t the only misconception about tattoos. Most people don’t fully realize how crazy a healed tattoo is and how it works, most people think the skin heals around the ink and traps it ‘dying’ the skin but what really keeping the ink in your skin is your white blood cells. Considering ink is a foreign substance entering the body it only makes sense that your white blood cells wouldn’t take it too kindly, But white blood cells can’t break down tattoo ink so instead they trap it and quarantine themselves staying in the same place till they eventually die. This not only is why your tattoos stay where they are but it’s also part of the reason tattoos fade and smudge over time because when each white blood cell quarantining dies another white blood cell will swoop in and take its place but not it’s exact spot and sometimes it doesn’t catch all the ink. This also helps explain laser tattoo removal, what the laser is actually doing is burning the white blood cells to get rid of the ink, But the laser can’t fully get rid of the ink so some of it stays and the rest flows down your bloodstream to be deposited in your liver. That’s also why laser tattoo removal takes so many sessions. Hope this wasn’t annoying and maybe it was interesting to someone out there lol
whoa i didn't know that about the white blood cells! That is so cool. I def hope Kyle sees this because your explanation was really great!
The minute spent reading this comment was at least 15 times more useful than this whole video
Thank you
I did not know this and had not even thought about it to that extent. This is pretty awesome info
As someone with 80% of his skin tattooed I found this pretty interesting. Thanks for taking your time to write all that down. Much appreciated.
That was actually super interesting. Thanks for taking the time to share!
I did my fist tattoo myself a night when I was 12 years old while reading Henri Charrière’s “Papillon” in which Henri makes a tattoo with a razor blade and ink. My 12-year-old mind with no sense of consequence said “I wonder if it works, I have to try this!”. Well, it did. So at the age of 12 I had a prison tattoo of what was supposed to be a heart, but in reality looked like a liver with cirrhosis. My middle school friends were in awe, my middle class parents, not so much.
The Facility: *has extremely hi-tech equipment, spacecraft and supercomputers*
also The Facility: *requires a Kevin to hold up a paper towel*
And a stick
jokes on you Kevin is a Synth Kyle is the only "human" in the facility
Kevin is the most high tech creation there.
HEY, if Kevin isn’t holding up paper towels and other such menial tasks, they would be merely lumps of useless flesh. I mean, you don’t want a bunch of Kevins running around the surface world now do you? The cost to dispose of them All is too great, so, they serve a purpose, no matter how small.
@@GuitarsRockForever His parents fucking thought so.
Gave me chills when I saw the "pale blue dot" tattoo.
My wife asked me if I wanted to participate in our counties "painted rock" thing, where you hide painted rocks.
The first thing that came to mind, was "pale blue dot." I wanted to share a incredible speech to others who may have never encountered it.
Bravo sir, great decision.
The most impressive thing about this to me is Kyle has a tax deductible tattoo now
Had the exact same thought
Good, I'm not the only one that thought that.
Gottem lmao
Wait what does that mean? English is not my main language and honestly there are still quite some concepts i dont know.
Not sure about the US laws but... If a tattoo artist inks himself, wouldn't that be also tax deductible, since he his making it to advertise his buisness?
tried to get the pulsar map under my skin a couple of times, everytime the artists said the lines are to close to each other for a small tattoo, they will wash out after some time and fuse together.
Now I am seeing yours and might give it another go.
It looks great, very well done.
The bigger the tattoo the easier the artist can make precise lines that will stay where they're supposed to for years. You might need to get a bigger tattoo than what you imagined at first
As a tattoo artist of 15+ years, I can definitely say this is all true (I had to learn this during my 5 year apprenticeship.) However, just to add some extra information, the tattoo machine will usually run at roughly 3000-5000 "punctures," for a lack of terminology, per minute. We also go roughly 1/16th of an inch into the skin as to not create severe heavy scarring. As for the capillary effects, it actually does continue even after you're healed. This is why most artists will recommend not going below certain sizes on tattoos, as the ink does "bleed" into other skin cells over time. Think of it as a sharpie marker on a paper towel, just much slower. If a tattoo is done too small, the design can actually "bleed" into itself within anywhere from a few months to a year, depending upon the size of the tattoo. Even when a tattoo is done at a decent legible size though, ink does still spread a small amount over time, causing touch ups to be needed. Actually, the capillary effect, quality of skin care, and UV exposure can effect the way your ink heals, and how long it lasts. I know I'll usually recommend Dove or Ivory unscented soap and then unscented lotion after it drys, but always follow your artists instructions as they know best how their ink heals. That said, lotion and sunscreen will prolong the life of the tattoo and make it to where you won't need touch ups within a couple years.
As someone with sensitive skin I found the only sunscreen I could use on mine were sunscreens that didn't cause my face to break out. My ink saw a lot of Olay UV Daily Protectant over the years (they all need to be redone now, but the youngest is more than old enough to buy alcohol). The ink keeps moving over time, too - the longer you've had it (especially noticeable with black ink) the more ink a pathologist will find in your lymph nodes at your autopsy.
Thanks for the extra details from a pro!
I mean yes, but also tattooing has come a long way in the last 15 years and micro tattoos are a lot more doable nowadays with techology and skill changing and improving
Interestingly of all my tattoos my Irezumi show the least impact of time. Very little bleeding or fading. But you definitely get a better view of the capillary action at work.
I honestly never thought about the science behind tattoos. I’m not comfortable enough yet to get one, but I’m always hungry for cool science information and this was super educational? Thanks so much 1990tattoo!
@@patricia1333 it took me 42 years before I got my first one. I needed my first one to have meaning behind it, because I didn't want to get something random slapped on my body permanently. My first was a memorial tribute to my dad. It was Goofy as a firefighter (my dad loved goofy, and he was a retired firefighter) up on my right shoulder. I got my second one a year later. It's Thing 1 & Thing 2 from Cat in the Hat. I refer to my two boys as Thing 1 & 2 all the time, so it was more than fitting.
The only advice I can offer you, is to plan out what you want, where you want it, and go talk to the artist that you're interested in working with. I've known my artist for 25 years now, we went to high school together, and he works at one of the best shops in my area. He's done my two (planning another already), my mom's two, and my wife's one.
Everything 1990tattoo said is spot on, always make sure you follow the artists specific instructions of caring for your new tattoo!
"A pale blue dot" is one of the most beautiful text ever written.
Excellent choice for a tatto.
Kyle got a tattoo in this episode but didn't have a tattoo at the end which must mean one of the Kyle clones has escaped while kyle got a tattoo in an attempt to over throw the current Kyle Mountain, making himself the superior Kyle and soon will take over the facility dooming the remaining Kyle clones to eat ketchup flavored ice cream for all eternity.
I guess we will find out which Kyle will reign supreme at the next live, will it be tattoo Kyle or nontattooed Kyle?
I hope it's tattooed Kyle, he has a really cool tattoo.
Plot twist: The facility didn't like Kyle getting a tattoo that wasn't for nefarious purposes and used high tech lasers to remove it in his sleep.
@@fcasias7 Specifically the lasers on top of their sharks
I'm in the "escaped Kyle is one of the clones" and Supreme Kyle is the one doing videos because of the Supreme Intelligence without needing an AI to supplement him. Unless.. He does.
I wonder, if you clone somebody that has a tattoo, will the clone have a tattoo as well?
@@stonedwookiee278 probably not the tattoo is not biological
This was really cool, I had only ever thought about the biology of why the ink stays, not the mechanism by which it got there in the first place. Also, excellent choice of tattoo, it's a fantastic idea and looks great!
P.S. I want to do experiments in the jelly lab, that looks fun, hehe
After the "how does it get in there"? Episode, you should do the "how does it stay there Episode"?
More immunology than physics, but fascinating.
“Some of you feel called out, and I don’t care.” - I don’t have tattoos but that’s damn funny. 🤣💯
This needs a link to SmarterEveryDay’s video on tattoos. In slow motion you can see the capillary action almost appearing to suck in the ink and it even grips the head of the tattoo needles.
The first time I heard that Carl Sagan speech and saw that photo of Earth, I cried. Great tattoo.
Same
"...into which ink can seep." Actually, Kyle, since capillary action is the method of getting the ink "all up in it" as you mentioned earlier in the video, I believe the correct word would have been 'wick' instead of 'seep'.
Wick is typically used in the context of a "thing" (candle wick, paper towel, etc.) using capillary action to move a liquid. Seep is typically used in the context of a liquid filling a void. You make a good argument, given that wicking explicitly mentions capillary action, but I believe Seeping is still perfectly valid.
@@YamiOni This commented just viscerally reminded me of something I read about once - a medieval torture technique where the would use a similar process to wick candle wax under the skin and effectively turn people into candles. Evidently inquisitors didn't fuck around...
Hey Kyle, glad you made it through your first tattoo! It's amazing to see the science behind the procedure.
It's not just capillary action. The ink also gets dragged in by the needle.
Edit to add more details, the pigments in tattoo ink are solid and this not subject to capillary action the same way liquid is. The larger particles are stuck in the skin and can't be removed by your body. When you get a tattoo removed by a laser, it's being broken up into smaller particles the body can remove. These particles are getting dragged into the skin by the needle.
you could also argue that those particles get dragged around by the fluid from adhesion to the fluid, As they do remain dispersed amongst the ink and does not settle separately.
Kyle never said it was the only action allowing the tattoo just the primary action, all of what you said is true aswell , most things in the world don't just have one action causing them its alot of different things that add up to one whole
Yeah I don't think I ever questioned how the ink got down there. My question was always, if we're constantly regrowing skin and foreign objects tend to work their way out, how does the dyed skin stay dyed and not completely faded over time. I know tattoos get lighter and green/blue. Is that it working it's way out? Sun breaking down the pigment? If we lived longer, would tattoos eventually disappear?
@@BensBrickDesigns So the pigment is below the layer that is constantly regenerating. That keeps it from going anywhere. Sun damage is the main cause of discoloration, but so is pigment breakdown. The particles migrate over time through the skin, though very slowly, and that's why old tats get fuzzy.
@@KalijahAnderson So what is the property of the ink/pigment that keeps it regenerating? Does it live in like a pigment layer of skin that's beneath the layer of skin that's constantly regenerated and eventually sloughs off? Genuinely curious.
Capillary Action and Osmosis is one reason why you're not supposed to soak a tattoo until it's fully healed. The water can get in and dilute the ink, making the tat look bad
Additionally, the simplest tattoo ink is carbon particles (in the form of soot) and a carrier like purified water or alcohol. The carrier is carried away by the body, leaving a tube of particles of carbon in your skin. The top layer eventually heals, leaving a "bubble" of carbon under your skin. The particles are too big for the body to carry away, so they stick around pretty much forever. Over time they do break down a bit, especially with UV exposure, and thats why tats fade! Laser tattoo removal is basically a concentrated form of that process, breaking particles down small enough for the body to carry away
Congrats on your first tattoo, be sure to follow the artist's instructions for care, they know best.
As someone with tattoos and curiosity I pestered my artist with questions. This is a fun video so thanks!
Ever since Kyle hit 1 million subs it's gone to his... production budget.
I was kind of surprised - the only thing I've ever seriously considered getting a tattoo of was either this specific quote or "we are a way for the cosmos to know itself"...
Got my first piece when I was 19, I got a huge raven on a dreamcatcher and I don't regret it not even a little, I love all my tattoos and they are all symbolic to me. They really don't hurt much either besides certain areas, otherwise you could end up falling asleep in the session like me lol. Also I would recommend getting large pieces, but that's just me :)
I've got 5 smaller pieces on my forearm at the moment. Got the first when I was 22 or so. Plan to eventually be covered, lol. Love them all, and no regrets except wishing my first had been in color like the rest.
4and a half hours for that !? Holy cow, was it his first tatoo ? My very well reputed local Tatoo artist did my half sleeve, reaper background woid , moon and crows, a half sleeve in 2hours... (I jnow she does work fast comparatively to normal Tatoo artist i was expecting 4hours for mine) but what kyle got she wouldve done it in... 30mins max. Im speechless...
I was thinking the same thing!
I've had a total of 7 artist do work on me throughout my life and none of them took that long... I have a 4in by 3in (ish) piece on my leg that was done by a newbie but he still only took 1 and a half hours for line and fill!
The Main artist I go to has done a lot on me and we're currently finishing up my full sleeve-a session has never been over 2 hours even on pieces with lots of precise lines followed by some fill...
(my guys been doing his work for 20 years though so... Experience maybe?)
It might very well not be the artist's fault, there are a lot of factors at play when someone is getting a tattoo. This artist could be relatively new or he could have wanted to be careful. Or maybe they were just setting up shots for like 60% of that time heck if I know. Point is, with experience comes speed, and I can't imagine that being filmed at work would help my nerves if that were me
In the 4th grade I accidentally gave myself a graphite tattoo in my hand trying to throw my pencil into the drop ceiling at school. It is still there to this day, over 20 years later
Love that you added the pulsar lines from the Voyager Golden Record too!
I made a diagram on this a few months ago actually. I'm a tattoo artist and was feeling inspired by watching your videos. I'll DM it to you!
I'm a bit confused with the jelly test. Since you put the color on top of the jelly, gravity also made it go down the little holes which is the opposite of the effect you wanted show, since the capillary force should work against gravity, not with it. Wouldn't it be better to pick it up, flip it and put the color on the surface from below?
It's also not just capillary action. The groupings of the small tattoo needles, and why most needle bars do not have just a single needle, are created specifically to help push (not inject) the ink into the hole that was just made by the machine. We have capillaries pores and microscopic holes in our skin across every inch of it and if it was all only capillary action the tattoo would not be as crisp and specific bc the ink would not only be sucked up by the holes the machine made but also by other micro holes and pores. I have heard of some artists using a shading technique that involves using an empty needle and then spearing the ink across the holes the empty needle made on the skin but that's the closest to capillary action being the reason for ink going into the skin that I can find.
It is so weird seeing a tattoo artist that doesn't have any visible tattoos
I have met quite a few without any art on them. There's many reasons these guys and gals don't get them. Some don't like the pain associated with it. Some don't for more practical reasons like religion or family.
At the end of the day, it remains one of the few ways people who are artistically inclined can make a stable income. Being an artist is hard. Not everyone is getting classical works put into gallery's or selling them on the sidewalk. This is something that people will forever see and appreciate (well most not everyone will love their "mistake") themselves, show off, etc.
Watch it be something like their job doesn't allow visible tattoos ._ .
@@ramenguy2186 that would be hilarious
@Eldritch Abomination I have dozens of tats and never once have regretted it no matter who did it. Why wouldn't I trust them? Don't talk out of your ass if you know nothing of the culture. Tattoo artists are some of the most diverse and understanding people on the planet. I have seen it first hand.
@Eldritch Abomination As if a surgeon who had never performed surgery on themselves is bad.
Some operations require both hands to be free.
I meditated when I had my tattoo done, that's how I blocked out any pain and stayed still as possible for the artist.
The complete quote from Carl Sagan is used in the music video "Ad Astra" from Nightwish where they team up with World Land Trust to spread awareness of deforestation and animals getting extinct. Your tattoo looks very nice man.
Love that video! Nightwish are amazing, though not quite as amazing as Carl Sagan was. 🖤🤘
@@neuralmute they are amazing in their own way. As was Carl Sagan
@@rickyapril104 I mean, you can't compare kick@ss bands and astrophsysicists, really. Unless you're talking about Dr. Brian May. 😉
@@neuralmute I see what you did there 😂
I came here to comment the same thing. I had to go listen to Ad Astra after watching this video when I saw the quote.
Space plumbing is really cool. It’s a lot harder to separate liquids and gases.
Talk about perfect timing for this video to come out (for me), I've been looking into getting a tattoo! Thank you science man, very cool.
Reminds me when I used to do bat work. I assisted with virologists in the capture of bats, and the virologist would use a tattoo gun to mark the bats on the wing. At the time it was a relatively new technique, and the tattoos would be less stressful for the bats, as rings would cause chaffing on the bats wing. It also appeared to be successful, as I was there when they made a recapture of a bat.
The real question though is what did the bat get tattooed on its wing though? Was it something edgy like a skull with a knife through it? Or maybe a reassuring quote like Kyle got?
@@ZarniwoopIII That would have taxed the virologists skills, I am afraid. It was basically the date it was captured, along with an ID number
@@xenogil180 Your virologists should really work on their tattooing skills. Those bats deserve some sweet ink for science!
@@xenogil180 I wasn't being serious. Just trying to be funny. Guess I failed, haha.
@@ZarniwoopIII Not to worry, text doesn't always convey tone very well. I did find it funny after I answered.
My impression was that the needle was coated with ink, it dragged the ink threw the skin, so some ink came off the needle and stayed in the skin. One ancient form of tattooing, where a need was dipped in pigment then pushed straight through, under the skin, and pulled out another hole, creating a line from a single puncture, seems to work this way.
It’s hard to identify if, in the jello experiment, the color is drawn in threw static capillary action, or if the force with which the color was brushed onto the jello was pushing the color in, or if the deformation of the jello was drawing the color down. A better demonstration would have the jello in a clear, glass container, preferably with flat sides to reduce distortion, and to gently drip the coloring onto the punctured jello. That way we could see the color moving down the holes.
The ink appearing on the skin after the tattoo needle has passed suggests the needle could be pulling a lot of ink in with it, and the excess ink is pushed out leaving the tiny amount that becomes the tattoo. In fact, the ink appearing on the skin after the needle has passed strongly points to the ink being deposited de the action of the needle.
The better way to show that the ink is drawn in after the needle has made a hole, would be to puncture the skin with a clean, un-inked needle, then apply the ink to just the surface of the skin. If the capillary hypothesis it true, the ink will be drawn down, into the holes created by the needle. But I would guess the ink wouldn’t penetrate to be deposited as nearly well; and I wouldn’t be surprised if it didn’t leave permanent mark at all. You should be able to run this test with just a few, single dot tattoos.
The post-credits scene answered the exact question I was thinking. You are quite right that time has no meaning, especially if the Facility is hoarding all those time-crystals.
I think you're right but backwards. It would also make since that, ink being puddled first, would have its best opportunity to be drawn (lol) into the freshly made flesh vacuum tube
"You can look at the needles..." No, I infact cannot. 7 tattoos down and still cant :'D
Congratulations again for the first piece! The signals spreading from our lil planet is a wonderful touch.
Same. Multiple tattoos and piercings, still cannot look at the needles.
Those lines are on the Golden Record. They are a "map" designed by NASA that would theoretically allow an advanced alien civilization to determine the location of our Sun, if they find the Voyager probe.
@@yondaime500 Oh neat, thanks for telling 👍🏼 I was thinking on the lines of the signals (radio?) we've sent out from earth and how relatively short distances they've travelled so far, in the grand scheme of things.
jesus christ. that took 4.5 hours? my entire forearm piece outline ( which is quite detailed, i drew the piece and the artist actually had to make a judgement call to adjsut my original piece because some parts were too detailed to show up well in a tattoo) the outline took 4 hours and it was for my entire forearm. kind of wild that took 4 hours. no shame on the quality, it looks great and lettering is touchy as hell. just surprised by the time it took.
I hope your tattoo heals quickly and the line work stays clean!
I love the little hint of the golden record pulsar map as the shimmering glimpse of the earth!
Hey Kyle: why the tattoo don't completely disappear with time? I mean, our cells are always dying and new ones appearing... why the ink continues there?
Ink particles are too big for your body to separate… If they wouldn’t be, ink would go into your blood and then into your urine (I know I’m not Kyle, but I hope you find that helpful 🙂 )
Your white blood cells nom the DANGEROUS INVADING MATTER (ink bits), preventing it from being shed with your regular skin. When the white blood cells die and the ink is free again, more white blood cells nom it. There’s a bit of loss over time, but for the most part this quirk of exploiting the body’s defensive systems keeps the ink largely exactly where you put it for a very long time.
Also that what tattoo removal does. The laser breaks apart the large particles, allowing them to exit the body.
Well, your body fights the ink over time and the particles, heavy metals, end up in your lymph nodes. Let's just say you do not want ink deposited and sitting in the lymph nodes as it will cause health problems. Also tattoo ink isnt regulated so who knows what the composition that is used. Studies are still being done but we know what happens when heavy metals, some carcinogenic deposit in the body.
i have 1 tattoo, and after 3 days i still don't regret it. i see this as an absolute win

The tremble is his voice at the beginning lol, happens every time you hear that buzzing no matter how much tattoos you got
Ok so it's been like... God 12 years since my last tattoo... These things don't have cords anymore?!?!
What a time to be alive...
The thing had buttons and LEDs at the top too. That shit threw me off a bit.
Don't forget daily care until it's all healed up! Looks awesome.
Always wanted a sleeve of a bee hive because I love hive minded organisms. Cool to learn more about them, thanks for the video.
"Anthing for science" is a very dangerous thing to say to a super villain
Kyle!!!!! I've been looking for new Because Science episodes for a year now, and I just saw someone post in the community that you have your own channel! I'm sad it took so long to find but so excited to see you're still active and now I have a ton of content to catch up on!
Dang it Kyle! for once I thought cool I already know this! But no you had to be all thorough and teach me even more about how tattoos work
There is one thing that bothers me about the tattoo. Mostly because I'm a picky bastard that thinks too much about stuff that bugs ME. If I had that same tattoo I would have flipped it upside down. BUT, that being said, Kyle did say it was more for him. He wants to look at it as a personal reminder. Now, if it wasn't for that, I would have flipped it upside down so it would be easier to show other people who are in front of me. Otherwise, it's a cool tattoo. Simple but effective. Hopefully there are more to come.
I always point to shirt graphics.
@@MrInfinity418 You can point to shirt graphics and I'll point to nurse's watches.
A shirt is for other people to see but a nurse's watch is for them to see so it's "upside down" for everyone else.
Some people have tattoos that are for them.
@@phyphor all tattoos are for the person who got it. A watch is a tool. A tattoo is a graphic.
@@phyphor btw you can get your tattoo however you want. I am however a tattooer and do use shirt graphics as reference for flow and general layout. I point to how you could want future tattoos and then really start considering orientation and layout as a whole. Then you would start to feel like your current tattoo is upside down. You got it on your skin…it’s obviously for you. You should be able to get the meaning with it facing the other way.
Not only can I get a tattoo the way I want, I did get a tattoo the way I want. As did Kyle. And I've had mine for so many years I can't remember how long I've had it, and it isn't upside down, because it's the right way up *for me*. I didn't get it for anyone else. I got it *for me*. And, again, your comparison to "shirt graphics" is countered by my comparison to nurse's watches, or fob watches, where the point is that it's visible to the wearer, because it's for them.
I've used a surgical blade to cut into my skin then firmly rubbed graphite paste into the wound and left it to heal normally, it's been 15years, it's still here
I felt so bad for laughing so much at that breakdown. But, I needed that. So thanks.
I have 4 tats so far (more planned) and it goes the same every time:
First 5 mins: lightheadeness, get super pale, nearly pass out
After the first 5 mins: totally fine, color returns to face, don’t feel like passing out anymore.
Never understood why. I don’t feel queasy around blood or needles, and my pain threshold is average. It always been interesting to me.
"oh no, I'm still worried about pain" mood tbh
i got a tattoo when i graduated! its a quote from a choir song we didnt get to sing (u know,, covid) and my choir teacher wrote it for me! it says 'you are breath, you are life, you are beauty"
we’re gonna need a illustration of Kyle, full mad scientist regalia, proclaiming, “welcome to my squishy jelly lab! MUHAHA!”
Why is ink also found in lymphvessels and lymphnodes? It is said in studies that tattoos can cause auto-immune diseases and cancer. Biological ink could be broken down by our cells, so the ink used for tattoos are mixtures of substances, which are toxic. The longterm effects are still not investigated.
I have one on my lower forearm, just above the wrist. I have very low pain tolerance and it hurt like hell.
I'm very proud of it by the way.
Welcome to the "club" science Thor -- let's just hope you don't get addicted to tattoos now -- they kinda are like Pringles - once you pop you just can't stop 🤣
Just did a tattoo for science - that is real dedication to science communication.
The needle is still injecting ink though, or rather carrying ink beneath the surface of the skin, as it passes through the ink as it penetrates the skin, carrying ink into the hole. This may actually be of aid to the seeping process, as the ink in the hole, and the ink on the surface are going to be linked forming a sort of channel which the ink can move along, and the hole will be the space they fill.
The patent is available for a tattoo gun. It is basically a repeating injection needle.
Doing what you are doing would cause someone's skin to change color.
Good explanation of how the ink gets into the skin, but I kind of wish it took a bit to explain how tattoos stay around. The whole cycle of macrophages eating the ink, releasing the ink when they dye, and the ink being eaten by new macrophages pretty interesting. But I suppose you have to focus on one thing or it gets unfocused, so it makes sense why it was left out.
Really neat "hacksmith" mask. And nice tattoo.
Tattoos are just ultra cringe no matter what
Congrats on your first tattoo - I can’t think of a better design to have. The Pale Blue Dot is my favorite quote/monologue/passage from Cosmos. I think I’ll watch it again now. 💫

Duuude, i was so planning on having a similar tattoo done one day (featuring the "pale blue dot" quote and image).
I love getting inked, it's the best therapy and properly chilled, I often struggle to stay awake and the buzz of the pen is surprisingly relaxing, only one more session to complete my colourful Hawaii sleeve.
My tattoo artist, Jak, who I'd highly recommend from Sakura Tattoo Studio in South Gosforth, Newcastle upon Tyne in the North East of England, wishes he could do more full colour tattoos for people, but everyone seems to just want black and shading. Get creative people and make your skin exciting!
That tat was almost all linework. That was the most painful part of my tattoo. Like a buzzing knife. Real hard to hold still through that.
I mean in the past Kyle basically sold his soul for content, so a tattoo seems small in comparison
"I need attention from strangers. Oh wait! I know! I'll permanently alter my body with ink."
Gotta admit the pale blue dot is a pretty amazing tattoo
Congratulations on your transition Kyletta!!!
I'm covered in ink and I've always thought it as its stabbed into the skin and held in by the body.
I'm currently trying to embroider that pulsar map and ... i"m weeping.
7:28 - "If I don't turn my entire life into content, how will people know that my life has any meaning?"
Easy, get a tattoo with meaning...
my first tattoo was fun my tattooist freaked out because I got board fell asleep he thought I passed out love the vid keep going mate
I did my research on tattoos before getting them. Wish this video was made 8 years ago lmao such a simple explanation, nice.
Nice video! What's also worth mentioning is the biology behind tattoos. The ink doesn't entirely sit passively in the skin. It is a foreign body after all and our immune system will react against it. After getting a tattoo, a part of the ink will be ingested by macrophages, which will usually stay at the spot where the ink is initially placed but some of them will move, and some eventually dye and get reingested by other macrophage cells. What we see as a tattoo is not only "the ink in the skin" but also, for the most part, a collection of our own immune cells trying to eat up and digest the foreign body. And it is a dynamic system. As time passes, and these macrophages migrate, some of the ink might be lost or displeased causing the tattoo to possibly fade and become less sharp over time.
This makes me want someone to film a tattoo being done on high-speed camera so you can watch it happening in slow-mo...
I love how Kyle explains what blow outs are and how they happen in detail but doesn't directly mention it.
With your demonstration I'm curious how it would change the amount of "ink" if you placed it on the "skin" before puncturing it.
Kyle, that's an awesome quote for a tattoo.
I literally just made an appointment for my first tattoo a few days ago. Thanks for the video. I'm a little less nervous about it now 👍
The problem with this theory is your body doesn't leave a hole when the needle comes out. Nearby blood cells release fibrin and then white blood cells flood into the area. The result is a liquid being push through the hole and from your body. No capillary action can take place against counter flow. Remember on a microscopic level, tattoo needles are rough and blunt. I suspect the needle simply "grabs" the ink, forces it into the wound, and some of the ink is left behind when the needle retracts. Also when artists do multiple colors it's common for a puddle to form over previous colors but we don't see everyone's tattoos looking like watercolor. You could have been tattooed without any ink and then simply pulled the ink on top of the wound to try to prove your hypothesis.
"oh, no, I'm still worried about pain"
lmaoooo
"Sic Sagan tat, brah!"
I think Kyle wanted a tattoo but then was like I want to document this in a scientific manner and made this. Looks good Kyle 👍🏻.
id buy that t-shirt but personally, sorry kyle, i think imma coppy that tattoo the pale blue dot picture has always been an awe inspiring thing to me and carl sagan is a true hero
At least you will have a way to get back home if any unplanned interstellar travel occurs.
