Professional Tattooer here: Always love seeing deep dives on the craft and want to throw a few things out there. Personally I tattoo around freckles, and skin markings of the like, just in case they change shape and if asked any tattooer would comply with your concerns. Any reputable shop anymore will never reuse equipment aside from the machine , tray and spray bottles which are heavily sterilized with hospital grade cleaners (Madicide / Cavicide) making infection / disease risk miniscule , usually any infections come after individuals leave the shop through unintentionally resting their new tattoo on dirty surfaces or cuddling up with their pets or just flat out neglect Plastic barriers are placed on everything and thrown out after each tattoo. The cost on products has gone down tremendously since "the olden days of tattooing" and are mass produced (IE Needles) it wouldn't even be worth it to use the same needle on two separate individuals, you'd be surprised but that is still a common concern and question for some folks This'll prolly get buried but feel free to drop a question if you got em !

I did thousands of MRI scans and had maybe a half dozen of people complain about a burning sensation in their tattoo. They were usually newer ones with lots of red pigment, the radiologists theorized that it might be iron oxides in the red ink, which would make sense because iron is strongly affected by magnetic fields.

as a tattoo enthusiast, I really appreciate this video.

Another random risk factor left out - keloids! I was warned as a child to avoid tattoos and piercings, as I have a tendency to develop keloid scar tissue. I developed one the first time I tried to pierce my ears.

I was told by an ER doctor that it looked like I had breast cancer at 30 yrs old and had to get a mammogram... it ended up being a calcified lymph node due to a giant tattoo on my entire rib cage. Tell you what- I was terrified till I found out it wasn't cancer!!

Omg, I never want to pollute my Dermis .. ever

As a heavily tattooed person, I appreciate this breakdown. I’ve been undergoing laser tattoo removal on a couple of mine and understanding that process makes this all the more interesting.

I got a infection on my ankle after a tattoo. It was a rainy, muddy week. Just like any wound, aftercare matters and I was trying to keep it clean but bacteria still found a way in

I live in a holiday destination and work in same people from all over the world visit mostly in 21 to 40 yo bracket right in tattoo age group heres the thing i have become good friends with regular tattoo artists that visit they tell me they do ok but nothing like the business they had a decade ago ...2009 to 2015 was peak interest is slowly dropping off now ... They added and said in our city of 3million in 2 years only one other tattoo shop opened And 6 laser removal clinics have opened and climbing

My oldest one--a butterfly--is 45+ years old. Other than needing a touch-up due to fading, I've had NO negative reactions to the ink. Reactions from other people, now--that's another story.

Can you make a video of how to improve the quality of sleep? There are people who have trouble sleeping or wake up in the middle of the night and can't get back to sleep (including myself) I would appreciate it very much 🙏

Ayyyye you took our suggestion! 😉

For decades black velvet paintings were sold on street corners and at flea markets across our nation. They were enthusiastically purchased by some and reviled by others. I haven't seen one in years. Tatoos remind me of black velvet paintings.

Starting with metallic inks as one of the 'random' risks was cool, reminds me of the House M.D. episode where a guy on death row gets stuck in an MRI and it starts trying to suck the tattoo ink out of his skin due to his prison tattoos including heavy metals in the ink. Nice to know that show wasn't complete fiction.

Every time I've had a tatt done the artist has definitely reminded me that it is essentially an open wound. It might look pretty, but bacteria and your body don't know the difference. Awesome video!

I saw some information that tattoos can affect autoimmune diseases. Because the ink is detected by the body as foreign, it can flare up the immune system. If you have autoimmune conditions like lupus, rheumatoid arthritis, etc, there could be a risk of flare-ups of the condition after the tattoo. So many things are being found to be associated with autoimmune issues, even common conditions like diabetes, thyroid disorders, irritable bowel symptoms.

Just a PSA: I'm 44 and recently did a hair analysis and I have an extreme aluminum and nickel toxicity. The doctor said this was very unusual. This affects kidney & thyroid function, and triggers terrible migraines. I otherwise live a very healthy lifestyle. My unique trait: I am heavily tattooed.

I love all my tattoos. Each one means a lot to me and has a meaning to a special time in my life. 😊

Ayo i got one last night and then u dropped this. What lovely timing

I love your videos Jonathan ! I wonder could you make one on breast implants? I would love to know more about some of the techniques surgeons employ - locating the implants over, under or splitting the muscle, the capsule formation, the silicone release, the impact on the organs, how BIA ALCL implant cancer develops, impact on lungs and respiratory system, removing implants, capsular contracture and tribology of an implant and impact on soft tissue in the chest. Thanks! Great videos! JJ

Sometimes, tattoos can create anxiety if you made it particularly big or covering a big area through one session, as it happened with me. I have many tattoos, and the last one I made on my back, covering it, created severe anxiety affect upon healing. Obviously, it was related to the inflammation, alcohol consumptions several days earlier, and overall exhaustion. However, anxiety rooted and I discontinued my tattoo coloring on the back leaving it partially finished. Tattoo removal is even more painful process. Even small tattoo removal may cause skin decoloration (white instead of natural a bit tanned for me). Thus, these videos are very nice to watch because they contribute to a better understanding how tattoos work and there is nothing super serious about them affecting the body. Consequently, less anxiety as in my case.

I've been watching your channel for 3-5yrs (I can't remember but since COVID). A big thank you for educating! 👍🧠💥😎🌌🤩📚🌟🌟⚖️🕊️💫🤍🔥✍️📝

I'm heavily tattooed and have also worked in a tattoo shop (as a piercer, but have tattooed myself and on some close friends) and I think this would be mandatory information on every website for any place providing tattoos. I want to point out that even if the tattoo studio have a good reputation it sadly can come down to chance. I've come across a guy that I let try my latex gloves if he was in need if he runs out of gloves. The dude gave me back the glove after he tried it... I don't don't think I need to say much more. Sure, gloves are not that cheap, but you absolutely don't reuse a glove, a needle or anything really. I don't have any insight to any numbers of cases or anything but my guess is that there shouldn't be as many cases of infections or the alike nowadays because of how easily accessible and cheap disposable needles and grips have become. At the same time, it has become much cheaper over all, so almost any person can afford to buy the equipment. And so without any real knowledge of either the function of the body or tattooing in general. I've had reactions against different pigments twice, and both times it was red pigment. To my knowledge it's usually green and red pigments that people usually react to. From the red pigment the tattooed area raised like it was swollen for a couple of weeks and got pores like 2-3 mm i diameter but not in a way that it looked symmetric or what I should call it. It was not a certain amount in a limited area. Where the pores was there is now no pigment. The rest of the tattoo is OK but has some areas where it's not as intense. When I told the tattoo artist he threw away all the bottles of that red pigment, which shows he is really serious in my opinion. I am very sensitive in a way, but not for allergies. If i get gasoline or oil from cars on my hands I can taste it in my mouth almost instantly. The same with shampoo, oddly enough with dish-washing fluid. i suppose there could be just certain chemicals that "shines through". I'm also very sensitive to light, sound and vibrations, so I suspect it can be symptom or a "trait" of my possible ADHD/Autism/Borderline/Bipolar diagnosis. I live in Sweden by the way. For others in Sweden, I recommend utilizing the right to get blood work done to check if you've got infected after accidentally puncturing a glove or somehow otherwise poking yourself with a needle you've worked on your client on. This is free of charge for people working in this area and you are allowed for one test every year I believe. Remember, there's no direct point to do this directly when you have done this by accident. Instead wait a few weeks so that the possible infection can show if there actually is any traces of a infection of any kind. Please, if I am wrong about anything, point it out! I'm not trying to spread false information.

I have several tattoos and take cleaning new ones very seriously, especially after being hospitalized with necrotic cellulitis last year. I just had a baby, was careless and exhausted, and didn't clean open sores (from psoriasis, not tattoo related). Keep your skin clean, tattoos are pretty but are technically injuries to your skin! The first 3 days are critical. Wound wash and Aquaphor are your friend.

I've just started my apprenticeship in tattooing and I love the scientific perspective of the art form. ❤❤❤

The coincidence bro!!! Today I was looking around for a tattoo shop, but I wasn't to sure about going through with it..... Then you guys come in and make it even harder for me LOL

I would love to see more skin stuff. How cysts work or skin cancer etc.

I can always tell when allergy seasons starts because all of my tattoos become raised for a while. I don't seem to be directly allergic to the pigments, but they seem to make me more sensitive to my existing allergies.

tattooes are contagious. once you start getting some ink, soon your whole body will be covered with it 😂.

I thoroughly enjoy learning everything you teach us and that's why I am a long term subscriber to your channel. 💖❤️💖❤️💖

Nice video! 👍🏻 These were some really interesting facts about tattoos and what they do to the skin!

Excellent info again. Thanks!!😊❤🎨

I was in the Navy, but I never got a tattoo. I'm glad I didn't get one because I found out later I had a nickel allergy, and most tattoo inks contain nickel.

Very well explained, very helpful - thanks a lot!

Thanks for the video, Cheers from Australia I've been with you for about a year now, great content, I'm hooked 😅

🎉Super educational thank you! Always appreciate the videos!

Very informative video

Something else to keep in mind: a few years ago a study showed that 1/3 of the autoclaves in tattoo studios surveyed were NOT functioning properly. Just because there is an autoclave does not mean it is being properly monitored and maintained/tested for effectiveness.

Very interesting! I will share this with my kids!

Thanks for making this video!

Thanks for sharing 🙏🏾

Basically, thank you for sharing knowledge and notes for this being tattoos.

Intersting video, thanks!

Love your channel

I'm not a huge fan of Tattoos, but you gotta give it to the tattoo artists and engineers... Those are crazy! Especially the tattoo removal part

I was planning to tattoo my whole leg, but this video made my resolve waver.

My tastes change too much for me to be comfortable getting a tattoo. But, I love looking at a good tattoo on other people. I've never had anything against tattooing. As repeatedly stated, with a reputable artist and good after care they are relatively saft. I had never thought about what goes into making the ink. Mercury, cobalt, cadmium, chromium, and nickel Don't sound like things I want collecting in my lymph system.

Great video!

Science aside, it’s unsettling that there are just squares of skin laying around like carpet samples at the Home Depot

This is very interesting!🤔

Very cool video!!

Like how you put out information without being judgmental. "Just the facts".

One weird thing that happened to me with my tattoo; i got my tattoos in 2021, one on my right caff which was in march and one on my left arm in july. did the after care routine, healed nicely with no complications. a year ago in 2023 (2 years after having the tattoos), i got sick, went to the doctors (got tested for strep throat), and got antibiotics. After i finished the antibiotics, i took some probiotics to balance out. While i was taking the probiotics, my first tattoo on my leg, which is the oldest, starting flaring up and itching, ONLY duting the time i was taking probiotics. My arm was completely fine, and as soon as i stopped taking my probiotics, the flaring and itching went away and my tattoo went back to normal 🤔 like i said, both tattoos healed perfectly fine, no infections or anything that had red flags of improper care, and only my leg on flared, but not my arm! And they are still fine to this day!

What a way to start my day

Could you please also do a video of the health effects and risks of laser hair removal? Thank you!

Thanks!

NOT having a tattoo is the new having a tattoo!!

GREAT VID (I just started playing it)

“It’s going to be very fun” 😆 Great video as always. It was super unpleasant to watch the needles piercing the skin, lol… Looking forward to goosebumps and such…

Never been this fast 😂 can't wait to watch the video!

This channel is great

Does the laser remover have risks of causing cell mutations like cancer? Very interesting video. Changed my mind about getting new tattoo and having current one redone lol.

I have 19 tattoos and I'm only 23. Spent the last year and a half saving money and by so, stopped getting tattoed. Looking back, i miss my ink free body

Speaking of collagen, a lesson on EDS would be good!

I have tattoos on my body the one particular tattoo on my wrist that I got during my school days felt burning sensation when I went for MRI. The technician told me about it earlier to let them know if it hursts, but it was bearable.

Interesante Jonathan ❤❤❤❤

Just got my first tattoo a week ago so this came at good time! (not that I didn't research of course)

I am moderately tattooed and I have a spine injury, so I am in MRI machines pretty regularly. I’ve only had the heat up once which wasn’t the best thing to experience, but it wasn’t anything to make a big deal about.

Thank you for the video!! I've been getting tattoos before they were cool💜🙃

My sleeve appointment is coming up! Wish me luck!

Thanks for this. I wonder how my veins on my left wrist (where my tattoo were) handled the needles 😨 but now it's kinda faded though, it's already 2 yrs ago

One thing I've never heard anyone talk about is wouldn't laser tattoo removal increase the risk of skin cancer in the same way tanning or long term sun exposure would? It seems to me it would be very damaging to the skin while destroying the ink particles.

this puts my mind at ease, as a beginner tattoo enjoyer and haver. as a kid, adults scared me that tattoos CAUSE cancer. now im educating myself how to be more responsible and enjoy artwork on my body :)

Furthermore, if you're planning on becoming a criminal don't get tattoos. Why? Because when the cops arrest people with tattoos they also photograph all of your tattoos making it easier to identify and catch you in the future. Another reason NOT to get tattoos is that whether it's fair or not, people will silently judge you and make negative false assumptions about your character without ever even speaking to you. Is that what you want? Maybe so, but not so much when you are older and those same tattoos aren't so cool anymore. 🤷 😔

Yeah, I learned the hard way about overlapping tattoos why you’re not supposed to. I got one on my leg and then about a week later got another one 6 inches below it. The top one got infected and dripped drip sweat down into the other one. Oh buddy Was that bad! Pretty much the whole tattoo fell out. I still have the outline today but anything that was fill-in or color fell out and I mean that literally it fell out in the shower one day.

Not a mention on ink toxicity and the lack of regulation of tattoo ink is an important thing to not mention.

My friends wife got a tattoo a 32 years old and now she's 82 it was a boat sailing and it's not pretty

I, unfortunately, have not done well with the red and yellow ink 😢 But, damnit, my tattoos are fire!!!

V good. Tank u

Learned stuff thanks!

I want to get my tattoo removed - thank you for talking about this.

I have many tattoos all of them done in black ink only the reason's i stick to black ink less chance of reactions and unknown ingredients.

Unable to donate blood, atleast for an year, can be considered as a side effect...

As someone with alot of tattoos. I appreciate this video. However, I have been concerned about risks of cancers, tumours or diseases related to tattoos. Is this a possibility?

Great explanations, examples, and info! I don't have any tattoos, but my son does (b/w, not color).

I am definitely taking a small one at first just to check if my skin doesn't reject it

I need to get some more work done, I just find it interesting how it all works. I will never go to a non reputable artist, would not even let my best friend work on me.

I realize that everyone has their own opinions about getting inked. Personally, I’m convinced that it’s just a fad, like bell bottom jeans. At least I’m able to either toss my old jeans or bury them in the back of my closet. Being inked though…. Did I mention that it’s probably a great idea to start a laser tattoo removal franchise? 😬

For those who haven't had a tattoo. It literally feels like your skin is being carved because that's kinda what's being done. Once the outline is done and endorphins kick in, it's not as bad.

Can you do One on Piercings Like Ear Nose or body piercings?

I had an odd reaction to a tattoo once. It is a pretty big tattoo with a lot of red ink and I got is sometime in October or November. It healed up nicely, no issues whatsoever. However the next summer (July? August?) it became itchy and swollen for a few days, kind of like an allergic reaction and just as suddenly, it stopped again. Never had any issues with it since, nor with any other tattoo. I still wonder what might have been going on there.

My husband and I are both full body tattooed and had some MRI- we both didnt had any problems

Was talking to a friend last week about the fact that redheads often react differently to drugs, sun exposure, and various conditions. Is there any discussions of whether they react differently to tattoos in any way? Just curious.

I had a tat lasered twice--still needs more work. Having them lasered off hurts just as bad as having them applied!

I have multiple tattoos and i love them. I also have a hEDS and MCAS. Due to the MCAS i have “allergic” reactions to solid ink brand but not eternal ink brand and it only happens during flare ups. I don’t have experience with any other ink brands. It is one tattoo particularly and it is only the ink itself and not the yellow pigment. The yellow in my other tattoos have no issues, but the yellow in that one tattoo itches and gets red/hot and puffy on occasion. The rest of the tattoo that is in eternal ink and not in solid ink has no reactions. It’s very odd how the body works. Nonetheless i will continue to get tattoos.

What a marvellous and beautiful structure my skin is. I must now go and get 'No Regerts' tattooed on it. (Note that our guy has no tattoos.) Yeah, I'm anti, but hey, your body, your choice.

What about SMP - scalp micro pigmentation?

My immune system apparently hates tattoo ink. I have 4 tattoos, and within a year or so each one blew out. My brother and I have a matching tattoo we got for his 21st birthday-this was 10 years ago- his looks as clean and sharp as it did the day we got it. Mine looks like I got it done in a prison 40 years ago. Luckily only one of my tattoos is in a high vis area, and I’d like to get it removed eventually.

I have one tattoo that sometimes gets inflamed, like the lines become raised off my skin. It is seemingly random, kinda burns and itches. There’s nothing special about this one- all my tattoos are 6-8 years old and this one was from the middle of that. I have several dozen more and this is the only one ive had trouble with - even stick n poke india ink and BIC pen ink (dont do this, i was 13) have never given me problems. The tattoo in question was done with a bigger needle than I’m used to and I wonder if the artist used a different kind of ink than normal, but i have different tattoos from that artist that are fine. Its totally perplexing, the entire shape of the tattoo becomes raised and inflamed but none of the adjacent tattoos or skin are affected. I wish someone knew what this is!
