This is awesome and I hope it catches on, but the idea of "may be useful to people who want to conceal tattoos in some situations" seems far fetched, some make-up layer would probably be a simpler solution, wouldn't it?

Hot springs and baths in parts of Japan deny entry to anyone with tattoos

Usually a bandage will suffice to cover it. Even for very tattooed people, can be quite liberal with it.

> Even for very tattooed people, can be quite liberal with it.
Is this true for all heavily tattooed people, or are they more understanding if you're not Japanese?

In my anecdote, the tattooed person was Asian but non-Japanese. We did this several times, but of course it's still a small sample size, so take this with a pinch of salt.

Yeah, I guess now’s time to do the groundwork for building a tattoo empire in Japan.

> These dyes are encapsulated in nanoparticles of polymethyl methacrylate (PMMA) — a medical-grade, glass-like plastic that is already used in medical implants and dermal fillers
Nano plastics? :p
Still pretty neat. I like the example picture in the article too

That is so cool. I wonder if this allows for printing images with some kind of 3d printer like thing with a weak uv laser

Got me in mind of the people nowadays "renting space" across their body - this would be an ultimate form ...

I'll have to read up on this. I wonder about it as a kind of e-ink?
I'm sure there are a bunch of differences, but fun to think about perhaps.

So just fill your skin with this ink and use a laser to print any pattern.
Looking forward to see human ads

A cool concept, but regular daylight making it disappear again sounds pretty annoying.

Regardless of the actual tech here, "he turned his tattoos off" has "the door dilated" vibes. Very cool.

This probably has some cool applications for magicians to do unique tricks where certain things appear on their skin.

Instead of focusing on tattoos, could we work on this being used for bistable displays, like e-ink but using light pulses to transition each pixel?
Because skin is not just loosely hanging on but is attached to the tissue below.

Does it turn the lymphedema off too?

Lol. Allow to violently perforate your skin with a set of sharp needles to permanently inject a pigment that can be hidden.
Just wear a baby skin sticker!

Piercing is one big perforation.
Tatoo is a process of continuous small perforations sometimes for many hours.

An alternative to "customizable/dynamic fashion" like this would be tags/markers on people's clothes that are invisible to the naked eye but can be detected by AR glasses, making you appear to have different clothing, accessories, tattoos etc to people wearing those glasses.
But man none of the major company execs have a hint about any of the cool applications of AR sigh

Your auto-immune system does not like ink.
yahthatsart 5 hours ago [-]
You don't have an "auto-immune system". Auto-immune means your immune system is attacking your own healthy cells.
Tattoos are fine. There's some evidence that maybe, maybe, immune system responses can be impacted by tattoos. But changes in immune system response does not necessarily mean impaired or negative.
oversimplifying but in every person there are tradeoffs about attacking things inside yourself (viruses, cancer, etc) and outside things (parasites, bacteria, etc) and your genetics influences this. See the old Th1/Th2 balance
anyway it was probably a typo on his part, he's such a sleepy guy..
