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?

> 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

So just fill your skin with this ink and use a laser to print any pattern.

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.

Despite the limitations, that is dope as heck.

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?
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!

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.

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..
