Do you mean it's showing on the scanner as metal? My understanding is that some colors have metal oxides, like red.

It’s the number one best protection for your tattoos. If you have 10 grand invested into your sleeves you certainly don’t want to expose them to the sun.

This is really interesting I’m going to share this with my artist. Thank you

A question I've always had: why are inks for dark skinned people so limited? Yes I know there skin absorbs the pigment in the ink (correct me if I'm wrong), but shouldn't someone by now have created an ink in the major colors for true black skin?

Where we’re you when I was doing my PhD? As a chemist who used to work in tattoo shops and is fairly covered, this is an area I was always interested in! Pretty cool and I’m looking forward to reading the papers.

Can’t directly weigh in, but what I am aware of is that nanoparticles of TiO2 interacts with UV absorbers in sun screen to accelerate the breakdown of aromatic sunscreens into toxic substances, from doing research for a paper on that topic.

So, it is possible that TiO2 might interact with the other components of the ink.

if you want to avoid carcinogenic ink, try avoiding getting it injected into you. Can't imagine how anyone would think ink would be benign after being injected into living tissue.

So I’m aware they haven’t found evidence that tattoos can lead to cancer but my question is; is that because they haven’t done enough studies and it’s a low priority in the science community? Or have there been an adequate number done to mean it’s most likely safe?

I was actually planning to get my first tattoos next week but have been on the fence and have certainly wondered about safety.

Interesting. I wonder how much a persons personal biology plays into the degradation of ink in conjunction with external environmental factors.

Tattoo artist for 15 years

Blue and green are hardest to remove with lasers.

Red and browns because they have metal oxides is what ive found most folks to have an immediate reaction to. If im using a bunch of reds or browns, i will do a poke test under the arm just to see if there is a reaction.
