Besides the design you chose, another part of proudly showing off a tattoo is reminding others of all the pain you endured to get it. But that might not always be the case, as researchers from the Georgia Institute of Technology have found a way to borrow a new medical technology to create self-applied tattoos that don’t cause any pain at all. What gives tattoos their permanence is also what makes getting inked so painful. Tattoo artists use needles to inject tiny drops of ink into the dermis layer of the skin, just below the surface, so that no matter how many layers of skin naturally come off over time, the ink remains safely trapped beneath that self-replenishing outer layer. Pain is a big part of the experience of getting a tattoo, but not everyone goes through that process by choice. Tattoos are often used as a medical tool, too. For example, cancer patients going through repeated radiation therapy treatments are tattooed with small reference marks allowing the machines, and radiation beams, to be quickly, accurately, and safely targeted each time. Tattoos can also be used to help camouflage post-surgery scars, or provide permanent warnings about serious medical conditions for some patients. That led a team of researchers from the Georgia Institute of Technology to come up with a way to use microneedle technology as an alternative tattooing technique. As the name implies, microneedles are small enough to inject drugs or medications into the dermis layer of the... https://www.pinterest.com/pin/513691901251889747/.
L letter tattoo designs on hand These same pigments are used in tattoo inks." This means modern tattoo ink is sometimes made from products that were not manufactured for tattoos – including printer ink. "Our focus is that we want to understand the science better," Swierk told ABC News, "We want to empower artists and consumers to be knowledgeable." STPCK PHOTO/Getty Images The team of researchers uses multiple techniques to detect the particle size and molecular composition of tattoo pigments, using highly specialized machines that can analyze the inks at a molecular level. "The most surprising thing we found is just how much inaccuracy there is," Swierk said. "I won't say that it's inaccurate for every single manufacturer … but certainly, we've looked at a pretty significant subset, and we're finding a recurring issue of incorrect labeling." The team has been studying both carrier solutions – which Swierk said is the liquid portion that carries the pigment, typically made out of a mix of alcohol and water – and pigments. In 20 of the 24 carrier solutions examined by the team, they found alcohols that were not listed on the label, Swierk said. Another aspect the team studied was particle.

These range from the names of ex-partners to tattoos done on vacation. They also spoke about ways you can avoid tattoo regret.
L tattoo with heart While the average rate of a tattoo artist is about $150 an hour, and the price for a small tattoo is around $45, the average cost of laser tattoo removal is about $423, according to according to 2020 data from the American Society of Plastic Surgeons. The poster has raised the issue with her boyfriend in the past, but he's always told her that the tattoos don't bother him, as he can't see them, and that he'd rather spend the money on them instead rather than get a tattoo removal or cover-up. In the comments, she reassured readers that she won't leave him over a few awkward tattoos because she loves him, and they're about to have a baby together, but she has felt "a little sad when [she's] lying next to him and that's all [she] can see." She said she was already wondering how to explain this to their baby when they get old enough to read.

WireImage But 6ix9ine says he had nothing to do with either documentary and didn’t even “recognize the voice in the documentary as mine” in which he supposedly talked about how his name came from Matsuba, the affidavit says. “And for the record, that statement is not true,” said the affidavit by 6ix9ine. 6ix9ine’s lawyers say Matsuba’s claims show “hubris” in that he “seeks to commandeer and restrict the use of his common Japanese first name,” court papers from Wednesday say. Lawyers for Matsuba and 6ix9ine declined to comment.

School of Chemical and Biomolecular Engineering, presented the research in the journal iScience, with former Georgia Tech postdoctoral fellow Song Li as co-author. Tattoos are used in medicine to cover up scars, guide repeated cancer radiation treatments, or restore nipples after breast surgery. Tattoos also can be used instead of bracelets as medical alerts to communicate serious medical conditions such as diabetes, epilepsy, or allergies. Various cosmetic products using microneedles are already on the market mostly for anti-aging but developing microneedle technology for tattoos is new. Prausnitz, a veteran in this area, has studied microneedle patches for years to painlessly administer drugs and vaccines to the skin without the need for hypodermic needles. “We saw this as an opportunity to leverage our work on microneedle technology to make tattoos more accessible,” Prausnitz said. “While some people are willing to accept the pain and time required for a tattoo, we thought others might prefer a tattoo that is simply pressed onto the skin and does not hurt.” Transforming Tattooing Tattoos typically use large needles to puncture repeatedly into the skin to get a good image, a time-consuming and painful process. The Georgia Tech team has developed microneedles that are smaller than a grain of sand and are made of tattoo ink encased in a dissolvable matrix. “Because the microneedles are made of tattoo ink, they deposit the ink in the skin very efficiently,” said Li, the lead author of the study. In this way, the microneedles can be pressed into the... .

Enlarge / Scientists have found that tattoo ink ingredient labels are often inaccurate, and some inks contain nanoscale particles that could harm human cells. Kymberlie Dozois Photography/Getty Images reader comments 178 with 116 posters participating Share this story Share on Facebook Share on Twitter Share on Reddit Scientists at Binghamton University (State University of New York) have analyzed nearly 100 different tattoo inks and found that the manufacturers' ingredient labels (when used) are often inaccurate and that many inks contain small particles at the nanoscale that could be harmful to human cells. They presented their findings at this week's meeting of the American Chemical Society (ACS) in Chicago. According to principal investigator John Swierk, a chemist at Binghamton, the project initially started when his group became interested in tattoos as tools for medical diagnostics. This shifted to an interest in tattoo laser removal, specifically how laser light causes tattoos to fade.

About half of the 18 inks analyzed with electron microscopy had particles in this worrisome size range. Enlarge / Colored ink bottles jumbled together in a box at a tattoo parlor in Berlin. John MacDougall/AFP/Getty Images The European Commission has recently begun to crack down on harmful chemicals in tattoo ink, including two widely used blue and green pigments (Pigment Blue 15 and Pigment Green 7), claiming they are often of low purity and can contain hazardous substances. "Anybody getting a tattoo in the US with blue or green tattoo inks should assume that those pigments of concern are going to be included," said Swierk. "Most tattoo manufacturers are discontinuing the sale of blue and green inks in Europe [in response to the regulatory crackdown], not necessarily changing pigments, because there's no obvious replacement at this time." Advertisement However, he added that while the EU's scientific data is concerning, it's not the definitive conclusion just yet as to the overall safety of the pigments.
