The Koebner phenomenon, in which psoriasis flares can be triggered by damage or trauma to the skin, is a very real consideration for those with psoriasis and tattoos. For Williams, nothing happened after her first tattoo. “My skin was fine after getting the tattoo,” she says. “But over the last four years, as my skin got better and worse, I have had [psoriasis] patches pop up over my tattoos.”
Williams says when the lesions heal, the tattoo is unaffected.
“At the point when I got my first tattoo, my skin was at a good place, and I didn’t have any reservations about getting it done,” says Williams.
Rue Monroe, 28, Davenport, Iowa

Rue Monroe, who works as a librarian, was diagnosed with psoriasis at age 2 and has a total of seven tattoos. She got her first tattoo at age 24 – a small crescent moon on her inner left wrist – to pay homage to the Pagan religion she follows.
When Monroe got her third tattoo at age 26, an hourglass on her right calf, a patch of psoriasis soon developed. “The patch of psoriasis was diamond shaped and just touched the border of my tattoo,” she says. “I’m happy it didn’t spread and take over my tattoo, at least!”
Shannon Hall, 31, San Antonio, Texas

Air Force veteran Shannon Hall had never heard of the Koebner phenomenon and the effects prior to getting tattooed.
“I didn’t know that damage or an injury to the skin could cause a flare-up, and that wouldn’t have changed anything anyway. I love my tattoos, and after this current flare-up is gone, I will be getting more,” says Hall.
“Psoriasis is not curable, so I’m not going to let it stop me from living,” she adds.
Hall got her first tattoo at age 19 – a cherry blossom on her lower abdomen. Luckily, she has never had any reaction to getting tattoos. She now has a sleeve (full length arm tattoo) and 5 other tattoos, all of which hold deep symbolism for her. For instance, on her foot is an infinity symbol, which represents her refusal to “sink because of the obstacles,” Hall says. “It’s a reminder of what I went through and that I’ll always make it.”
The Koebner Phenomenon and Other Concerns
In the late 1870s, Heinrich Koebner first detailed the phenomenon that would come to bear his name. He was describing the appearance of psoriasis plaques on skin that had experienced trauma and was previously unaffected by psoriasis. [1] You may also hear this referred to as isomorphic psoriasis. It simply means that the plaques resulting from trauma are similar in presentation to the plaques on skin that was previously affected. The Koebner phenomenon impacts approximately 25 percent of people with psoriasis after traumatic injuries. [2]
Beautiful and meaningful as tattoos can be, it is undeniable that they require trauma to the skin. During the tattooing process, a specialized type of needle with tattoo ink goes rapidly in and out of the top layers of skin to outline, shade and color the skin. If someone with psoriasis gets a tattoo, there is a significant chance of inviting the psoriasis plaques to the tattooed area. You might go into the tattoo parlor with scalp psoriasis, for example, and after getting a sleeve, you could start to see psoriasis plaques on the arm.
If a tattoo is important enough to you to proceed despite the risks associated with the Koebner phenomenon, there are a few other things to consider before hopping into the artist’s chair.
“A tattoo done in nonhygienic conditions can [lead to] an infection,” says Nicolas Kluger, M.D., Ph.D., senior dermatologist in the Department of Dermatology of the Helsinki University Hospital in Finland. “Of course, the main complication is regret.”
Risks and regrets noted, Dr. Kluger says that tattoos can have a positive effect on self-image. “We saw in some studies that for people who have tattoos and psoriasis or skin disease, the tattoo can have a positive impact on body image,” he says. According to a study, he adds, “people with tattoos found themselves more beautiful or more attractive.”
