An appointment with the beloved tattoo artist is hard to come by, so Tuan made his visit worthwhile. Since debuting in 2014, K-pop star Mark Tuan of GOT7 has been steadily adding to his tattoo collection — a smiley face here, a butterfly there, and, of course, his birth year. Now that he's back in his hometown of Los Angeles, Tuan made a visit to famed tattoo artist Dr. Woo for a new addition earlier this week. On Wednesday night, Tuan teased his appointment on his Instagram Story, building intrigue among fans (and curiosity among Allure editors). About 24 hours later, Tuan finally revealed his new body art for the world to marvel at.
