Tattoos have long-ago lost their negative stigma. Now they are a commonplace and (mostly) accepted art form. Because of that, many artists have taken inking the skin to a whole new creative level. Pis Saro, a Ukranian tattoo artist, is a prime example of that. She bases her tattoo designs on watercolors and uses human skin as a canvas for some delicate and beautiful work.
You can find more examples of her work on her Instagram.
