Although it's not clear what kind of writing you are asking about, I will assume you mean writing with a surface-level demarcation like a pen, marker, etc. without penetrating the skin. In that case, this article explains
One who writes on his skin without making a cut in the skin which allows the ink to penetrate is exempt from Biblical liability. [Shulchan Aruch 180:1] Nevertheless, some Poskim [Beis Shmuel E.H. 124:16] rule it is Rabbinically forbidden to do so. It is however unclear if this applies even with ink that is erasable. Other Poskim [Shevet Halevi 3:111-1] rule it is permitted to do so even Rabbinically. Practically, the widespread custom is to be lenient even initially. [Rav Shlomo Zalman Auerbach quoted in Nishmas Avraham Y.D. 180] However, if the ink is permanent and cannot be removed at all from the skin even with the passing of time, one is to be stringent. [Minchas Chinuch Mitzvah 253:1]
