Theoretically, unless they're going for arcane tattoos or something, I am unsure how well using the body as a physical medium for arcanima formulae would work. And, if you do tattoo them on, would the materials that are used for the best dyes... safe to have in your body?
And even after all that, you are using the aetherical formulae as a focus to cast your spells. Having them tattooed on you wouldn't suddenly give you the ability to cast magic, I would think. Or even help or hinder your natural aetheric ability. You'd just have a potentially stylish alternative to having a codex on hand - if you think having equation ink is rad.
Which, I suppose, could be handy. Since you could technically never be disarmed - you have your spells with you at all times. Which might be handy.
