Is It Bad To Write On Your Hand In Pen?

Writing on your hand in a pen is something many of us do, but is it bad for your health to write on your hand in a pen?   As a nurse, I do this ALL THE TIME and I often get told by some of my older patients, “that is a bad habit, and it will give you ink poisoning! “. But does writing on our hand in pen or a sharpie bad for our health and skin?

Writing on our hand in a pen will not affect your skin. Lucky for us, your skin is always shedding, and even if your naughty and don’t wash your hands thoroughly throughout the day, the pen or ink will come off over the next couple of days. This is due to our dead skin cells constantly shedding and flaking off into our environment. Any pigment that is left on the skin’s surface will eventually flake off.

In saying that, there is really no available evidence (please comment below if you have come across any), that has looked into this over a period of time. There are many blogs and online forums that discuss if writing on your skin in ink is harmful. It appears to be a common consensus that it is not harmful long-term. However, there is no available research to prove if writing on your hand in pen, long term has no health effects.

Can you get ink poisoning from writing on yourself?

Most pens are non-toxic, as long as you are not breaking the skin or using ink over broken skin you shouldn’t have any health effects from the ink.

As a general rule, ink pens such as ball-point pens, fountain pens, and felt tip pens contain a small amount of ink, so little that there is not enough to cause poisoning if sucked from the pen. There have been some incidences of some pink causing irritation and soreness around the mouth if swallowed in large amounts, but serious poisoning has not been reported.
