Hi Robert,

I`ve been trying to mark my kid`s birthmarks with a blue ballpoint pen. My son however would have none of it. I think he found it ticklish and painful. So what I did is cut open the ballpoint pen and smear the ink on his birthmarks. This he doesn`t seem to mind.

I was just wondering now if this is ok, as I read that you think it`s the blue ink that helps the process and not necessarily the circle or other symbol you draw with it?

I must say I find this method a lot more practical, even for myself as sometimes the ballpoint is a drag to apply when you have oily skin.
