Is that risky? Like dummy-taping and how your skin can't breathe or you can over-heat. :O

Actually... the whole thing about one's skin not being able to breathe is completely an urban legend. It may not have started with that old JAmes Bond movie, Goldfinger, but was certainly popularized by it.

Frogs and salamanders may breathe through their skins (partially), but human beings don't. You can paint every square inch of your body without having a problem with that.

As for overheating... that's a misconception too. At first, I worried that would happen... but then after I put it on, I realized that it is very difficult to overheat when all you are wearing is a layer of paint that is about the thickness of a sheet of typing paper - or less... and which is directly on your skin so that there is no air-space insulating you.

I suppose that it could interfere with your ability to cool off by sweating a bit, especially if you put it on thick... but when I've worn it, it actually turns out to form lots of little micropores when you move around. Some of your sweat actually comes through it, although eventually, if you sweat a lot, it just comes loose from your body.

I wouldn't wear it while lost in the desert, perhaps, but to date, I have never had even a minor amount of discomfort, even when I had substances in my body (like alcohol) that can raise your body temperature.
