Mehron Paradise paint, skin issues and blending?

So I'm going to be painting my entire face, neck, and arms in light gray paint. However, I'm kind of confused on what brand I should get. I don't have real dry or scabby arms or anything, but the skin on my face gets oily very quickly. i have to use 10% Benzoyl Peroxide cream on my face in the morning to keep my skin balanced throughout the day. I heard Ben Nye is pretty thick, and can clog up your pores. I looked into Snarazoo ( sorry if I spelled that wrong ), but from the pictures I've seen of people using it, it looks like it sets on your wrinkles pretty badly. So, I'm now leaning towards Mehron, especially since it's water activated ( and I'm assuming a lot easier on skin than Ben Nye ). I've never actually used any facial or body paints before, and I don't even wear make up, so I'm pretty clueless in all honesty here.

If I do go with Mehron though, I have no idea how to blend it. I'd have to blend storm cloud with white, that's all I know.
