I don't. I would LIKE to, but I don't prioritize it very highly and I don't seem to manage to get that onto my suits (along with 70 DCI, I never seem to get that high). Which is funny because I play a necro archer with 100% poison weapons who feasts on folks without CS-proof suits. But I don't get Corpse Skinned very often and my feeling is that I can just apple out of it when I need to (though on the other side of things, my feeling is that if people apple out of my CS, I'll just recast it and see who runs out of consumables first).
