Eye make-up/shadow

Whinnyhi.

I have been searching but no luck so far. I made Bear a blackbear fursuit that uses his real human eyes as the eyes. It works pretty well but the eye blackening I bought runs with his sweat straight into his eyeballs and it burns and stings and makes his eyes red. So this is not useable.

So does anybody know what to use that the sweat will not turn to stinging. And there is no way to prevent the sweating because the face mask of the head fits snugly to his face.

Any help greatly appreciated.
