Is this homemade face cream still good if...?

I made it with shea butter and milk, it's been sitting in the refrigerator for such a long time, probably months. If it were just milk, I know it would be bad to drink, but it's not for drinking, it's mixed with shea butter to use on your skin...Would it still be good or would it be bad to put on your skin now that it's been sitting for so long with milk in it and it's probably spoiled?
