I have this awesome green-tinted mineral stuff that I brush on whenever my face is wicked red. I was skeptical at first, but it neutralizes the redness and doesn't turn my skin green. Just a little coating does fine. I don't know if it'll help you, but it's been great for me, for both cosplay and everyday use.
