Strangely enough, super glue has always helped me in this situation... it's got this chemical in it that numbs skin, so if you rub some on your face it should take the itchiness away... It always did for me at least. Go try it. : )
Definitely try the super glue thing. My cousins live in Montana or something and they have a ton of poison ivy and always suggest doing that or something.
Superglue, that's what I was doing wrong... I just let it go last time I had it because I couldn't find any cure for it. But yeah, I've heard of that before.
