iron oxide allergy?

So I have been using Bare Minerals foundation for about 4 years, and had no problem with it. Then about 4 months ago I noticed it would make my skin a little itchy when wearing it. And, after I would shower and go to bed, I would wake up with extreme itchiness on my face and swollen eyelids.

I did some research and thought it might be the bismuth oxychloride. Since then I have tried about 15 different foundations, none of which contain bismuth oxychloride. Every single one of these foundations, including several that claim to be hypo-allergenic, has given me the same reaction the morning after I use it, especially if I was sweating while wearing it.

I've carefully examined the ingredients, and discovered that all the foundations I've been trying contain both titanium dioxide and iron oxides (the latter apparently give makeup its color). I've ordered makeup that lacks the titanium dioxide, but I worry it is the iron oxides that are giving me this horrible reaction.

It is my worst nightmare not being able to wear makeup, as a I have severe rosacea and dark under-eye circles. What do you think this allergy could be? And is there makeup out there that doesn't have any iron oxides? (I've look thoroughly but found nothing). PLEASE HELP!!!!!!!!!!!!!

I've had similar issues worsening over the past few years.  Thinking back, it all seemed to start when I began using bare minerals (mild at first almost not noticeable, worsened significantly after my second baby.  Thought it might be the move from NY to NC and all the new pollens-but I've never had allergies before.  Been to the doctor, allergist and eye doctor.  Had patch testing (all negative). I've been diagnosed with contact dermatitis (cure-don't wear any makeup-not my favorite option-so I keep looking) and eczema (creams-nothing worked)  It's been four years or so now and it is so bad that I haven't worn eye make up or makeup near my eyes for over a year.  Tired Covergirl clean today near my eyes -eyes a mess again.  So I checked every label I could. Some form of metal was present in everything I have saved, but can't use - Parbens sometimes. Pure and Natural soap (The original stuff) on my face (scary enough) helped alot.  I'm going to try the 100% Pure make up line made out of fruit extracts next.  Until then, I'm make up free around the eyes.
