So I recently started using an spf tinted moisturizer that contains only chemical sunscreens.  But I didn't want to rely on it for sun protection.  I tried my regular sunscreen under it, but the combination was too greasy.  The mineral sunscreen I have was much more mattifying, but gave me a pronounced white/gray cast that affected the color of the makeup.  So I'm exploring other options.  I tried LRP anthelios (the one I have is chemical plus titanium dioxide), and ouch, skin burn--too much chemical sunscreen layered under that tinted moisturizer!  The other issue I had with the anthelios--same as pure mineral sunscreens I've used--the titanium dioxide kind of seems to get stuck in small pores/blackheads and makes "bumps" or flaky looking patches in those areas.
I've read that zinc oxide tends to be less whitening than titanium dioxide, and depending on who you ask, zinc oxide is probably good enough for broad spectrum coverage (some will disagree).  Which is the least whitening mineral product anyone has tried?  I've looked at a lot of options.  Elta MD has some where the zinc is combined with I think octinoxate, so maybe would give me a bit less chemical burn than the anthelios when layered under my tinted moisturizer.  Becca cosmetics (the maker of my spf tinted moisturizer) makes a mineral spf primer that has only zinc as the active ingredient--kind of expensive, though.  Any other recommendations?  And do all of them have that blackhead-amplifying/ flaky effect? 
It would be good for me to find a mineral sunscreen I can use b/c I suspect the daily chemical sunscreen use may not be helping my rosacea.  But they always seem to look crazily white/grey on me, and I'm not that dark.
