Have you tried any of the Avene sunscreens?
I picked up the High Protection Cream SPF 20 yesterday to try. It is *very* moisturising and feels really nice on! I don't know whether I'll have a problem with breakouts or clogged pores from it yet, but I'm not getting any irritation so far and definitely don't need an additional moisturiser with it. It sinks in really well and there's absolutely no white cast.
I don't think this one is available in the US (though it is available through
www.leguidesante.com/), but there are others in the range, some with a much higher SPF and I'm guessing a higher UVA rating.
I just thought it might be a good option for your parched skin
