physicials formula is great. both the liquid and the powder. every other type of make up (all non mineral) that i tried, i could only wear foundation for a couple of hours without a breakout, and powder only for a bit longer than that. and i was only matte for about 10 minutes.
with PF, i can wear the liquid almost all day without getting breakouts, and the powder doesn't make me break out even if i have it on all day. it needs to be reapplied once for me though, which isn't bad compared to other make ups i've tried.
the line is awesome. they have a whole range of stuff, all that is either all, or mostly made of minerals.
