I don't think Stila Illuminating Powder Foundation is a good choice for people who have combination/oily skin
my favorite powder foundation was Diorskin Compact, absolutely amazing for my dry skin, sheer and natual (I don't need much of a coverage anyway), very fine and non-drying, never looks heavy/powdery/chalky, gives a slightly luminous finish.
however, my skin is getting more and more of a combination type somehow
while Diorskin Compact is still great for my cheek areas, it's not good for my T-zone anymore
wears off too easily around T-zone and totally doesn't control shine.
so I went searching for the perfect compact for combination skin. after trying out lots, I've finally found my new HG powder foundation,
Guerlain Divinora Teint Expert Confort Exquisitely Fine Powder Foundation Compact SPF15
the same
superb quality and
ultra fine powder as Diorskin, goes on extremely smooth and blends beautifully with the skin. it's also got some ingredients for great oil control at T-zone, without making the cheeks feel dry. the staying power is also spectacular. it has this slight illuminating effect, giving the complexion a subtle soft glow, but overall more on the matt side comparing to Diorskin. definitely not dead flat matt though
*cough cough Chanel Double Perfection Compact
it provides medium to full coverage, fuller coverage than Diorskin but also a bit heavier. coverage is not what I'm seeking so I'm always very light handed when applying.
