I have a ruddy uneven skin tone - and am generally fair. I also tend to get pretty oily in the t-zone. I switched to Bare Minerals about 4 mos ago and use smashbox primer underneath. I can't believe I didn't try this years ago! I finally have the flawless coverage, that I honestly thought I wouldn't ever achieve with my ruddiness!
I have combo skin and I use Prescriptives custom foundation which I adore since I totally customize it to my skin color and needs. I also swear by Lancome's dual finish powder which I've used for over 20 years. No matter what other powder I try, I always come back to this.
i have oily skin with some random dry patches. my skin is also generally pretty clear and only sometimes looks uneven/splotchy so i wear foundation only during those times or when i'm not running late (rare) .
that being said, i use Makeup Forever face&body foundation. Very nice!! very even, flawless look, with a great feel. does not make me oily, and it's easy to apply. plus it's waterproof so the lasting power is great.
it seems a bit light for the summer months recently though, so i just bought smashbox tinted moisterizer. So far so good.
i, like frosty, usually use just tinted moisturizer (laura mercier's is the BEST!) because it leaves my skin with a healthy, natural look. i take good care of my skin so i don't usually need a lot of makeup.
HOWEVER, when i really want dewy, satin-doll skin, my hg is definitely chanel's vitalumiere. it's a liquid foundation that isn't too heavy and leaves me looking flawless! it's pretty pricey, though, but like i said, i don't use it most of the time. =]
