Under eye concealer: Tarte Dark Circle Defense Concealer http://www.tarte.com/ - this makes me look like I've slept for at least 8 hours and I use this day and night.
Blemish Concealer: Estee Lauder Maximum Cover http://www.esteelauder.com/ this is very light in texture but it covers EVERYTHING! It's also waterproof and long lasting making it ideal for day or night.
Foundation: I use Benefit Hello Flawless Powder Foundation http://www.benefitcosmetics.com/
during the day I use this powder to even out my skintone and provide more sun protection whilst still looking natural. For evening I use Hourglass Fluid Veil http://www.hourglasscosmetics.com/ for its smoothing and tightening effect and use Givenchy Parure Powder Foundation for touch ups throughout the night http://www.parfumsgivenchy.com/ it gives a radiant glow that doesn't look at all heavy.
Loose Powder: I always use loose powder after a liquid base as not only does it help to combat shine but also gives an airbrushed effect. I love Jurlique Citrus Silk Finishing Powder http://www.jurlique.com/ which is perfect for my oily skin. I wear this without any makeup sometimes just to eliminate shine and even out my skintone. There are other variations to suit all skin types in the range.
Blusher: I use both a cream and a powder blush depending on the time of day, usually just cream during the day but both layered in the evening. My favorite creme blush is Face Stockholm Creme Blush in Rio http://www.facestockholm.com/ it's a bright pink in the palette but is a beautiful sheer pink on that gives a realistic pink flush, perfect for day. At night I like to top it (after powder) with Cargo Powder Blusher in Catalina http://www.cargocosmetics.com/ a tropical looking pinky coral (it's Terri Seymour's favorite too
