I'm not a girl that likes to touch up makeup throughout the day. I need long-wearing eyeliner and mascara that won't smudge. But since my skin has been so dry lately and foundation looks like a mess over it, I've been wearing sunscreen and I have to reapply that every so often- and since I'm not wearing anything for oil control, I've thrown a mattifying powder in my backpack the past week and I'm surprised I've never done this before.
I got Urban Decay's de-slick mattifying powder when it went on clearance to make room for an updated formula or something, but this old version works wonderfully. I use a large flat-top powder brush (the one that came with the Sephora radiant orchid brush set) and swirl it around, then lightly dust it over my cheeks, nose and chin. My forehead is thankfully covered by my bangs, so although it is shiny most of the time because of that, you can't see it.
I also love this Guerlain KissKiss gloss for a simple everyday color. It's pale pink and shimmery-sparkly, but just enough of each to give you a little color and depth. This gloss is pretty opaque but since it's such a natural looking shade on me I don't have any problems with patchiness or obvious smearing. The one complaint I do have is the smell--- I enjoy violets, yes, but this is so heavily fragranced that you can smell it as soon as you open the tube and it hangs around for most of the wear time. The scent on the Rouge Gs has nowhere near this kind of lasting power. Still, it's not an offensive scent. This formula feels so divine, not sticky at all but plush and squishy, and has impressive wear time for something this un-sticky. I hate sticky lip gloss. If I want more lasting power out of a lip color I'll just go with a lipstick or a lip stain, there's no reason to use a gross lip gloss for lasting color.
I also carry a lip balm with me everywhere. I have one attached to my keychain, I have Benebalm in my purse, and a Burt's Bees in my backpack. Lip balm is essential. More practical for class than pulling out a luxurious lip gloss, too. Fewer weird stares.
