OK - before your cringe, let me explain.  I'm not talking about the huge chunks of glitter we all thought looked so good in junior high.  I'm talking about 'microfine' shimmer that looks soft, not discoball-esque.  Shimmer is a great tool to give your face a glow and adds dimension.  I highly recommend using it after a really long night.  You'll never hear the phrase, "You look tired!" again! 
   In order to prevent a junior-high repeat, you need to apply shimmer strategically.  Great places I like to apply it are the brow bone, inner corners of the eyes, the tops of your cheekbones, and the collarbone.  Apply with a light hand, and you'll avoid the trip down memory lane to the place where acne was prevalent and beauty was scarce.
    There are a couple of different formulas you could choose for your shimmer, including powder or cream.  Some of the powder formulas come in this nifty package with a brush, and the shimmer is in the handle.  Those are perfect if you have a few extra minutes.  I personally like cream formulas in a tube because they're quicker to apply and last a little longer.  Plus, they're great to travel with.  Choose any formula in a neutral shade.  I recommend a pale pink, cream, or skin-colored shimmer.  Avoid anything that looks like it belongs to a clown, and you'll be looking gorgeous!
