The problem: I was in line at Starbucks and the gal in front of me had a glittery body lotion on. Maybe at night it would look glistening and naughty, but in the light of day it looked cheap and kind of sad. Shimmer and glimmer is good to use, but make sure you pick formulas with very finely milled light reflectors. You want the effect to be more opal than glittery. This translates to the face, too.
The fix: Go dewy for day and shimmery at night. It's as easy as that. You want the product to catch light, not grab it by the throat and wrestle it down. A good rule of thumb for day is to focus on one area of the face to shimmer; a touch of glimmer close to the lash line or on the lip is subtle and pretty.
