Although
Bare Minerals Eye Shadows
are loose powders, they are more like traditional eye shadow. They are more opaque and are generally matte in appearance.
Glimmers
have shine/shimmer, although the shimmer can be buffed down quite a bit.
Glimpses
are a combo of eye shadows and glimmers - they are more subtle.
Liner Shadows
are intense pigments that are suitable for lining, but are also used by many in the crease area of the eye lid and also on the brows.
