Shimmer Brick is probably one of Bobbi Brown‘s most popular items. For holiday 2008, Bobbi Brown has released a limited-edition Copper Diamond Shimmer Brick Compact.
The five subtly different shades are packaged in a very glamorous gold case with a decent-sized mirror, although the case always seems slightly lighter than how I’d like it to be (especially when I compare it with Dior’s Night Diamond, which is smaller and thinner but a lot heavier).
The compact includes various shades of beige and light bronze. The combination of these shades is a warm beige with hints of gold that should suit most skin tones (unless you have a cool-toned fair skin tone, in which case a platinum-toned highlighter would be more complementary). When applied with a powder brush, the finish is shimmery with visible multi-colored shimmery particles. When used as eyeshadows, they can be built up to a metallic finish (with a low pigmentation level.)
I personally find this compact to be the most useful as a highlighter for cheek bones. (For me, it is almost too shimmery for the T-zone.) I use it over my powder foundation and under my (predominantly matte) loose powder. This way, the finish is more glowy than shimmery and suits me a lot better.
Apart from a face highlighter, it can be easily used as a body shimmer to add a bit of pizazz to your party looks.
