Foundations even out the skin and soften blemishes, but they don't always give the illumination that our face needs. They usually have a matte or satiny finish so you may need another product to sort of finish off your face in a literal halo of light. Illuminators do this for you by having light-reflecting ingredients that create this subtle haze of light around your skin.
Sounds too complicated? It's actually easy to get illuminated! It's only difficult when you're using the wrong product - by wrong I mean too shimmery, too pigmented, too obvious. I love the Guerlain Meteorites for that instant ethereal glow but for a warmer finish, I prefer to use the Bobbi Brown Shimmer Brick Compact in Bronze (P2,300).
Shimmer bomb? As the name suggests, the Bobbi Brown Shimmer Brick is shimmery in the pan. However, when it goes on your face, the fine shimmer diffuses and isn't really detectable unless you look closely. It's more shimmery than the Guerlain Meteories (which is more on the pearly side) but less pigmented than the NARS Laguna Bronzer.
Pigmentation and finish. At first, I was trying to get it to work like a bronzer by contouring my cheeks and the sides of my face with it.
