Formula: I seriously did not want to touch this because it's ridiculously beautiful but I managed to find an extra fluffy brush to sample it. I know. I will eventually have to dig into it but for the time being I'm just going to stare at it on my vanity table. The powder is super fine, sheer and natural looking. The glitter initially is sparkly but wears down. It adds the slightest hint of warmth to your face and a whole lot of gorgeous glow. As you use the powder, the shimmer will eventually wear down to a minimal so the glitter effect shouldn't be a problem since it's mostly concentrated on top. The compact is well made -- complete with a mirror and mini brush contained in the bottom secret compartment -- and a fabulous value for the fill weight and quality.
