RMK's loose powder in shade P00 is a very pale pink shade with shimmers.
I found that this works best a highlighter. As such, I use it only in places I like to brighten. Usually, I put it under the eye area to set concealer, which performs well.
I don't recommend using this on the entire face, since it tends to be powdery, makes skin unnaturally white and shiny all over.
There are two more shades of matte loose powder in RMK's collection.
