Although the Météorites vary amongst themselves with the specific colors in the canister or compact, having been formulated to create subtle corrective changes, I personally see the most noticeable effects in terms of what they're designed to do when I apply them over a setting powder or directly over a powder foundation. The matteness immediately softens & becomes luminous but not shiny. I experimented with them a bit, putting them directly over foundation without a setting powder and within a couple of hours I was pretty shiny, probably because they are NOT a setting powder. I would have to say that the NARS Light Reflecting loose powder, used in the same way as the Météorites was a bit more dramatic----in a good way. Although the NARS Light Reflecting powder is a "setting" powder, I prefer to use my regular setting powder and lightly dust the NLRLP over my face just as I would any other beauty/finishing powder. I also use the Hourglass 'Radiant Light' Ambient Lighting powder which also gives the same appearance of smoothness, radiance & luminosity. My personal experience is that the effects of all of these products are very similar.
