I am a fan of Meteorites, and have them in the Loose Balls form (all 3 colours), Voyage compact in Mythic, Travel Touch in Mythic and Poudre de Perles in Beige.
So here's what the salesgirl at the counter told me about the different types of shades and levels of shimmer in the different ranges.
In ascending order of shimmer:
1. Voyage compact in Mythic (least shimmer, almost matt)
2. Poudre de Perles or Illumintating Pressed Powder
3. Loose Balls & Travel Touch (both have the same level of shimmer)
4. Radiant Butterfly (highest shimmer)
Well, I think she's spot on!
In terms of colours, the numbers on both Loose Balls and Poudre de Perles correspond and are similar, but not exactly the same. That means Loose Balls #1 is similar to Poudre de Perles #1 and so on so forth.
#1 for both gives a brightening look.
#2 gives a freshening effect
#3 is more a natural skin tone effect. Apparently, #3 for Poudre de Perles is more shimmery than #1 in the same range.
Anyway, I love all of my Meteorites, save for the Radiant Butterfly LE range that I didn't buy, as I felt it was too sparkly and more suitable for nights out than every day use.
When I'm fair, I can choose to use Mythic (Loose Balls/Travel Touch/Voyage Compact) as a base, as well as for touch ups during the day.
When I'm tan, I use Poudre de Perles in #3 (beige) as my base, and then maybe a little sprinkling of Mythic as a highlighter.
Loose Balls in #2, the pink colour, I use as a blusher.
Anyway, they're perfect for all situations!
I have good skin, so Meteorites really works for me, so I can't say very much about whether they cover imperfections. But they impart a glow on my face, giving it that soft candlelit effect that everyone's writing about.
I do feel that the Loose Balls provide less coverage than the pressed powder versions though.
Hope this helps, and doesn't confuse you girls even more!
