I got it two months ago and although I am using it on daily basis it is only just starting to show usage in the bottle. Packaging is beautiful (very Guerlain) but I am not too happy with it. It does give the pearly shine to your skin but apart from that it does not do much - at least not for me. I think it makes my skin more oily although it is not suppose to.
After trying and loving the meteorites perles, I was intrigued by Guerlain's line of meteorites primers. After asking around a bit, I had a few people recommend getting the pearly white version, which is an Asia exclusive as it has more shimmer than the original and gold D'or versions.
I am surprised at how much I love it. It comes in a gorgeous glass bottle with a clear liquid and white pearls. When you pump the product, the pearls get crushed and mix in with the clear liquid. It creates a beautiful shimmery sheen.
I personally wear pretty sheer-light foundations (MUFE F&B, Burberry sheer foundation) and I find I use 50% less foundation with this primer, as the primer itself acts almost as a sheer foundation/TM does, improving the clarity of my skin. By itself, my skin looks glowy (but not overly shimmery, the effect is subtle). If I'm in a hurry, I'll just wear the primer by itself, and my skin still looks radiant and clear. With a light foundation on top, the glowy effect definitely still shows through, although I wouldn't recommend this to anyone who wears full coverage foundations as you will cover up the luminosity the primer gives.
Since getting the pearly white version, I have tested out the original and prefer the pearly white slightly, it just gives more of a glow to my skin. Although it is an Asia exclusive, it's available through strawberrynet for around $65 shipped.
The primer also does help my makeup to last all day, and does seem to do a pretty good job of looking in my moisturizer.
Will definitely repurchase this, although I'm not fond of the price tag, one pump is enough for my face, and I believe the bottle should last around 6 months.
