Glossette is one of my fave lipglosses. I have been using this since late spring. At first I had mixed feelings about it, because it seemed kind of a scary silvery taupe shade going on. But the color seemed to change after a few minutes to a more peachy brownish shade. I have also experimented with it a bit and I've found that if I brush on just a real thin layer of clear lipglass before applying glossette(since the lacquers tend to be a bit dry even though they are considered glosses themselves), and also use my Iman lip pencil in espresso to line my lips (btw, Espresso is very similar to Mac's chestnut, but without the slight reddish cast). Then, I kind of blend the 'brownness' of the lipliner with the glossette to create a really pretty shade. There is no exaggerated lip line when I'm done, and the silvery shimmer of the glossette gets toned down a bit more. A perfect marriage!
I just recently started using this powder (it's been maybe a little over a week now). I have it in the color 'dark'. I have to admit that I really wasn't expecting it to work very well since my skin is ridiculously oily - especially my t-zone. But, I honestly like the way the blot powder helps make me less oily. I wear it over the select sheer powder (NC55), and brush on a little blot powder to finish it. I used to start seeing breakthrough oil within minutes of applying my makeup in the morning, but this stalls the shine off much longer. It is not a miracle powder, but I will say that I am pleased with what I have seen it do so far. =)
