MAC Cremesheen Glass is a lip gloss that gives you a glass look on the lips. I love the texture of this lip gloss. Not shiny or not very glossy. Its medium but then it looks extremely classic when it is applied. This was a gift to me from my sister. She has a thing for lip glosses. She likes them more than the lipsticks. She likes the effect and also the finish of lip glosses. I also became like her eventually. I found the lip glosses to be more nice to look at and also more effective when it came to nourishment of the lips.
