The color I have is Timeless Taupe, and I'm pretty sure it is a perfect shadow! I was skeptical, and my lifestyle is such that wearing eye shadow for 24 hours just doesn't make sense -- but I was blown away. First this color is perfect for my skin, eye and hair color. Second, it is like wearing multiple colors, with just one shade -- each and every time. When I am stretched for time, but I really want to look put together this is the product and color I've been reaching for. I put it on my lid and blend it into the crease and it looks just like I have 2-3 shades of eye shadow on! It is a lovely taupe that does have sparkle (no fallout for me) so if you are hesitant to buy a sparkle shadow this will not work for you -- but if don't mind or even like the sparkle -- it would be a bad idea to pass this shadow up. It does last quite a long time (without a primer it doesn't last 10 hours without creasing (even though it does crease minimally at that point), but with a primer it is unstoppable... Great product, highly recommended!
I bought Continuous Creme, Timeless Taupe and Extremely Espresso for a smoky eye. You can easily control the day to evening look with a brush. It lives up to its name and does not crease, even in humid weather.
The formula is fine--somewhere between a cream and a powder (not as creamy as Benefit cream). Easy to apply with your finger. It does not crease (I used it with a primer). The only drawback for me is the abundance of glitter in the color that I tried (perpetual pink). At the end of the day I was left with no color and only glitter. Not flattering on over 40 eyes in my opinion. All shades seem to have an overabundance of glitter--not shimmer but glitter.
