Cle de Peau 105 Serenity is a permanent eye palette that retails for $55.00 and contains 0.15 oz.
Cle de Peau 105 Serenity Eye Color Duo ($55.00 for 0.15 oz.) contains a deep, navy blue paired with a soft platinum. I loved the color combination, but the navy blue could have performed better--it was a little drier and more prone to sheering out, which could be somewhat uneven in appearance without a good primer underneath it.
The formula is supposed to have a “silky” feel, be moisturizing on the lids (though it is a powder formula), long-wearing, and have true-to-pan color. I like the effect of Cle de Peau’s eyeshadows on the lid; I think that “moisturizing” aspect of them makes them sit well on the lid as time passes, where they meld well to bare skin. I find that they can be semi-opaque to opaque, more buildable and very easy to wear as a wash of color, if desired. The eyeshadows are rose-scented, though I only just noticed the scent with the compact open but not applied.
As a FYI, Cle de Peau sells the duos as a pan-only, which is not magnetized but you could stick a magnet to it so it would adhere to most freestyle palettes, or purchase their case for $25.
