Whenever I use the Guerlain L'Ecrin 4 Couleurs Eyeshadow (P2,998) I never fail to get compliments. People think I did something new with my skin or wore a new, more flattering blush. They say I look less tired. At first I thought that it's everything else but this palette, but now that I think about it I mostly get those sorts of compliments whenever I have it on.
Our eyes are the first things that other people look at when they see us. It's the focus of our whole face, the main feature by which our emotional and physical status are read. If your eyes and droopy and tired then your companion will think you're tired; if they are happy and bright, then you will appear to radiate that all over your face.
My theory is that the Guerlain Les Fauves palette is like "blush" for our eyes - it brightens and freshens that particular area with rich hues of coral, copper, and darkened champagne. They are warm and flattering (on me), as you can see here!
If you're very fair then this would be more of a smoky palette on you, but if you're mid to dark Asian like me then this brings out the golden tones of the skin juuuuust right.
