Guerlain De Peau is described as "foundation in such perfect osmosis with the skin that it glides on like an extremely fine silk stocking. As invisible to the eye as to the touch, it fuses with the skin like an imperceptible second skin. Impalpable and secret, this shapely, silken veil renders the complexion sublime without artifice. Its texture is so supple, so soft that it melts deliciously into the skin. Uniquely comfortable, its formulation is so light it becomes transparent. Lingerie de Peau acts in absolute, weightless affinity with the skin to infuse it with light and freshness. Sublimely transparent, the complexion becomes as soft and radiant as silk. A range of 9 natural shades, seeming to fuse so perfectly with the skin, it feels as though it were made just for you. The skin is coloured and evened out with total transparency. No colour is visible on the face; the complexion is simply fresh, radiant and disarmingly natural." (Guerlain's website)
Karla Sugar has posted some nice swatches here. The texture of this is very runny and liquidy, you wouldn't think this would give great coverage, but it really does. This feels like a second skin on, and gives an impeccably smooth, lovely finish. The best finish of any foundation I've ever used. Compared to the Lancome Teinte Idol, this stuff is much thinner. On the website, they suggest applying this with your hands, which I don't prefer, but this could definitely be applied that way, blending it down your neck is no issue either.
This foundation feels amazing on the skin, it gives medium coverage while feeling extremely light and fresh on your face. This does not cake, applies like a dream and makes your skin look stunning. It even makes your skin feel like smoother to the touch. I hope I can get this in the lighter shade, otherwise, I am going to have to pick up something else. I loved this foundation, but the colour did not match me right.
