So this is my companion who tried it (I should have seen that it is undetectable try ;-)). She was rather surprised by the fluid texture of this product, far from the traditional foundation. Regarding its implementation, she found it quite painful to use with the rod that provides the recommended three drops. It's not very intuitive at first, even if we get the system thereafter. However, this does not prevent to marry the corners of the face (dailleurs fortunately!). In terms of the sensation provided by the texture, it is cool enough, even a little refreshing in the morning which is far from unpleasant.
Regarding the essential, namely the visual, she found a pallid strand compared to the tinted cream she usually uses. This is not so much the color itself that is problematic (it is on a 21 "golden beige," and a 30 "sand" allow an eminently darker shade!), But kept on the skin that lasts painfully a whole day ... So early in the day, the effect is nice because it hides the background complexion imperfections or pale complexion in the morning without quon realizes the use of a foundation, but late in the day, the effect has greatly diminished and no longer hides much fatigue.
In the end, this is a product that has significant advantages but still much room for improvement, especially in terms of its applicator and especially as regards the holding of the foundation on the face.
