Through a YouTube video I do not use the roll-on in the usual way. At first I was thinking, that's nonsense, but then yet tried it once. I use the Garnier Hautklar Roll-On as Foundation. Only I distribute a small amount on the cheek, and shut the whole then with a foundation brush, then I work my way to the next cheek, chin, forehead and nose. One should not the whole face at once "berollen" as the cream dries quickly but. I must say that I've never had a foundation that has been my skin tone adapted so well and so looks natural. I start by far to not be so quick to shine as with normal Foundations. It is also perfectly suitable as a concealer under the eyes and can be set up nicely.
