In response to annonymous's problem of grey olive skin in winter, I have used for many years Clarins Beauty Flash Balm (Eclat de Beaute) every morning over moisturiser. It is a lovely peachy colour in the tube and a very light application gives a dewy glow as if you've just come in from a blowy walk along the seashore. It suits my Anglo Italian complexion perfectly and avoids any need for foundation or powder, thus allowing the scrubbed French look you mention. I'm sure you will not be disappointed.
I find these comments baffling. I have tried Beauty Flash Balm and have never noticed a blind bit of difference, whether under or foundation, or without it. As for it obviating the need for foundation, ha! I am convinced that this must work for some types of skin, but not others, because I have repeatedly had this conversation with the many members of the League of the Beauty Flash Balm Mystified.
