I love this so much it makes me want to cry. I think it's the same thing that's being reviewed here: Perfect White Whitening Brightening Protective fluid, spf 40 etc, something like that.
It's not very moisturising but that's OK, I only use it in summer when my skin doesn't need much moisture. It makes my skin look bright, matt and even-toned as soon as I apply it, it's a decent base for foundation, not sticky and it's got high sun protection from both UVA and UVB rays. Sometimes I skip foundation after this because it makes my skin look so even (if a bit pale).
The sun protection and whitening are good too: I came back home after a day in the sun and my tiny freckles which come out in the sun had disappeared. It's also made quite a big difference to the two post-acne marks I have.
Only problem is it's hard to find as not all Guerlain counters have it. But I don't care - I'll hunt all over the world for it if need be!

Nice pink sun protection fluid. I actually use it as a primer as it cancel out my yellowish undetones. I don't think it is a good moisturizer but I don't expect a sun protector to be so. Its best quality is that it doesn't cause breakouts on me as do all sun protectors I have tested so far.
Sadly, it is discontinued and has been replaced by the Issima White C daycare which is beige.

best skin care product ever.. it acts as a moisturiser,sunblock and instantly evens out and brightens your complexion. A must buy for everyone! Can be used alone or as a make up base..small amount goes a long way! Lovely smell too!
