I wasn't really shopping for a foundation, but decided to check out this one. For reference, I have combination skin with a very oily t-zone, and a couple of acne marks/discolored spots. My skintone is light golden-beige, so I typically am a level 20 in Chanel, although with the regular Vitalumiere, I use 10-Limpide, so go figure. In MAC terms, I am about NC20'ish.
I got this in the color B10. Originally, the SA had used B20 on me, but I felt that it was a tad too dark, so I think that like the regular Vitalumiere, this shade range runs a bit darker, too.
I shake the container well and then apply with my fingertips. The texture is very, very lightweight... as the name implies, like water. You can barely feel it on your face, so be sure not to overapply, as the SA did on me. (She used more than a half-dollar's worth, and applied it with a brush, which left it streaky-looking.) I think you need a dime to nickel-sized amount for the entire face, and that would give ample coverage.
The coverage is light-to-medium. I still needed concealer on my undereye circles, as well as any scars/discolorations on my face. The finish is satin - not as luminous as original Vitalumiere.
For someone oily such as myself, I had an oily nose by lunchtime. It does, however, stay on quite well on the face and doesn't melt into weird patches or separate. I also did not experience any breakouts or anything like that. It does have a strong fresh, flowery scent, but the fragrance goes away within 30 minutes.
Overall, I am quite pleased with this, and am happy to add it to my foundation arsenal.
