I bought this once and used the whole tube but was looking forward to it running out and going back to my usual Chanel Vitalumiere Aqua (shade B10, which is perhaps slightly pale for me). I had this in no. 3 Cream Beige and for some reason the first time I had it, I wasn't so keen. It was lighter coverage than I'd hoped, and I found it made me too shiny, rather than dewy, and definitely not velvety/powdery as other reviewers have commented. The colour match was great, however, and it feels lovely on the face, not heavy at all and kind of smooth?
ANYWAY, for some reason I was still searching for my perfect foundation (even though there was nothing really wrong with Chanel one) and a year later I decided to try this one again - whenever I looked at photos from the time I was using this my skin looked great. The first time round, it was the moisturiser (Embyrollisse) I was using was that was contributing to the shine I wasn't keen on, and I had the wrong shade of concealer at the time also. (Moved from NARS Radiant Creamy Concealer from Chantilly (too white/ashy) to Vanilla).
Basically, with a bit of good concealer and good moisturiser this really is a beautiful foundation. I really want to try it with a blurring/longevity improving primer too (thinking of the YSL one) as I think it could look literally flawless. Saying that, one of the best things about this foundation is the way it sort of melts off/into the skin-- it doesnt separate or group or oxidise, it elegantly fades!
I think it is kind of comparable to Charlotte Tilbury's Light Wonder, but this is less full on shiny, wears for longer, and has slightly more coverage -- to me a slightly more refined version.
TL; DR: This is a beautiful foundation, I would describe the finish as satin-y/ dewy, with a light to medium coverage. Also, I really have not noticed the smell other reviewers have mentioned!
