I tried this foundation on my hand. The MA suggested 20, which I think is actually a good match since 20 looks very pale. It had the pleasant Les Beiges powder scent and it felt very light-weight on, almost like nothing, unless perhaps if I had applied heavily. I have an old Guerlain loose bronzer that comes in the same packaging, with a net-like sieve that allows the powder to come through. It is expensive! It is $100 here, which is the same as the pricey highlighters with intricate prints. The MA said we could apply liquid foundation first and then this. The brush is very soft and the hairs are like the retractable kabuki, but it is not retractable here. I'm not sure about how I would use or need this powder. Anna Sui has recently released a remade loose powder foundation too in a pretty dome-like packaging (to keep the brush), but bulky, and less expensive. It has a nice rose scent and on my hand it was very smooth and glowy. If I want a loose foundation I will have to examine both more closely. I tried BareMinerals loose foundation as Sephora gave me a sample, and it had a strange sheen on me and I didn't like the feeling on as well.
Here's the Anna Sui powder for anyone interested, it's the first one in the page.
