So I paid by $59.00 to try the Armani make-up (over twice the price of Fresh-Air's humble $24.50 price tag). The result: it looked fairly good, and it was different. Very light, but there was coverage unlike most "light" make-ups. However, after wearing it for about 5 hours one day, I happened to look in the mirror while I was wearing my reading glasses and noticed that I had a bit of flaking near one side of my nose and a rather dry looking patch on the other side. I no longer had that refreshed look of well-moisturized skin, but rather skin that said, "I've been on the overnight from Heathrow to Dulles and my skin feels it!"
I washed off the Armani and put the Estee Lauder back on. It looked wonderful; the color was richer, but matched my skin, and it gave me a half-dewy, half-matte look that requires no powder. I've been checking everyday since with my reading glasses to see if the look is lasting after 5 hours, after 10 hours... and it is!
If Estee Lauder ever gets rid of Fresh-Air, I may have to use the Armani, but until then, the winner is - Estee Lauder's Fresh-Air make-up base. Never fool with a winner!!
P.S. You can find Fresh-Air make-up in the standard department stores that sell Estee Lauder, but they don't seem to stock a lot of it. I usually buy it directly from the Estee Lauder website.
