I had been looking for years for a foundation that stayed matte all day and wouldn't slide off . . . and I found it! Yay! Revlon ColorStay may be my Holy Grail (I'll have to wear it a few more times to be sure) because it keeps my oil-prone skin matte through a whole day working frozen foods at my local super Wal-Mart (read: hard physical labor), it sets to my skin quickly and I don't have to use powder or blotting papers, it feels light enough so my face feels naked but it covers well enough to hide cystic acne scars without looking cakey, it doesn't settle into my pores or move around on my face and every time I look in the mirror it really does look like I just applied it. I sweat at my job and even that doesn't phase this foundation. The bottle is a little aqward, and it's more expensive than most drugstore brands, and I do have to work fast to blend and I spend more time removing it at the end of the day than with other foundations, but those are merely minor, minor drawbacks which won't keep me from using it or from buying this makeup again. I am quite pleased with it overall. I wish I had tried it years ago! Update 02/18/04: The wide-necked bottle isn't a problem when I use a makeup sponge rather than my fingers. Sponges are more sanitary and you avoid getting oils in the makeup from your fingers, so I always use a sponge now. Applies and blends better with sponge, too. Am truly amazed at the staying power of this foundation. This is on my permanent Holy Grail list as the best heavy-duty coverage foundation with serious staying power & anti-shine properties.
