I'm going to chime in on how I go for a dewey look (I'm in the dry skin/getting older camp).
MSFN = I like it, but there are even better options out there now, so I honestly don't use it much anymore. It's nice, but it needs Fix+ and even then, has more of a formal, matte look.
MCLP = I'm a fan of it, but it takes a little work - you can't apply too much or it starts working against you. Needs blending and just the right amount of Fix+ to finish. I'm sorry to see it get discontinued, but there are some better things out there and more to come. It IS a really good look when you get the application down just right.
Careblend Powder = OK I love this powder - it's some of the best powder I've used. It's easy on my dry skin - never makes it feel coated or dried up. It's easy to apply - very hard to overdo it. It works over foundation and even alone - the coverage is quite nice. Better than just coverage, it's got a great subtle light reflective sheen to it, not dramatic like a highlighter, but very youthful effect. It's great for day or night. You don't need to use Fix+, since it already has a light effect and doesn't need special melding into the skin. Even great directly on bags under the eyes.
Then, there are some limited edition powders that are even nicer than Careblend, but similar. Elude beauty powder is #1 for fair skin, supremely perfect texture and effect. Forever Marilyn was more matte and formal, but also light and lovely over foundation. For darker skin tones, there are fewer beauty powders, but every now and then, there's a really good one to be grabbed and stocked up on. Careblend will really cover the same territory the best beauty powders do, though. Then there are the Extra Dimension Skin Finishes - these are shinier, but with a very natural shine, like moist, refreshed skin. They seem sheer, but actually give some decent coverage, since they reflect a multitude of sins. They keep making them better and better so they're for sure worth waiting for - the ED blushes are incredible too, for something very natural looking on top of foundation. I also love the Mineralize blushes much more than standard powder blushes, for melding with the skin, but most of them look a bit better over bare skin, instead of foundation - this works ok if you are just using foundation mostly down the center of the face and sheering it out towards the hairline.
For foundation, the new Mineralize liquid foundation is very awesome, with a gel-liquid thing that eradicates pores and skin texture issues, while looking super natural and fresh. I also love the Mineralize cream foundation in the compact - it's a little different look and feel from the liquid one, but also a little bit dewier.
Finally, instead of plain Fix+, definitely try the Mineralize Charged Water. It doesn't have glycerine like Fix+, so it's not as good for fixing eyeshadow etc. but it does have a light reflective finish that is nicer than Fix+ for the full face.
