the mac Micro refinisher is a great idea in concept, and it does exfoliate well... but I personally don't like it.
The exfoliating "grains" are perfect in and of themselves and they don't irritate, but I don't like the feel of the "cream" the exfoliant has as the base of the product.. it leaves your skin feeling like there's a film on it and I always have to use a cleanser afterwards to remove that feeling (do you know what I mean?).
You only need to use a tiny bit which is good, but for the price, I want my skin to feel clean, smooth and comfortable... which this product lacks because of that filmy feeling. If they reformulated it, I would purchase it again but not the way it is now.
I haven't tried the charged waters, but I love Fix+; I also use Evian spray water when I don't need the moisturization that the fix+ gives.
HTH!
