Use a serum, then moisturize well - nothing like a perfectly hydrated skin underneath Matchmaster. There are brightening serums and moisturizers that may work especially well (I use Rodial - the daytime moisturizer has this). If it's not enough, then definitely go for a light reflective primer on top of your moisturizer (I swear by Prep & Prime Vibrancy Eye for my under eye area without fail, although I normally don't use a face primer). One thing....if you're used to letting your moisturizer sink in really well before you apply foundation, don't. Put it on and then start putting your Matchmaster on right after - that helps a lot in toning down the matte quality and doesn't compromise the staying power on my dry skin.
I'm a big Careblend fan, but I don't use it over Matchmaster. I use Elude BP (which adds brightness but keeps the matte look, which isn't what you wanted) and I also use Magically Cool Liquid Powder, which requires a little buffing but is a really nice effect with Matchmaster - glowy, but not moist. Maybe that would be a good one to try.
