I used Missha's BB Boomer in this FOTW (will soon update the rotation!) and I'm so in love with it. Firstly, I've never tried a BB cream, despite my Asian heritage, and I had no idea there were BB cream primers. Question: Aren't BB creams supposed to be miracle products that act on their own and need no support whatsoever? Just saying.
I also use this as a moisturizer, and holy cracker, does this make my skin feel soft. It also makes my skin look more finished, if that makes sense? I've never been one for illuminating/dewy/glowy/Twilight-sparkly foundations since I have rather combination-oily skin, but this makes me rethink all that. It covers absolutely nothing, yet I feel as though I can go bare faced with this moisturizer on. It's probably just wishful thinking.
Price: I got it for free when I purchased my BB cream. A quick Amazon search tells me you can get a 40 mL for $7 but it retails for $25.
Product: It doesn't specify an SPF on it (or maybe it does, but I can't read Korean), but people claim that it's sunblocking. I don't like to use sunscreen after because it ruins this other-worldly softness it gives my skin, but I probably should, just in case.
Availability: I got mine from a Korean grocer on Bloor, just west of Christie. It's underground and they also sell Missha Perfect Cover.
Wear: I don't use it as a primer so I can't comment
I think I'm going to put some on right now.
