Now see, "Tinted Moisturizer" is an unfair category because it includes a lot of tinted sunscreens that are SPF 30+ and contain at least one good moisturizing ingredient. (By "tinted," I mean a tint that's actually visible on skin, not a tint that's just meant to hide zinc oxide's white/grey cast and not be super evident on skin.) I quit liquid/cream foundation a few years ago. But I still use powder foundations to tame a sunscreen's shine or cast, or just to blur the lines between my skin tones, so I can't quickly write off the whole "Foundation" category. Plus, there are skin tints containing little (below 30) or no SPF that can count as Foundation, like Glossier Perfecting Skin Tint which I've tried a few times. 

So now I'm trying to decide what I use more often: tinted sunscreens or powder foundations. I rotate through many sunscreens all year, and most of them are not tinted. And I apply powder foundation over the super shiny or very white/grey-cast ones. The more I talk through this, I think my vote has to go to: 

Foundation. And it pains me a bit to write that. 

Sephora US doesn't sell some of my favorite powder foundations, but a very recently discovered love is SEPHORA COLLECTION MicroSmooth Baked Powder Foundation .
