Blush.

"I did use a Flower Knows blush a long time ago that I didn't like. It was a blue blush that went into color, and I thought that would be nice to put, like, a little bit of blue under the eye, a little bit there, because blue is kind of brightening on the skin, right? Couldn't see it. Couldn't see a single thing."

"I wanted to take a look at this blush from a brand, Flower Knows. It has this really cute blue into a light pink. What I find really fascinating about this bluey, kind of like verging on a light lilac as it goes in, is how brightening this will be in terms of color theory, how it's going to brighten up this area. So let's try it. I want to try sweeping it this way and trying to keep that blue tone up here with the blush underneath just to see if it will brighten my under eyes a little bit. I don't know if you can see the blue on the top there and the pink. To be honest, even the color itself isn't that obvious. Let's just do a whole mix and swivel up the whole thing. There's nothing there. Okay, perhaps not the best blush, to be honest with you. It's very natural, and I think maybe if you have fairer skin than me, it would look quite nice."
