Okay, so this blush isn't really magic, but it's close. pH Matchmaker by Physicians Formula ($13) senses the pH levels of your skin and adjusts its color within 60 seconds to give you the right glow. It's something about the fluorescein-based dye, and it's all very scientific sounding. Here's what I know: I have a habit of dabbing various lip products on my cheeks and calling it blush because 1. I'm lazy and 2. That works pretty well. But when I have a moment for true blush, this one hits the mark. The powder even has light-adjusting pigments so that you look the same indoors and outdoors in different brightness levels. Plus, the compact has a built-in LED light, which is like having your own Hollywood style dressing mirror on the go.
Is it magic? I don't know, but I like it.
