Q: Where do you apply highlighter?
A: On the high points that catch light: the tops of the cheekbones, the brow bone, the inner corner of the eye, down the bridge of the nose and the cupid's bow.
Q: How do you apply highlighter?
A: Build in thin layers with a light hand. A tapered brush places it precisely on the high points; sweeping it broadly is what makes it look like shine rather than glow.
Q: Do you apply highlighter before or after foundation?
A: After. Highlighter sits on top of base makeup, otherwise you buff most of it away when you apply foundation over it.
