NEW TREND ALERT
STROBING . . . essentially a more minimalist version of HAC-ing that entails strategically placing your illuminator in lieu of contouring. It requires a lot less product and saves you from having to squeegee-style scrape the makeup off your face every night.
I'm into it.
Here are a few of the top-rated illuminators out there. I've used the It Cosmetics, the NYX, and the Benefit illuminators, and I've greatly enjoyed them all, so I'm not even going to rank them, but be careful with the NYX because, since it's liquid, it's easy to over-indulge. :)
