Ever since I waded into loose powder territory, I found that the boundary of their functions blurs a bit. After all, the couple of criteria I had were: 1 - it's a loose powder, and 2 - it has high-ish SPF, although I've broken this rule a couple of times already, picking up powders with meager SPF20+. My current makeup routine calls for 2 rounds of powder, the first dusting to set the bb cream I apply as concealer and highlighter around the nose/mouth area and under the eyes, and the second and last dusting as finishing touch.
