Easy Makeup Q&A “Finishing Powder Before or After Setting spray?” Finishing powder as the name suggests finishes your makeup, blurs and smooth and even sets the whole face. So the makeup looks very cohesive and flows smoothly. In my opinion, you can use the finishing powder before or after the setting spray. For maximum impact, I would use finishing powder after the setting spray. Let the setting spray dry 90% and then use the finishing powder. You can also use it on the go for touch ups! @fenty
