The main difference is that a finishing powder is used to smooth things out, while a setting powder is used to make things last. So, if you’re primarily concerned with uneven texture (whether that’s from fine lines, acne scars or enlarged pores) or if you really just prefer the look of that airbrushed Instagram-filter skin, try adding a finishing powder to your routine. If you’re simply trying to get longer wear from your makeup, a setting powder can help.
Now some of you might be wondering if you can use the both of them together, and the answer is yes, in which case, you’ll want to apply the finishing powder second. (Remember: Finishing powder always goes on last.)
We’d also recommend applying the powders sparingly, making sure to tap off any excess before brushing them onto your face, and targeting where you put the setting powder (i.e., just along the oiliest parts of your face like your forehead and nose) rather than blanketing your entire face in it.
