Mixing face powder on this soppy mess, is, well…messy. And orange-y streaks of wet powder? Yes, very pretty.
Instead of globbing powder onto your oily face, a better tactic is oil blotting papers, or if the manufacturer prefers to talk fancy, matte blotting film or blotting linens. Essentially they are very thin squares of paper that you use to literally blot up the oil on your face, and you can see the results in all the gross wet spots on the paper.
They’re not as cute as a glitzy powder compact, but they take up less space in your purse and certainly work better than powdering over oil slicks. Some product descriptions claim they will leave your face shine-free and matte; not likely, but certainly with far less shine than before blotting.
