Blush doesn’t nearly get the credit it deserves on a daily basis, and when we see a new innovative formula to play or drape with, we know we have to score all the deets. Recently, we’ve been seeing a lot of liquid blushes cross our desks, like the classic Giorgio Armani Fluid Sheer, but we’ve also come across new formulations of this same type of product — blush oils. Blush oils are glowy, oil-like formulas that give you a hydrated, cheeky look. We asked NYC-based makeup artist Kasey Spickard to explain the best way to apply blush oils, ahead.  What’s the Best Way to Apply Blush Oil?According to Spickard, you can apply a blush oil directly onto the face as it usually comes in a stick form, or blend it out with your fingers. You can also apply this with a brush if you prefer. Spickard recommends “swirling the product on the back of the hand and then using a flat-top, dense blending brush to tap it onto the cheeks for more control.”  Can You Apply It Over Existing Makeup?Because blush oil is so dewy (and is primarily oil-based), it’s important to be careful with what kind of makeup you apply it over. “I would never apply this over a matte or fully powdered face because it will end up looking streaky,” says Spickard. You want to make sure you’re using a foundation that has a natural or dewy finish instead, if you’re going to apply it over top. Of course, the other best way to apply blush oil is over a primed, bare face if you’re looking to achieve a more minimalist effect.
