Although each formulation of blurring primer will differ, the basic gist of the product is to help “fill in” any kind of unevenness—this includes both pores and fine lines—thus helping to create a smoother look.

For example, if you’re oily and acne-prone, opt for a lightweight, water-based primer with non-comedogenic and blemish-fighting ingredients like Pixi Flawless & Poreless Primer. Conversely, if you’re dry or combination skinned, adding a blurring primer with hydrating and moisturizing benefits to your routine—like Charlotte Tilbury WONDERGLOW Instant Soft-Focus Beauty Flash—can help up those essential moisture levels while imparting its pore-minimizing magic.
