e.l.f. Poreless Putty Primer in Universal Sheer is a silicone-based, mattifying face primer with a unique putty-like texture that smooths over pores and fine lines for a soft-focus, blurred finish. Built on a dimethicone and silica base, it fills in texture and grips makeup for longer wear while keeping the base looking sheer and natural rather than heavy or cakey. The universal sheer formula adapts to skin tone, making it suitable for most complexions and skin types looking to minimize the appearance of pores before foundation. Scoop a small amount and pat evenly onto skin, focusing on areas with visible texture, then follow with foundation. A cult-favorite, budget-friendly primer known for its smoothing, poreless effect.
