Benefit Stay Flawless 15-Hour Primer, €24.50

This primer comes in a twist-up stick, blends easily and softens the skin. The instructions say to put liquid foundation on top immediately but I found waiting 2-3 minutes prevented grimy residue. The formula performed better under liquid foundation than cream or powder. It creates a matte finish and my makeup didn’t slip for the promised 15 hours.
