You know how you've been looking for that one product that will wrangle your oily skin into submission? Well, it's the Murad T-Zone Pore Refining Serum (£49) you want. No matter how much powder I use, my forehead has reflective properties by noon. But this serum tones it down from oil slick to dewy glow. One pump of this gel includes glycolic and salicylic acids to help clear out pores and essential fatty acids that regulate the amount of oil produced from the start. It's so good at its job that it's replaced primer in my makeup routine. Call it an upgrade.
