Martha Stewart's latest glam moment proves the magic is often in the final step. The product behind her smooth, airbrushed finish? The Charlotte Tilbury Airbrush Flawless Setting Spray, a cult-favorite mist that's become a go-to for locking in makeup while keeping skin looking fresh, not flat. Makeup artist Alex Rutkovskiy spritzed the setting spray on Stewart at the 5th annual King's Trust Gala in NYC, where her makeup looked seamlessly blended, softly diffused and camera-ready from every angle.
