Katy Perry's Met Gala skin looked incredibly smooth, glowy and camera-ready, and part of that prep came from the Loops Exfoliating Toner Pads. The Korean skincare-inspired pads are designed to gently exfoliate, hydrate and smooth texture in one step, helping makeup apply more evenly afterward. They've become especially popular among people looking for a quick way to refresh dull skin and create a softer, glowier canvas before glam. Makeup by Alexandra French broke down the look, noting that she used the pads to "prep and clean" Perry's skin to ensure there was zero dryness.
