The Yves Saint Laurent Rouge Sur Mesure powered by Perso is a gadget launched in partnership with L'Oreal-owned YSL Beaute to offer customized lipstick shades. The device is straightforward: pop in your color cartridges, pick a shade from the app, and apply using the included applicator. The top of the device transforms into a compact for portable color. The app can make color suggestions (AI-assisted), but you can choose from options curated by influencers or the user community. Want to perfectly match your lips to your nails? There is a function for that too.
