Yves Saint Laurent Beauty (YSL Beauty) has taken a bold leap in the digital beauty revolution, unveiling an AI-powered upgrade to its acclaimed Rouge Sur Mesure Custom Lip Color Creator, a connected device that allows users to blend thousands of bespoke lipstick shades on demand.
Developed in partnership with L’Oréal’s Technology Incubator, the handheld device uses proprietary Perso technology originally revealed at CES 2020. The innovation combines artistry and AI, enabling beauty lovers to create personalized YSL Velvet Cream Matte lip colors that precisely match their wardrobe, mood, or skin tone.
Intelligence Meets Artistry
The Rouge Sur Mesure operates through four primary pigment cartridge sets—reds, nudes, oranges, and pinks—each capable of generating over 1,300 custom blends, resulting in thousands of unique colors. Users simply select a tone via the companion app, which applies AI to preview shades virtually, analyze colors from photos or real-life objects, and generate the perfect pigment mix.
Connected Beauty: The App Experience
The companion app expands the personalization journey through key features:
-
Shade Wheel – explore and visualize virtual colors instantly.
-
Shade Match – scan any real-world color to reproduce it as a lipstick shade.
-
Shade Stylist – AI analyzes outfit tones to suggest harmonious or contrasting lip colors.
-
Discovery Page – browse trending seasonal shades and community-created looks.
With a retractable mixing brush and sleek portable design, users can dispense and apply their custom blend effortlessly.
Inclusive Tech Meets Global Rollout
The device retails for $299 USD and has rolled out across the U.S., France, U.K., China, and most recently, South Korea, where the debut underscored YSL Beauty’s commitment to inclusive AI beauty innovation. Future updates are expected to expand pigment libraries and deepen AI shade intelligence through continuous app upgrades.
YSL Beauty’s Rouge Sur Mesure is redefining modern beauty rituals, making the dream of endless, tailor‑made lipstick shades an everyday reality.
