Kosas Hotliner Retractable Lip Liner – Built-In Sharpener & Brush, Hydrating & Long-Lasting

Define with Confidence, Hydrate with Every Glide

Meet Kosas Hotliner, a Hyaluronic Acid–infused contouring lip liner designed to deliver more than color. Its silky, creamy texture glides on for precise definition, while the formula works to hydrate and visibly plump lips over time. With eight rich shades and a retractable design, Hotliner is built for everyday use—whether you’re sketching a bold lip or filling in for a fuller, softer look. A gentle, sweet fragrance adds a touch of luxury to your routine, making application feel indulgent rather than routine.

The core of Hotliner lies in its smart, all-in-one design and clean beauty credentials. The built-in sharpener keeps the tip crisp for accurate lines, and the included brush helps you blend harsh edges into a seamless finish. Infused with Hyaluronic Acid and Konjac Root, the formula aims to hydrate lips while maintaining long-lasting color from morning to evening. This is a cosmetic tool you can reach for when you want a defined lip without constant touch-ups.
