The thinnest, softest, waterproof gel liner encapsulated in a 1.5MM mechanical pencil. This liner offers precision accuracy and ease of application, requiring no pot, brush, or clean-up. Just two clicks and one stroke create dramatic definition that resists transfer for extended wear. The unique formula, housed in a slim mechanical component, provides the malleability, intensity, and staying power of a traditional gel liner. Its waterproof, transfer-proof, and long-lasting formula ensures extended wear. The precision 1.5MM tip allows for effortless control and tightlining between lashes. Each advanced mechanical pencil lasts for approximately 17 to 20 uses. It is ophthalmologist tested, vegan, and cruelty-free. Hourglass developed this formula to prime skin and create the perfect canvas for the Ambient Lighting Collection. The first-of-its-kind formula creates the thinnest layer of light-enhancing particles, allowing for layering without re-emulsifying the underlying layer, resulting in a weightless lighting effect on the skin. This breakthrough primer creates an ideal base for light diffusion and refraction while prepping skin for makeup application.
