Extended 24+ Hour Wear: Provides steadfast color on the eyelids that resists fading or flaking from morning to night. Waterline-Approved 12 Hour Performance: A highly effective smudge-proof eyeliner for waterline application, offering intense definition that stays in place for up to 12 hours. Effortless Gel Glide: Formulated with Pigment Alchemy, the pencil moves like a liquid liner for a seamless, tug-free application. Waterproof and Transfer-Proof Finish: Features advanced Line-Lock Technology to create a resilient finish that withstands moisture, humidity, and rubbing. Ophthalmologist-Tested for Safety: Deemed suitable for use by contact lens wearers and those with sensitive eyes, ensuring comfort without irritation. Consistent High-Payoff Color: Praised in many a MAC 24 hour wear gel eyeliner pencil review for its single-swipe color intensity, eliminating the need for multiple layers. Suggested Use For precise definition, apply the pencil directly along the upper and lower lash lines. For a softer, smokier appearance, gently smudge the line with a brush or fingertip immediately after application before the color sets. The pencil can also be applied to the waterline for intensified eye definition.
