What it is: A double-ended eyeliner that's a semimatte liquid eyeliner on one side and a smooth gel eyeliner on the other for your perfect desired makeup look. What it does: Twin Liner Gel & Liquid Eyeliner delivers high-impact color and up to 16 hours of long lasting wear. Each eyeliner shade duo includes an ultrablack liquid liner paired with a color gel eyeliner. How to use: Customize your eyeliner look with Valentino's Triple Technique. For a subtle eye makeup look, apply the liquid or gel eyeliner along the top lashline, extending slightly past the outside corner of the eyes. For a signature eye look, apply the liquid eyeliner first along the top lashline, extending straight past the outside corner of your eyes. Next, apply the gel eyeliner alongside the liquid liner to create a double twin line. For a statement look, apply both the liquid and gel liner side by side in the crease of the eye. Made in France
