This type of eyeliner typically comes in a pot or jar and is formulated with a smooth, creamy texture that glides on easily. The Revlon Gel Eyeliner in "Black" is designed to provide intense, long-lasting color and precise application. It is commonly used to create defined and smudge-proof eyeliner looks. To apply the Revlon Gel Eyeliner, you can use an eyeliner brush or an angled brush for more control and precision. Dip the brush into the gel eyeliner and remove any excess product on the rim of the pot. Then, carefully apply the eyeliner along the lash line, starting from the inner corner of the eye and working your way outward. You can create a thin line for a subtle look or build it up for a more dramatic effect.
