Eyelid cosmetic is a type of makeup used to enhance the eyes. It includes two main products: KOHL, which is a dark powder or cream applied to the eyelids, and LINER, which is a thin line of color applied along the lash line. KOHL is often used to create a smoky eye look, while LINER is used to define the eyes and make them appear larger. Both products can be used to create dramatic looks or subtle enhancements.
