Eyeshadow is a cosmetic product applied to the eyelids to enhance their appearance. It comes in various forms, including powder, cream, and pencil, and is available in a wide range of colors and finishes, such as matte, shimmer, and metallic. Eyeshadow can be used to create different looks, from subtle and natural to bold and dramatic. To apply eyeshadow, users typically use a brush or their fingers to blend the product onto the eyelids. It can be layered for more intensity and is often paired with other makeup products like eyeliner and mascara to complete the eye makeup look.
