Eyeshadow is a cosmetic product applied to the eyelids to enhance or alter their color and 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 brushes or applicators to blend the product onto the eyelids. It can be layered for intensity and combined with other makeup products, such as eyeliner and mascara, to complete the eye makeup look. Proper application techniques can help achieve desired effects and enhance the overall appearance.
