Final answer:
A loose powder is applied to set the foundation and concealer, not to add color to the cheeks, enhance the eyebrows, or moisturize the skin.
Step-by-step explanation:
The reason to put a loose powder on during make-up is to set the foundation and concealer. This step helps to create a smooth finish by absorbing excess oils and preventing make-up from creasing or sliding off. It is not primarily used for adding color to the cheeks, enhancing the eyebrows, or moisturizing the skin.
Eyebrow products like shaders, pencils, and gels are specifically designed for defining and filling in the eyebrows to create a fuller appearance. Eye shadow is used to add depth, complement eye color, or draw attention to the eyes, and it comes in many forms but is not intended for setting foundation and concealer. Mascara's purpose is to darken, thicken, lengthen, and define eyelashes. While these products serve different purposes in eye make-up, loose powder is distinct in its role in setting the base make-up.
