Cosmetic powders are fine, dry products used in makeup to enhance the appearance of the skin. They can help to set foundation, control shine, and provide a smooth finish. Common types include setting powder, loose powder, and pressed powder, each serving different purposes in a makeup routine. These powders often contain ingredients like talc, silica, or mica, which help absorb oil and create a matte look. Some cosmetic powders also include pigments for added color, such as blush or bronzer. They are typically applied with a brush or puff for even distribution on the skin.
