Cosmetic powders are fine, dry formulations used in makeup to enhance the skin's appearance. They can serve various purposes, such as setting foundation, controlling shine, or adding color. Common types include setting powders, translucent powders, and blush powders, each designed for specific effects. These powders are typically made from ingredients like talc, mica, or silica, which help absorb oil and provide a smooth finish. They come in various shades to match different skin tones and can be applied with brushes or sponges. Proper application can help achieve a flawless look while allowing the skin to breathe.
