Setting powder is a lightweight cosmetic product used to help makeup last longer and reduce shine. Typically applied after foundation and concealer, it helps to absorb excess oil and create a smooth finish on the skin. Setting powders come in various formulations, including translucent and tinted options, catering to different skin tones and types. To use setting powder, a makeup brush or sponge is often employed to dust the product over the face, focusing on areas prone to oiliness, such as the forehead and nose. Popular brands include Laura Mercier, RCMA, and Maybelline, each offering unique textures and finishes to suit individual preferences.
