A makeup sponge is a cosmetic tool used to apply and blend makeup products, such as foundation, concealer, and blush. Typically made from soft, porous materials, these sponges can be used dry or dampened with water to achieve different finishes. The unique shape of a makeup sponge allows for easy access to hard-to-reach areas of the face, providing a smooth and even application. Makeup sponges come in various shapes and sizes, with the most popular being the Beauty Blender. This iconic sponge is known for its egg-like shape, which helps to create a flawless complexion. Regular cleaning and proper care of makeup sponges are essential to maintain hygiene and ensure optimal performance.
