Beauty sponges are makeup application tools designed to help achieve a smooth and even finish. Typically made from soft, porous materials, they can be used to apply products like foundation, concealer, and blush. When dampened, they expand in size, allowing for better blending and a more natural look. These sponges come in various shapes and sizes, with the most common being the teardrop shape. This design allows for precision in hard-to-reach areas, such as around the eyes and nose. Regular cleaning is essential to maintain hygiene and prolong the lifespan of the sponge.
