Makeup sponges are soft, porous tools used for applying and blending cosmetics, such as foundation and concealer. They come in various shapes and sizes, allowing for precise application in different areas of the face. Many sponges are designed to be used wet or dry, with damp sponges providing a more natural finish. These sponges are often made from materials like latex or foam, which help to create a smooth, even layer of makeup. Popular brands include Beautyblender and Real Techniques. Regular cleaning is essential to maintain hygiene and prolong the life of the sponge.
