Makeup sponges , also called blenders , are very useful tools for achieving a perfectly even complexion. They allow liquid and creamy make-up products to be applied precisely and evenly, for flawless results . Makeup sponges are usually made from foam, latex, or silicone . Foam sponges are the most common and popular. They are soft and resistant , and allow an easy and uniform application of make-up products. Latex sponges are also soft and strong, but are best suited for people with normal to oily skin. Silicone sponges are less common but have the advantage of being hygienic and durable . Makeup sponges can come in different shapes and sizes , but the most common shape is the egg shape. This form is easy to use and makes it easy to reach all areas of the face. Some sponges have flat edges that allow makeup products to be applied to larger areas, such as the forehead or cheeks. It is important to clean makeup sponges regularly to prevent the growth of bacteria and to preserve their durability. Sponges can be cleaned with warm water and mild soap, or with a cleanser specially designed for makeup sponges.
