Sponges and makeup work well together from the start of application to the finish. Wedge-shaped and oval sponges are favorites for applying liquid and cream foundations. Flat sides of wedges are ideal for patting foundation into the skin, while the pointed and thin edges fit well in small areas around the nose and eyes. Egg-shaped varieties are becoming more popular because they can roll across the surface of skin creating a flawless foundation.
Sponges help prepare the face for more makeup and they're great for finishing applications, as well. After all creams, powders and colors are on the skin, a final pressing in with a clean cosmetic sponge will soften the edges of any layers or overlap of shades and textures, and can blend everything into a more natural looking but flawless finish.
