Wet the sponges before use, you can either soak them in water and wring them out or mist them with The White Toner. This way the sponges will retain the amount of product needed for application. Step 2 Use the round part of the pink sponge to apply the foundation, press and dab until it blends. Step 3 Use the green sponge on the flat side for contouring, its easy application will ensure that the distribution of the product is just right. Then blend until the desired result is achieved. Step 4 Use the light-coloured sponge on the peaked side to reach areas that are more difficult to cover, such as dark circles under the eyes or the corners of the nose. It is also ideal for covering small details of the face, imperfections, etc.
