Take a pea-sized amount of the foundation and apply a light layer all over the face using a beauty sponge or your fingers. If you need more coverage, you can apply a second thin layer of foundation. Be careful not to use too much product or put on too many layers, as it may lead to a cakey look. To finish, you can set your foundation with powder and proceed to add other elements like blush and highlighter over the base you have created.
