By dividing the face into sections, we will be able to spot any unbalanced proportions and will then be able to correct them or conceal them through makeup application.

By using a foundation cream or lotion that is darker or lighter than the skin color, we can produce highlights and shadows that create optical illusions. In the eye area, eye shadow can be used to achieve the same effects. Shadows are created by the use of darker colors.
