Teresa Brown uses a make up setting spray (she uses MAC Fix+) to set make up on her models for photo shoots. Brown suggests this will work for brides or evening "Or for any event where your model or client needs to have a look that can stay perfect for several hours."
In a nutshell: "I simply apply in a criss cross shape, aboutr 6 inches from the face," says Brown. "You should not saturate the face, but simply mist the make up once you have finished application." Ready, set, go.
