Foundation is key in any makeup artists routine. Basically foundation cover up any imperfection on your face. It can come in a wide range of colors as well as the way it makes you look. Some common foundation look scan be dewey, matte, or even an airbrushed finish. A few personal favorite foundations of mine include, Tarte Amazonian Clay foundation, Loreal Infallible Pro-Glow foundation, and Too Faced Born this Way foundation. These 3 foundations all have different finishes to them and coverage as well, for example the Tarte one is a full coverage matte foundation, and the Loreal one is a light to medium coverage with a dewey/glow finish. Usually I wear a dewey foundation in the winter and a matte one in the summer!
