When finishing your makeover, blend all of your makeup with a large fluff brush to ensure a natural look.
Blending your makeup is very important to show a coherent look to your makeup especially with the skin. Use your largest brush to blend all over the face. When you are brushing over your foundation and powder you can use a little bit of pressure to ensure that the powder is pressed into the foundation. Also, by using a large fluff brush you are combining all of the products and colors together; your makeup will look natural and flowing. Blending avoids lines of demarcation and combines all of your colors together to look as if everything blends as one.
