Step 3: Powder

After you apply the foundation and concealer, dust a light layer of powder over the entire face and eyelids. Apply the powder with a large, full, round brush. Avoid using a sponge or powder puff, which can put too much powder onto the face. Pick up some of the powder on the full end of the brush, knock off the excess, and brush it on using the same motion and direction as you did for the foundation (down and out).
Powder is great for touch-ups as the day goes by to dust down excessive shine.
Powder with sunscreen must be applied liberally so a thorough application is necessary for adequate protection. It is best to use a powder with sunscreen in combination with a foundation and/or moisturizer that also offers sun protection.
