Use a flat brush to apply color corrector underneath your eyes. Using the same flat brush, apply the color corrector around your mouth and nose to brighten up your skin in these normally darker areas. Blend the initial color corrector by patting with your fingertips before applying the next layer. Next, use a foundation that matches your skin tone and apply with the same brush on the apples of your cheeks, your chin, around your nose area, and blend into your neck area. Mix a lighter foundation with the one that matches your skin tone and apply underneath your eye and around your chin. Then apply another layer of color corrector in the darker areas of your face. Pat with fingertips to blend. Using a powder brush, apply powder all over your face. Make sure to apply more powder underneath the eyelids and around the nose.
