Since the skin on your face is not created equal, one shade of concealer may not suffice. The NARS Duo Concealer palette features two complementary shades to suit an array of complexions. The lighter shade brings brightness to the eyes, while the darker one can be used to blend directly with skin tone. Duo Concealer is lightweight but still able to provide smooth, opaque coverage to eradicate skin redness, imperfections, and under-eye shadows.
