NARS Cosmetics Radiant Creamy Concealer. This Cosmetics Radiant Creamy Concealer from NARS is gaining cult status amongst artists and makeup enthusiasts alike. Why? because of its long-wearing, skincare-infused formula that creates a glowing finish. The buildable concealer delivers medium to full coverage that visibly diminishes imperfections, while smoothing, brightening and blurring the skin for up to 16 hours. Available in 30 shades, the formula features light-diffusing technology to help illuminate the complexion, supported by balancing powders to improve the look of the skin tone.
