The Ctzn Cosmetics Nudiversal Lip Duo ($25) is a matte lipstick and high-shine lip gloss in one double-ended product, perfect for on-the-go touch-ups. The all-encompassing nude shade range complements various skin tones, undertones, and even lip tones. My perfect brown-toned nude is the shade 21: New York City. However, with the vast selection of shades, I can go darker for a bold darker-brown lip, pinker for a rosy hue, or warmer for a sun-kissed look or experiment with a cooler undertone. To find your nude, use its Get Matched tool.
