What is t zone highlight?

T-zone highlight refers to a highlighting technique that focuses on the "T-zone" of the face, which includes the forehead, nose, and chin. This area is often highlighted to enhance the natural contours and bring attention to the center of the face, creating a radiant and fresh appearance. The technique can involve using highlighter products to add luminosity, helping to define features while balancing out the rest of the makeup. It's commonly used in both everyday and glam makeup looks.
