What does the term "highlighting" specifically refer to in make-up?

Highlighting in make-up specifically refers to adding dimension by using lighter colors. This technique involves applying lighter shades to certain areas of the face, such as the cheekbones, brow bones, and the bridge of the nose, which helps to create the illusion of depth and draws attention to those features. By making these areas stand out, highlighting enhances the overall facial structure, resulting in a more dimensional and radiant appearance.

The other options focus on different aspects of make-up application. Making some areas appear less prominent relates more to contouring, which involves using darker shades to create shadows. Applying a base layer of foundation is essential for an even skin tone, but it does not pertain to highlighting. Creating a uniform skin tone also does not connect to the highlighting technique, as it refers more to the application of base or concealing products rather than the use of lighter tones to enhance and define features.
