Highlighter is a face makeup product designed to add luminosity and dimension to the skin. It typically comes in cream, liquid, or powder form and is applied to high points of the face, such as the cheekbones, brow bones, and the bridge of the nose. The importance of highlighter lies in its ability to create a radiant, youthful glow, enhancing your natural features and adding a fresh, polished look to your makeup. It can transform a matte finish into a more dynamic, glowing appearance, making it a staple in many makeup routines.
