Highlighters are cosmetic products designed to add a radiant, luminous glow to the face, accentuating features like cheekbones and brow bones. Available in powder, cream, liquid, and stick forms, they use light-reflecting particles for subtle or dramatic effects. Examples include Swiss Beauty's liquid highlighter for a natural glow and Imagic's powder highlighter for a shimmering, party-ready look, each with distinct application methods and suitability for different skin types and desired finishes.
