The cosmetic product used to create a dewy glow on the skin is called highlighter.
Highlighter is a light-reflecting makeup product applied to areas such as the cheekbones, brow bones, bridge of the nose, or cupid’s bow. By catching light, it makes selected features appear brighter and can create the impression of greater dimension. Highlighter is sold as powder, cream, liquid, stick, gloss, solid, or jelly, and shades range from white and champagne to pink, blue, and multicolored finishes.
Highlighter has roots in stage and film makeup, where artists used reflective products to define facial structure under artificial lighting. It later became a mainstream consumer product, particularly as contouring and “strobing” trends spread through beauty tutorials and social media. MAC Cosmetics’ Strobe Cream is often credited as the first highlighter product marketed commercially to consumers.
Highlighter is sometimes confused with illuminator, although the terms can overlap in everyday use. Blush adds color to the cheeks, bronzer generally adds warmth or a sun-kissed tone, and setting spray helps makeup last rather than primarily reflecting light.
