'化妆' (huà zhuāng) is a verb meaning 'to apply makeup' — the act of using cosmetics to enhance or alter one's facial appearance. The first character, 化 (huà), literally means 'to change' or 'to transform', while 妆 (zhuāng) means 'makeup' or 'adornment'. Together, they convey the idea of transforming one’s appearance through cosmetic application. It’s commonly used in daily life — for personal grooming, special occasions like weddings or performances, or professional contexts such as modeling and theater.

This word functions as a separable verb: the object (e.g., 眼影 'eyeshadow', 口红 'lipstick') often appears between 化 and 妆, as in '化个淡妆' (apply light makeup). It can also appear in compound forms like 化妆品 (cosmetics) or 化妆师 (makeup artist). Unlike English 'make up', it is not used reflexively — you say '她正在化妆' (She is applying makeup), not 'she is making up herself'.
