What is hydroquinone primarily used for in aesthetics?

Hydroquinone is primarily used in aesthetics as a topical bleaching agent. It works by inhibiting the enzyme tyrosinase, which is essential in the production of melanin, the pigment responsible for skin color. This makes hydroquinone particularly effective for treating conditions associated with hyperpigmentation, such as melasma, age spots, and post-inflammatory hyperpigmentation.

The effectiveness of hydroquinone in lightening skin tone and evening out complexion has made it a popular choice for both dermatologists and medical aestheticians. While it may be used alongside other treatments, its primary function remains that of a bleaching agent, distinguishing it from other options listed, which serve entirely different purposes in skin care.
