Hydroquinone is a chemical compound with the molecular formula C6H6O2, widely recognized for its use in skincare and photographic development. In the realm of skincare, it is a popular skin-lightening agent, helping to reduce the appearance of hyperpigmentation, dark spots, and melasma by inhibiting the production of melanin in the skin. However, it has been subject to regulatory scrutiny due to potential side effects, including skin irritation and long-term safety concerns. In the field of photography, hydroquinone is utilized as a developer agent to convert exposed silver halide crystals into photographic images. Its dual role in cosmetics and photography highlights its importance in both personal care and imaging technologies.
