Mequinol is an organic compound derived from phenol, where a methoxy group (-OCH₃) is attached to the benzene ring. It is often used in the treatment of hyperpigmentation (such as in the case of age spots or sun spots) and is considered a skin-lightening agent. It has antioxidant properties and can also be used as a reducing agent in certain chemical applications.
