Name	Hydroquinone
Groups	approved investigational
Description	Hydroquinone is a topical lightening product found in OTC products, and is used to correct skin discoloration associated with disorders of hyperpigmentation including melasma, post-inflammatory hyperpigmention, sunspots, and freckles. It can be used alone, but is more frequently found in combination with other agents such as alpha-hydroxy acids, corticosteroids, retinoids, or sunscreen. Hydroquinone has come under scrutiny due to several complications associated with its use, including dermal irritation, exogenous onchronosis, and carginogenicity. As a result of these concerns, hydroquinone has been banned in the EU and UK.
Synonyms	Quinol p-Hydroquinone p-hydroxyphenol 1,4-benzenediol benzene-1,4-diol 1,4-dihydroxybenzene 4-Hydroxyphenol p-Benzenediol Hydroquinone
