hydroquinones
Photographic developing agents
Hydroquinones are chemical compounds used primarily to lighten skin by inhibiting melanin production.
In dermatology, hydroquinone treats hyperpigmentation, age spots, and melasma: The dermatologist prescribed a cream containing hydroquinone.
The compound also serves as a photographic developer and industrial antioxidant.
Long-term use on skin is controversial due to potential side effects.
