Hydroquinone

Hydroquinone is a local cream prescribed for dark or hyper-pigmented skin marks such as freckles (small flat brown marks on the face and sun ‍‍‍‍‍‍​​​‍​​​​​​exposed areas), melasma (brown patches on skin), age spots, and dark spots due to acne, pregnancy-related scars, skin trauma or use of birth control pills. It works by inhibiting tyrosinase, enzyme which is required to make melanin in skin cells. Melanin give the skin the dark color.
