hydroquinone
In different concentrations hydroquinone inhibits or prevents skin from making the enzyme responsible for triggering melanin, the chief pigment that gives skin its color (Source: Journal of Drugs in Dermatology, March 2010, pages 215-218). Over-the-counter hydroquinone products can contain 0.5% to 2% concentrations, with 2% being the most effective OTC amount. At the pharmacy, 4% concentrations of hydroquinone (and sometimes even higher) are available by prescription only. A concentration of 12% hydroquinone actually prevents the production of melanin altogether.
One critical point to keep in mind: hydroquinone can turn a strange shade of brown with prolonged, daily exposure to air or sunlight. When you are considering a hydroquinone product, it is essential to be sure it is packaged in a non-transparent container that doesn't let light in and that minimizes the amount of air exposure. Hydroquinone products packaged in jars are absolutely not recommended because once opened they quickly become ineffective.
