People use bleaching creams to remove dark spots and to lighten the entire complexion. These creams, also known as a skin lightening creams, work by breaking down melanin in the skin. Melanin is what creates a person's color. The key ingredients in these creams usually hydroquinone, tretinoin, mercury and topical corticosteroids.
Hydroquinone
Prolonged use may result in exogenous ochronosis, when parts of your skin and nails that have been exposed to the Sun begins to turn an irreversible blue-black color. Exogenous ochronosis also cause a person to lose the elasticity in the skin that makes a person seem to age faster. It also slows down the healing process. A normal rock that can heal over two days, with prolonged use of hydroquinone, it may take a week to heal. According DermNet NZ, the use of hydroquinone in conjunction with a diet full of fish, eggs and beans can cause a person's urine and sweat smell like stinky fish. Hydroquinone can also cause white spots to develop on a person's skin.
Tretinoin
