History

Skin whitening originates in Japan, where Geishas painted their skin white to impress their clients. Though skin whitening creams are popular worldwide in modern day, the process of breaking down skin pigment by using enzymes or in some cases, reducing agents called hydroquinone can be harmful to health.

Function

The function of skin bleaching in most cases is purely cosmetic for those who want to make their skin color lighter. In some cases, patients of skin disorders bleach a certain area of skin to even out their tone. This process is also sometimes used for genital or anal bleaching.

Physical Risks

Skin bleaching should never be considered without the help of a medical professional. Hydroquinone, which is used in many skin bleaching creams, has been proven to cause leukemia in mice. In the U.S., creams containing 2 percent hydroquinone or less is sold over the counter. Additionally, many of these creams contain mercury that can cause mercury poisoning.

Mental Risks

Changing skin color can be hazardous to mental health prompting confusion about identity, self-esteem and race. Any change in a person's physical appearance can be conspicuous and can be subject to unwanted attention, such as ridicule and gossip.
