      In many societies, there is often greater acceptance of light skin than dark skin. Light skin may be seen

as a mark of beauty, intelligence and success. These beliefs can lead to social pressure even within the same

racial or ethnic group, if some members are darker skinned than others.

      The result is that skin lightening has become a common activity across Africa, Asia and other areas of

the world. More and more people with dark skin are using skin-lightening products, even if they may face

health risks.

      They believe that having whiter skin will improve their lives. Many people think they will have a better

chance of getting a job or marrying into a better family. Or they want to look like what their society generally

considers beautiful.

      Some beauty care products and soaps contain chemicals that make skin lighter. This process is also called

bleaching. But some of the chemicals are extremely dangerous. One of the chemicals has been linked to

kidney (肾) damage and some kinds of cancer. It also causes low birth weight in babies when mothers use it

during pregnancy.

      At first, bleaching products make the skin color lighter. But after long-term use they can cause problems.

They can even make some skin darker. The chemicals in the products block and break down the natural

process that gives color to skin. The skin loses its natural barrier to protect against sunlight. Then the skin

can become thick and discolored. Usually the person will use more of the product in an effort to correct the

problem, but this only makes it worse.

      Fatimata Ly treats skin conditions in the Senegalese capital, Dakar. Doctor Ly says skin bleaching has

become a problem throughout Senegal. She says the chemicals are now more dangerous because they are

stronger. Some cases have resulted in blackened fingernails, infections and permanent skin damage.

      And these are not the only risks. Experts say some people who change their skin color suffer emotional

damage. They feel regret and sadness. They feel that instead of risking their health, they should have learned

to love and accept their skin color as it was.
