In much society, 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 pressures even within the same group, if some members are darker than others.

The result is that skin lightening has become very common across Africa, Asia and other areas of the world and more people with dark skin are using skin-lighting products, even if it means they may face health risks. They believe that having whiter skin will improve the quality of their lives. Many people think they will have a better family. Or they want to look like what their society generally considers beautiful.

Some beauty care（美容） products and soaps contain chemicals that make skin lighter. However, some of the chemicals are extremely dangerous. The chemicals in the products block and break down the natural barrier(障碍) 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, which just makes things even worse. Doctor Ly says some chemicals are so dangerous that they may lead to blackened fingernails, infections(感染) and serious skin damage.

And these are not the only problems. Experts say some people who change their skin color suffer emotional damage. They feel regretful and sad. They feel that instead of risking their health, they should have learned to live and accept their skin color as it was.
