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 group．As a result, more and more people with dark skin are using skin-lightening products, even if they may face health risks．
Many people believe that having whiter skin will improve their lives．They 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 contain chemicals that make skin lighter．This process is also called bleaching （漂白）．But some of the chemicals are extremely dangerous．One chemical has been linked to kidney （肾） damage and some kinds of cancer．It also causes low birth weight in babies when used by mothers-to-be．
At first, bleaching products make the skin color lighter．But after long-term use they can cause problems．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 problems 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．
