E
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.

Whether playing, shopping, studying, or just surfing, today’s kids are taking advantage of all the World Wide Web has offered. When it comes to their personal information online, though, who’s in charge? The Federal Trade Commission has established new rules to make sure that youngsters’ privacy (隐私) is protected while they are online.

Website operators must:

Post the privacy policy. Websites directed to children or to collecting information from kids under 13 must post a notice of their information-collection practices that includes:

*Types of personal information they collect from kids, such as name, home address, e-mail address, or hobby.

*How the site will use the information, for example, to notify contest winners, or make the information available through a child’s participation in a chat room.

*Whether personal information is forwarded to a third party.

Get parental permission. In many cases, a site must obtain parental permission before collecting, using, or disclosing personal information about a child. Permission is not required when a site is collecting an e-mail address to respond to a request from the child, to provide notice to the parent, to ensure the safety of the youngster or the site, or to send a newsletter—as long as the site notifies parents and gives them an opportunity to say no to the arrangement.

Parents should:

Look for a privacy policy on the website. The policy must be available through a link on the website’s homepage, or on the homepage of the section for kids. Read the policy closely. If you find a website that doesn’t post basic protections for children’s personal information, ask for details about their information-collection practices.

Decide whether to give permission. You can give permission and say no later to collecting, using or disclosing your children’s information.

Ask to see the information your child has given. Make sure that your kid’s information isn’t given out improperly.
