KINGSTON, Jamaica (AP) — Mikeisha Simpson covers her body in greasy white cream and bundles up in a track suit to avoid the fierce sun of her native Jamaica, but she's not worried about skin cancer.

The 23-year-old resident of a Kingston ghetto hopes to transform her dark complexion to a cafe-au-lait-colour common among Jamaica's elite and favoured by many men in her neighborhood. She believes a fairer skin could be her ticket to a better life. So she spends her meager savings on cheap black-market concoctions that promise to lighten her pigment.

Simpson and her friends ultimately shrug off public health campaigns and reggae hits blasting the reckless practice.

"I hear the people that say bleaching is bad, but I'll still do it. I won't stop 'cause I like it and I know how to do it safe," said Simpson, her young daughter bouncing on her hip.

People around the world often try to alter their skin color, using tanning salons or dyes to darken it or other chemicals to lighten it. In the gritty slums of Jamaica, doctors say the skin lightening phenomenon has reached dangerous proportions.

"I know of one woman who started to bleach her baby. She got very annoyed with me when I told her to stop immediately, and she left my office. I often wonder what became of that baby," said Neil Persadsingh, a leading Jamaican dermatologist.

Most Jamaican bleachers use over-the-counter creams, many of them knockoffs imported from West Africa. Long-term use of one of the ingredients, hydroquinone, has long been linked to a disfiguring condition called ochronosis that causes a splotchy darkening of the skin. Doctors say abuse of bleaching lotions has also left a web of stretch marks across some Jamaicans' faces.

In Japan, the European Union, and Australia, hydroquinone has been removed from over-the-counter skin products and substituted with other chemicals due to concerns about health risks. In the United States, over-the-counter creams containing up to 2 per cent hydroquinone are recognised as safe and effective by the US Food and Drug Administration. A proposed ban by the FDA in 2006 fizzled.

Lightening creams are not effectively regulated in Jamaica, where even roadside vendors sell tubes and plastic bags of powders and ointments from cardboard boxes stacked along sidewalks in market districts.

"Many of the tubes are unlabelled as to their actual ingredients," said Dr Richard Desnoes, president of the Dermatology Association of Jamaica.

Hardcore bleachers use illegal ointments smuggled into the Caribbean country that contain toxins like mercury, a metal that blocks production of melanin, which give skin its colour, but can also be toxic.

Some impoverished people resort to homemade mixtures of toothpaste or curry powder, which can stain skin with a yellowish tint.

The Jamaican Ministry of Health does not have data on damage caused by skin-bleaching agents, though dermatologists and other health officials say they have been seeing more cases.

Eva Lewis-Fuller, the ministry's director of health promotion and protection, is redoubling education programs to combat bleaching in this predominantly black island of 2.8 million people, where images of fair-skinned people predominate in commercials for high-end products and in the social pages of newspapers.

"Bleaching has gotten far worse and widespread in recent years," she said. "(Bleachers) want to be accepted within their circle of society. They want to be attractive to the opposite sex. They want career opportunities. But we are saying there are side effects and risks. It can disfigure your face."

Health officials are running warnings on local radio stations, putting up posters in schools, holding talks and handing out literature about the dangers. But a similar anti-bleaching campaign in 2007 called "Don't Kill the Skin" did nothing to slow the craze.

The bleaching trend is sparking a growing public debate. Even dancehall reggae hits celebrate the practice, or condemn it.

The most public proponent of bleaching is singing star Vybz Kartel, whose own complexion has dramatically lightened in recent years. His 'Look Pon Me' contains the lines: "Di girl dem love off mi brown cute face, di girl dem love off mi bleach-out face."

Kartel, whose real name is Adijah Palmer, insists that skin bleaching is simply a personal choice like tattooing.

Christopher AD Charles, an assistant professor at Monroe College in New York City who has studied the psychology of bleaching, said many young Jamaicans perceive it "as a modern thing, like Botox, to fashion their own body in a unique way."

Others, however, say it raises awkward questions about identity and race.

"If we really want to control the spread of the skin-bleaching virus, we first have to admit that there's an epidemic of color prejudice in our society," said Carolyn Cooper, a professor of literary and cultural studies at the University of the West Indies, writing in The Jamaica Gleaner newspaper.

Felicia James, a 20-year-old resident of the Matthews Lane slum, said skin bleaching just makes her feel special, like she's walking around in a spotlight. She was taught to bleach by her older sister and her friends.

"It's just the fashionable thing to do. After I bleach, I'm cris," she said, using a Jamaican term for cool. "Plus, a lot of the boys are doing it now, too."
