Washington ? A Florida company that promised its dietary supplement could erase cellulite agreed Tuesday to repay customers up to $12 million to settle federal charges of deceptive advertising.

The Federal Trade Commission had accused Rexall Sundown Inc. of Boca Raton, Fla., of making false and unproven claims in national advertising to market Cellasene, a pill containing herbal ingredients.

The FTC said sales of Cellasene exceeded $40 million in the United States and a typical eight-week regimen cost about $200.

“Hundreds of thousands of consumers were misled,” said Howard Beales, director of the FTC’s Bureau of Consumer Protection. “This case should alert advertisers to the fact that their chances of getting away with making unsubstantiated claims are slim to none.”

A spokeswoman for the company did not immediately return calls seeking comment. By settling, the company does not admit breaking any law.
