This is going to cause a wrinkle in the lives of a few wealthy Beverly Hills residents lives. An Argentinian doctor who once used the homes of the wealthy to inject clients with an illicit anti-wrinkle chemical has been sentenced to 18 months in federal prison.

Daniel Tomas Fuente Serrano was sentenced to two years in prison. Prosecutors for the case say he gave the illegal injections at various places, including parties, where up to 30 wealthy clients sipped cocktails and were injected with silicone smuggled into the U.S. Oh great and injection party. Is that what they do in Hollywood? Clients of Serranos are said to have included Lionel Richie, Richies ex-wife Diane and Shawn King, the wife of CNN talk show host Larry King.

Serrano charged his clients thousands of dollars for the injections, yet he wasn’t licensed to practice medicine in the United States. The injections consisted of industrial grade silicone used to lubricate auto parts, as well as medical grade silicone which is often used for eye surgeries but has not been approved for the treatment of wrinkles.

Serrano admitted to having given illegal injections from 2001 until November of 2004, earning more than 1.6 million US. Last year he plead guilty to several counts including conspiracy and the receipt of illegally imported merchandise.

It’s not surprising that some of Serrano’s clients have reported that they’ve developed problems after the injections. Diane Richie has been charged with aiding and abetting Serrano.
