It's the busiest season for cosmetic surgeons in Hollywood. The Oscars are this Sunday and the stars have been preparing for weeks. Forbes has interviewed a few of the celebrity cosmetic surgeons and dermatologists in Beverly Hills. They've talked to Dr. Nicholas Nikolov, Dr. Renato Calabria (pioneer of the one-stich face lift), Dr. Richard Ellenbogen (who does the Volumetric Face Lift) and cosmetic dentist Dr. Jorge Blanco.

None of these doctors will reveal who any of their famous clients are but they do talk about some of the most common 'secret' cosmetic surgery procedures that celebrities undertake in the weeks before the Oscars. They also provide before and after pictures of all the procedures discussed.

Check out their Plastic Surgery Secrets of the Stars article.
