"It looks like she had lip augmentation with a temporary injectable filler like Restylane, Juvederm or Hylaform," says NYC plastic surgeon Michelle Copeland, M.D. "The nice thing is, it isn't permanent [results last four to eight months], so if you don't like it, you don't do it again," she says. The cost? Syringes range from $750 to $950 each—typically one or two are required, says Dr. Copeland. For more permanent results, Dr. Copeland, who does not treat Richie, says injections of the patient's own fat are used.
