22 March 2012American actress Susan Sarandon has spoken about using cosmetic surgery to improve her appearance. Speaking to People magazine, the 65-year-old said she'd opted to have liposuction in order to remove fat composites from her face.The Hollywood star, known for her roles in films including Dead Man Walking and Thelma and Louise, said the procedure had focused on the areas under her eyes and chin. According to a report by the Toronto Sun, she also admitted that she hasn't ruled out having further cosmetic work such as Botox injections. But while the actress has been open about her use of cosmetic surgery to retain her looks, she told the magazine she would be careful not to go too far. She said: "If you can't move your face or you're unrecognisable, I don't see how that's a productive enhancement. You don't want to look like a female impersonation of yourself." Liposuction, or fat removal surgery, was the most popular invasive cosmetic procedure performed in the US last year, according to data released by the American Society for Aesthetic Plastic Surgery.
