Renee Zellweger's appearance at the Oscars sparks line and wrinkle treatment rumours
26 February 2013Rumours are flying that Renee Zellweger may have undergone a non-invasive surgical procedure after she walked the Oscars red carpet looking surprisingly fresh-faced. The 43-year-olds forehead was free of lines, which sparked reports that she may have had Botox injections to keep wrinkles at bay. Botox is a purified protein that works by relaxing the contracted muscles in the face that cause wrinkles, thus creating a more youthful look. Patients receive the injections every six weeks and over time, it works to re-educate the muscles. There has been no official comment from Zellwegers people, so it is currently unclear if she has actually undergone the procedure. Many famous faces have admitted trying Botox in the past, such as Nicole Kidman, Kelly Ripa and Jennifer Aniston.
