Julianne Moore says Botox doesn't make you look younger. The 47-year-old actress has hit out at the widespread use of cosmetic treatment in Hollywood, insisting actresses should accept who they are and age naturally.She said: "I don't know why women do Botox. It doesn't make them look younger, it just makes them look like they had work done. You are not going to look the same as you did at 25. What are you going to do about it?"However, Julianne admits she does understand there is a lot of pressure within the movie industry for women to remain looking fresh-faced. She added: "It's hard for actresses. Our faces get to be blown up 50ft wide, and you see stuff that otherwise you wouldn't. People freak out."Botox is a cosmetic treatment which is injected - usually into the face - to battle wrinkles. It works by paralysing muscles in specific areas. Stars who are rumoured to have had Botox treatments include Elizabeth Hurley, Kim Cattrall, Kylie Minogue and Nicole Kidman.
