Actress Emma Thompson remains determined to avoid cosmetic surgery, insisting it is "psychotic" to have Botox injections.

The Oscar winner joined her fellow British screen stars Kate Winslet and Rachel Weisz in 2011 to form the self-styled 'British Anti-Cosmetic Surgery League' to rally against unnecessary operations.

Thompson, 54, insists she is still vehemently against facelifts, implants or wrinkle-busting Botox injections two years on, and is more convinced than ever that she will not succumb to pressure and go under the knife.

She tells U.K. talk show host Graham Norton, "Look at me, I'm normal. I really wouldn't do anything. It's psychotic to have your body opened up and stuff put in and injecting yourself with poisons."
