The 67-year-old designer believes altering her features would make her insecure, reported Guardian online.
"The thing I'm afraid of is that I wouldn't recognise myself and then I would become insecure," she said.
Although the Belgian-born fashion icon insists she doesn't love ageing, she said she prefers to grow old gracefully as it shows she has lived her life to the full.
"I don't love ageing but, you know, the alternative to ageing - you don't want that. Ageing means living, right? And if you live and you're aged, it means you have a past and if you're OK with your past and have lived it fully, then it's OK," she added.
