Carey Mulligan turned down Botox at the age of 23.

The 33-year-old actress has revealed that when she began her film acting career she sought some professional beauty help for lines underneath her eyes and was immediately offered the wrinkle-smoothing injections.

In an interview with the Sunday Times' Style magazine, she said: ''Someone tried to give me Botox when I was 23. I was bothered by the lines under my eyes, and went to see someone, hoping for a cream, but they said, 'We can just put a bit of Botox in.' And I replied, 'My whole job is about me moving my face!' ''

The 'Great Gatsby' actress raises three-year-old Evelyn with her husband, Mumford & Sons frontman Marcus Mumford, and she has revealed that her daughter is very honest with her mother when it comes to her imperfections and often comments on her forehead wrinkles.

She said: ''At the moment my daughter's favourite thing is to push my forehead together and shout, 'Mummy, lines!' There is nothing like a little bit of toddler truth.''

The 'Mudbound' star has admitted that having her daughter has changed her outlook on beauty and made her stop fretting about walking the red carpet.

She said: ''When I was younger I was riddled with insecurities - red carpets made me feel like crying. I was scared of wearing big expensive dresses. It felt like a model's job and I didn't know what role I was meant to play. The first time I did press after I'd had my daughter she was one month old. I literally ran to the red carpet, did it, ran home, pulled off my dress and fed her in my Spanx and six inch heels.''
