Susan Sarandon thinks she looks ''tired'' when she wears nude lipstick.

The 70-year-old actress - who is the brand ambassador for L'Oréal Paris and represents the brand's Age Perfect skincare and hair colour range - doesn't think she can ''get away'' with wearing pale shades of lip products like the Kardashian/Jenner brood because she thinks it makes her look worn out.

Speaking about her beauty hacks and the trends she stays away from, the red head movie legend said: ''I'm not someone that can get away with the Kardashian nude lip thing - I always look so tired. So I always find that I need a lip colour.''

The 'Stepmom' star has revealed she never used to have a beauty or skincare routine when she was younger and thinks she is ''lucky'' she boasts youthful looking skin and is in ''good shape''.

She said: ''I don't think I had a routine when I was young. I never paid any attention at all and I'm lucky that I am in as good a shape as I am.''

But Sarah has since changed her former ways and has become more ''aware'' of her skincare regime and makes a conscious effort to moisturise her skin, stay hydrated and not smoke to maintain her flawless complexion because she believes smoking ''robs'' people of ''everything''.

Speaking to Hello! magazine about how her routine has changed over time, and the changes she has made to her lifestyle to boost her aesthetic, she said: ''But yes, I am much more aware of moisturising, drinking more water and not smoking cigarettes. I think cigarettes and too much sun are so damaging to your complexion - they just rob you of everything. ''
