Julianne Moore, 65, shows off her taut visage during rare red carpet appearance at Cannes

Julianne Moore was looking remarkably fresh-faced during a rare moment on the red carpet at Cannes on Saturday.

The 65-year-old actress was attending the Kering Women in Motion: Julianne Moore event as part of the annual film festival, wearing an elegant black ensemble that she paired with fluffy red slippers.

Unusual footwear aside, it was Moore's amazingly taut face that undoubtedly turned heads.

While many stars visit their plastic surgeon on a regular basis, Moore - who made another rare outing with her family at Love Rocks NYC in March - has long maintained she hasn't done any cosmetic tweaking.

Back in 2010, the Oscar winner told Allure magazine she would never do Botox.

'I hate to condemn people for doing [Botox], but I don’t believe it makes people look better. I think it just makes them look like they had something done to their face. When you look at somebody who's had their face altered in some way, it just looks weird,' she said.

Instead of invasive treatments, Moore takes care of her skin.

'My mother was very fair-skinned, and she was concerned about us getting sunburned all the time; she wouldn't even let us go outside at the beach until after three o'clock, and we could only stay for a little while,' she previously told Vogue.

'My skin-care routine has gotten more and more complicated as I get older,' she said, adding that she doesn't use a lot of makeup. 'I like to be able to see the freckles in my skin and color in my skin as well.'

Speaking to WSJ, the Sirens star shared: 'My big thing is that I will rotate coffee and green tea throughout the year and I think that helps my skin. I'll drink coffee for six months, then switch to green tea for six months.'

She also boosts her daily hydration by adding chlorophyll to her drinking water. She drinks two big glasses of the concoction when she wakes up. 

'Someone told me a long time ago that it was really good for your skin, so I’ve always done it,' she said.

Moore has focused on inner growth as opposed to outward beauty.

'How do we continue to challenge ourselves, to interest ourselves, learn new things, be more helpful to other people, be the person that your friends and family need or want?' she told As If Magazine in 2021.

'How do we continue to evolve? How do we navigate life to have even deeper experiences? That should be what aging is about.'

Moore, who has two children, Caleb, 28, and Liv, 24, with husband Bart Freundlich, maintained she's not overly consumed by aging because it's a fact of life and something that can't be controlled.

'There’s so much judgment inherent in the term "aging gracefully,'' the actress said. 'Is there an ungraceful way to age? We don't have an option, of course. No one has an option about aging, so it's not a positive or a negative thing, it just is.'

She added: 'It's part of the human condition, so why are we always talking about it as if it is something that we have control over?'
