Lifestyle Style Kate Winslet Will Prove to You, in Person, That She Hasn't Had Botox (Just Watch Her Face!) Seriously - just watch her! By Alex Apatoff Published on June 18, 2015 04:46PM EDT She may joke about it, but there's no funny business when it comes to Kate Winslet's ageless beauty. Evan Agostini/Invision/AP The 39-year-old proved Wednesday at the N.Y.C. premiere of her film A Little Chaos that Botox isn't the secret to her flawless skin. "Watch my forehead," she said to a reporter who asked about how she stays looking so youthful. She leaned in and pointed right between her eyebrows while scrunching her face. "See that movement? I'm very proud of that movement." The mom of three told PEOPLE in an interview earlier this year that her signature look isn't going anywhere. "I have the kind of wrinkles that are here to stay now," she said. "You know, not just the ones where you wake up in the morning and you go, ‘Oh, that will go away in two hours' time.' No, they're there. That's the way that it is." RELATED PHOTOS: Barefaced and beautiful! Celebs' best makeup-free selfies! But whether it's love, acceptance or her access to Lancôme's huge supply of skincare, Winslet, who turns 40 in October, says she's never felt more at peace and happy with herself. "I've got boobs and a bum and a man who loves me," she told InStyle. "I still dip in and out of feeling confident as much as the next person, but I can genuinely say, now more than ever, that I really do love the fact that I'm curvy."
