"My family are generally on the younger-looking side," she said. "Even my dog is nine and looks like a puppy."
The "Underworld" star said hasn't "had any" Botox, but isn't "against people having it." However, Beckinsale admitted that she gets irritated that people assume she's gotten Botox injections.
"I do get pissed off. It's sort of a given that I've had it, which I just literally haven't," she said.
The "Pearl Habor" actress then explained the reason why she's never gotten Botox injections.
"I'm frightened of paralyzing my face," she told the newspaper. "My mum's voice is in my head, very loud, at all times. My mum wouldn't even get a facial, she is suspicious of anything like that, and looks f------- radiant and amazing. I know if I did do Botox, I'd be the one that would get the droopy eye, and my mum would go, 'I f------ told you! See? You should never do that.'"
Ultimately, Beckinsale said that aging isn't very important to her due to the fact that her father, Richard Beckinsale, passed away from a heart attack at 31.
"I've been so aware of the possibility people can drop dead at any time," she explained. "People started trying to worry me about turning 40 when I was turning 33. If you overload it like that, you're going to make the person not give a s---."
Beckinsale also pointed out that women are held to certain beauty standards.
"I think, when you start out, if people perceive you as attractive it's helpful at first," she said. "If people start thinking that's your main thing, I don't think that's helpful to anyone, least of all you. I think women are damned anyway. I don’t just mean actresses. You're seen as attractive, you're not seen as attractive. You're seen as too young, you're too old. Where is the f------- sweet spot for women? At some point you just have to go, 'Bollocks -- this is me.'"
