The American actress, who has English and Irish roots and has spent a lot of time living in London, tells NewBeauty magazine she is a lot more comfortable about getting older than some of her peers in the U.S.

And she thinks that's mostly down to the fact she spends so much time in the U.K.

"I tend to observe women in the U.K. approaching it less obsessively, than say, those in Los Angeles," she tells the publication. "There seems to be less of a preoccupation with it and more of an acceptance of the natural face and the natural ageing process.

"I think in Europe, in general, there’s a sense that women who age naturally can be beautiful, whereas I’m not so sure that’s the perception in America, specifically in L.A. I think that it’s seen as a flaw, somehow - like wrinkles are a flaw."

But Anderson wants to make it clear she's not judging those who choose to battle the ageing process with the help of a nip or a tuck or the use of Botox, adding, "There will always be the desire, as women see themselves getting older, to stop the process."

And the 47-year-old admits she might become one of the women looking for a little cosmetic help in the years to come: "Ultimately, it comes down to embracing that process and embracing one’s self at the age that one is, which is hard. I’m sure I’ll find myself along the way in some situations saying, 'Do I? Should I? Would I?'"

Meanwhile, Gillian admits she started really taking care of her skin when she started noticing a few signs of wear and tear a few years ago.

"Once I started seeing that my skin was suffering, I began to pay more attention to it," she explains. "It’s not a huge part of my life, but I make an attempt to use some of the stuff that's out there. And, you know, I think it works. I think my skin definitely feels better."
