The actress, 41, has told pals she fears she’s losing her looks — and, in a bid to life her spirits and ensure future movie roles, has decided on a radical makeover.

“Jen’s been visiting her New York-based dermatologist Dr Amy Wechsler a lot over the past few months,” a source told Britain’s Now magazine. “She’s been leaning on her a lot recently, not just when she’s in New York but also for phone consultations.

“They’re both into the whole mind-body connection, so they do chanting and visualization. And Jen loves that Dr Wechsler believes in being very subtle with her work. It’s painstaking but the finished product speaks for itself.”

The source says Jen’s love of wine is causing problems.

“She’s tried to cut down because she knows how aging it is, but she just can’t — even though it dehydrates her skin and causes her to look puffy the next day,” explained the pal.

“She thinks she looks saggy now.

“It’s a struggle for any woman to get old, but to age in the public eye is even harder. To top it off, she’s still single, so not only does she have to face scrutiny over her looks, she also has to live up to the expectations of the guys she dates — most of whom are way younger than her.”

Jen recently admitted she isn’t against Botox.

“I could do [Botox], and I mean these lines are getting deeper every day, but when I tell you what’s happened to me — these lines are just about living,” she said earlier this month.

“Look, I eat really well and I work out, but I also indulge when I want to. I don’t starve myself in an extremist way.

“You’re not taking away my coffee or my dairy or my glass of wine because I’d be devastated. My advice: just stop eating sh** every day.”
