Jennifer Aniston has stepped out sporting a shock new look in recent weeks, leaving fans questioning whether she’s had work done to her face.

But rather than undergoing cosmetic procedures, sources close to the actress, 55, have revealed she’s been trying a string of extreme beauty treatments in a bid to maintain her youthful looks, including salmon sperm facials.

“Jen is a big believer in trying any beauty treatment once, she loves going to the top spas and getting whatever they have to offer. The salmon sperm facial is something she’s done quite a few times, it gives a great glow and is very soothing,” an insider tells Closer.

“She was also one of the first in her circle to start using snail mucin gel – she introduced that to all her friends. She also goes for vampire facials on her face, neck and chest several times a month because it’s natural way to build collagen. She loves that it’s nothing but her own blood and the results build over time. She puts a huge amount of time and effort into taking care of her skin – she has a routine morning and night that takes a good 30 minutes to complete with all sorts of expensive creams and serums that she’s found in her travels around the world.”

The source continues, “She jumped on the Korean beauty bandwagon way before it was popular and discovered all the best stuff. She’s a huge believer in prevention so as basic as it sounds sunscreen is part of her routine and she applies it head to toe every hour, on the hour, even when she isn’t leaving the house because she’s convinced the blue light from the computer and TV is just as damaging. She also has an infrared sauna she goes into religiously at home to help with her overall health and skin rejuvenation.”

Jennifer – who has been filming the new season of The Morning Show – previously opened up about having the salmon sperm facial for the first time. The treatment, which is also loved by Kim Kardashian, involves injecting small needles of fish sperm directly into the face to rejuvenate the skin.

The star explained that she opted to give it a go after it was recommended to her by an aesthetician. “First of all, I said, ‘Are you serious? How do you get salmon’s sperm?’” she recalled, before going on to admit that she’s always up for experimenting when it comes to beauty.

Earlier this year, Jennifer was spotted leaving a well-known Connecticut plastic surgery office – which specialises in face lifts and nose jobs, as well as offering Botox – with her pal Sandra Bullock. While it’s not known why she was there, it sparked rumours about her appearance.

The Friends star has admitted to having Botox in the past, but insisted it was not for her. “There is this pressure in Hollywood to be ageless,” she previously said. “I think what I have been witness to is seeing women trying to stay ageless with what they are doing to themselves, I am grateful to learn from their mistakes because I am not injecting s**t into my face. I see them and my heart breaks. I think, ‘Oh god, if you only know how much older you look.’ They are trying to stop the clock, and all you can see is an insecure person who won’t let themselves just age.”

In 2017, she also admitted that she had a nose job in her twenties. “I had [a deviated septum] fixed — best thing I ever did,” she said. “I slept like a baby for the first time in years.”

Now, our insider explains that while she’s feeling the pressure to stay as fresh-faced as possible, she’s mindful about taking it too far.

“Jen is under so much pressure to look good – she feels like her career depends on it and unfortunately it kind of does. She’s not a character actress, she’s made her living being the beautiful one so ageing in front of the camera is especially hard for her,” we’re told.

“Yes, she has plenty of resources and can get whatever she wants done at the surgeon’s office, but that comes with a huge risk because if her face noticeably changes that could wreak havoc on her career. That’s why she’s always put so much effort into finding natural solutions and testing out everything she hears about.”

As well as beauty treatments, diet and fitness are a huge part of Jen’s regime. She previously admitted that she does intermittent fasting, admitting, “I noticed a big difference in going without solid food for 16 hours.” She also explained that lunch and dinner are always “some form of vegetables or salad with protein”.

And when it comes to exercise, she enjoys boxing, yoga and cardio, which she does for at least 20 minutes each day. She previously said she feels “really beautiful” after working out, explaining, “Because I’ve taken care of my body, my endorphins are going, my blood is pumping. I’m taking care of the one body I have.”

Our source adds, “It’s not just what she puts on her skin and hair that she experiments with, she also takes a ton of vitamin supplements, and her entire diet and exercise routine is built around keeping her skin and body as firm as possible. She’s always been a big believer in yoga but in the past few years she’s added face yoga into her routine and insists that it helps keep her jawline tight.

“She’s not above getting Botox and filler and laser treatments from her dermatologist, but she’s also terrified of overdoing it, which is why she’s so gung-ho on all stuff she does to take care of herself, even if some people might think she’s a little whacky and over the top with it all, she doesn’t care because it’s helping to keep her looking way younger than her years.”
