A plastic surgeon has warned Jennifer Aniston against having further cosmetic surgery, amid rumours that she is considering a facelift, a brow lift, and more breast augmentation.

The 41-year-old actress, known for her natural beauty, has previously admitted to a nose job and receiving Botox.

However, her representative has denied that she has had breast augmentation or is planning further procedures.

Friends of Aniston are reportedly concerned that more surgery would damage her appearance.

Dr Richard Chaffoo, a triple-board-certified plastic surgeon, based in La Jolla, California, has praised Aniston’s “natural, wholesome beauty” and said that the nose job she had previously undergone was a subtle change that “doesn’t look operated on or cosmetic”.

He has also suggested that she may have had breast augmentation but added that any difference is so slight that it could just be a “boost from a good bra”.

Dr Chaffoo has advised Aniston against having any further procedures, particularly at her relatively young age.

“She’s quite youthful”, he said, “a facelift, brow lift or fillers would impart an unnatural appearance.”

He added that even the most successful cosmetic surgeries can become counterproductive if overused.

“You lose the natural look in your face”, he warned.

“It becomes distorted and disproportionate. The hairline and brows can become distorted or raised and lose symmetry. The face can take on a startled look.”

Dr Ayham Al-Ayoubi, the medical director of the London Medical and Aesthetic Clinic, has also cautioned against Aniston having any further surgery.

“Jennifer is at a turning point,” he said.

“Any more treatment will ruin her natural beauty. She looks beautiful at the moment. But if she has more work, the public will start to notice.”

Aniston’s natural appearance has always been a selling point of her public image, which is part of the reason that rumours of her having cosmetic surgery have always been of interest to the media.

She has previously been open about her use of Botox, describing it as “part of my job”, but added that she regretted having tried it.

Despite the rumours, Aniston’s representative has maintained that she is not planning to have any further procedures.

Aniston herself has spoken about her concerns over ageing, stating in an interview with InStyle magazine that she finds it “hard to watch myself ageing”.

Fans and friends of the actress have taken to social media to voice their concerns about the potential impact of further surgery on her natural beauty.

One Twitter user wrote: “I hope Jennifer Aniston stops with the surgery. She doesn’t need it and it’s starting to look bad.”

Another said: “She’s beautiful the way she is. She doesn’t need to ruin her face.”

Aniston has not yet responded to the latest rumours about her potential surgery plans.

However, it is clear that the debate around cosmetic surgery and its potential impact on natural beauty is likely to continue, particularly in the context of celebrities whose appearance is so closely scrutinised by the media and the public.
