Lindsay Lohan’s transformation explained by cosmetic surgery experts

What is her little secret?

Lindsay Lohan dressed to impress at her recent press tour for her new Netflix vacation rom-com, “Our Little Secret,” but it’s not just her outfit that’s grabbing the public’s attention.

The beloved movie star – who has had her fair share of ups and downs over the years – seems to have undergone both an internal and external transformation.

Although Lohan, 38, claims she fights aging with a simple skin care routine, Page Six gathered cosmetic surgery experts — none of whom treated the “Mean Girls” star — for their take on her impressive glow.

Jeune Aesthetics founder Pamela Weinberger tells us Lohan likely had a mix of injectables like Botox, an eyebrow lift, lip and cheek fillers, as well as surgical procedures like an upper blepharoplasty, an endoscopic facelift and submental liposuction, which removes fat from the neck and chin.

“Some results can be achieved with skilled injectors, but for transformations, these striking, surgical improvements seem likely,” says the Miami-based medical injector.

“But the secret sauce here is balance: skilled injectors and surgeons work together for a ‘natural-but-better’ look.”

Weinberger adds, “The best work has to look invisible. The magic is in how far the technology and artistry have come.”

Recognized plastic surgeon Dr. Ramtin Cashier agrees that Lohan likely went under the knife, noting upper and lower blepharoplasty, deep facelifts and neck lifts as possible procedures she had done.

However, the New York-based nose job expert doesn’t believe the “Freaky Friday” star had any nose jobs, and actually thinks the star may have reversed some of the bad procedures she had in the past.

“I think she’s dissolved what she had before,” Kassir says, adding that weight loss was also likely a contributing factor to Lohan’s changed appearance.

“Her face is definitely not what we call ‘pillow-faced’ or full. That could be because she either lost weight, had the filler dissolve or had it washed out during surgery,” he explains.

Dr. Ari Hoschander by KH Plastic surgery in New York City agrees: “The main reason I think she looks better is because she lost weight.”

“She didn’t get a facelift of any kind. I think she just lost a little weight,” says the board-certified plastic surgeon.

Weinberger shares that fans who want to achieve a youthful look like Lohan should follow the “holy trinity” of glow-ups: eating clean, vitamins and probably some peptides and NAD.

“Start with a healthy lifestyle,” she says, before joking that it’s “yes, boring” but “essential.”

All of our experts also point out that Lohan’s face looks much smoother, which was probably achieved by doing skin treatments like resurfacing lasers, chemical peels and micro-needling.

Hoschander tells us, “She did at most some lasers for the color and texture of her skin on her face—maybe a touch of filler, but definitely not much.”

People on social media have also speculated a lot whether the “Parent Trap” star has had a facelift.

Although most of our experts don’t think Lohan has had one yet, Dr. Samuel Lin explains why being under 40 does not necessarily exclude a patient as a candidate.

“Anatomy matters more than age when it comes to facelifts. There is no specific ‘right’ age for the procedure as it depends on individual anatomy and genetics,” says the board-certified plastic surgeon.

“While some candidates in their late 40s may be ready for a facelift, others may not experience sufficient skin loss until their 50s or later.”

Lin further explains that factors such as “age, genetics and lifestyle create a range of timelines for when a facelift may be beneficial.”

He concludes, “At the end of the day, your anatomy is the most important consideration, not your age.”
