JUST like her music, Taylor Swift's looks have changed over time — but one pro thinks that she's had a bit of help.
An aesthetics doctor pointed to differences in the 34-year-old Karma singer's face that he says are signs of a little nip-and-tuck.
From her country days belting Teardrops on My Guitar to her more emo pop The Tortured Poets Department tracks, Taylor Swift's music isn't the only thing that's evolved throughout the years.
CEO Dr. Justin Harper chronicled the pop princess' injectables path over the last decade to her current look.
But he doesn't recommend that other women use some of the same techniques, citing things that can potentially go wrong.
BABY FACE
Taylor Swift burst onto the entertainment scene in 2007 with bright blond curls and a happy grin.
Dr. Harper admitted that at 18, she looked "very young" for her age.
"She already had these facial folds and it was natural back then," he said.
Often called smile or laugh lines, nasolabial folds are creases in your skin extending from both sides of your nose to the corners of your mouth.
The creases can become prominent and permanent as you age.

"If you have the folds in your face, it's because the structure of your face is built for the folds when you're youthful," Dr. Harper said.
BLOND LEGEND
Fast forward almost a decade later and Taylor Swift was seen sporting a chic blond platinum bob in 2016.
In her late 20s, she should have looked visibly older but appeared to have fewer fine lines and wrinkles than when she was a teenager.
This is when Dr. Harper suspects she got extensive filler done.
There is a running theory among many plastic surgeons and aesthetics pros that celebrities drastically change their hair to divert attention from their surgical results.
They may add or eliminate bangs, change the color, or go for a dramatically short length, and the 12-time Grammy Award winner did all of the above.
Her smile lines were practically non-existent in a photo Dr. Harper examined from the mid-2010s, even as she attempted to make a soft smile.
He suspects that Taylor has had nasolabial filler around her mouth, chin shadowing near her marionette lines, and some filler around her pyriform aperture right next to the nose.
Dr. Harper said it's "not good to make them go away completely."
"If I had filler trying to smooth it out, even if I'm good, even if I can make the lines go away, I fundamentally make somebody look more pushed out, wider, more catlike," he explained.
"You can see how the mouth naturally looks more pushed out," he explained.
Dr. Harper also said that there is a "weird flatness" in that.
As a result of the stabilizing filler, he added that she doesn't look as expressive and "couldn't really smile properly" in photos.
"What you're doing is adding filler or bulk to the area that has to animate or express, which is important for a performer," he said.
There's a reason why that is a popular area for cosmetic work, he added.
"This is because people want that filtered look, but smile lines are natural," Dr. Harper explained.
PRESENT-DAY PRINCESS
Now in the present day, Dr. Harper believes that Taylor has probably had a little bit of jawline filler and "more than he would like."
"You can see the filler kind of in the marionette line," he added.
Another addition is "some work done in her cheeks," but "obviously not a lot."
She may not have chipmunk cheeks, but the filler subtly lifts her face.

A major difference Dr. Harper noticed was a nose lift because "it's much more narrow at the nasal base."
"Our noses don't get more narrow as we age. It gets wider typically," he explained.
