In a bid to prove the power of Botox, this dedicated doctor injected one side of her face with the stuff.
Dr Bita Farrell is a big fan of the prescription drug botulinum toxin and the cosmetic benefits it can bring to her clients.
To demonstrate how a few strategically placed injections can drastically alter a person's appearance, she said goodbye to the symmetry of her face for a brief period.
Dr Farrell, who is a world-renowned aesthetic doctor based in California, offered herself up to be a 'lab rat' for the experiment.

It's important to note that she is a qualified professional with over two decades of experience in this field - so don't get any ideas about trying this out at home, lads.
The medic explained that she decided to walk her 141,000 Instagram followers through the process for 'the sake of science and education'.
To show what kind of difference Botox can make, she jabbed the right side of her face with the neurotoxic protein which temporarily paralyses muscles.
It blocks signals being sent from nerves to the muscles, so that they can no longer contract and this gives the appearance of smoother, more youthful-looking skin.
Dr Farrell explained that she had specifically targeted the DAO muscle, which pulls down the corners of the mouth, and the platysma muscle, which contributes to facial expressions and mouth movements.
A fortnight after she after gave half of her face a pamper, the Natural Aesthetics Center founder then shared a progress update to show the impact that the injections had.
In the clip which was originally shared in June 2024, Dr Farrell explained: "Two weeks later, I present my results as I try and contract my lower face muscles.
"You can see that the platysma muscle on this [left] side is really contracting and pulling my jawline down, and so is my DAO, pulling the corner of my mouth down," Dr Farrell said.
Referring to her right side, which she injected with Botox a fortnight earlier, she added: "I'm really trying to pull this side!"
Describing the difference she could see on the right side of her face, Dr Farrell went on: "The cheek rides a bit higher, this nasal labial fold seems softer and so does my shadow at the marionette on this side."
She offered further details about how the popular cosmetic treatment works in the caption of the post.
"Muscles of the face either pull up or pull down," Dr Farrell explained. "When the muscles that pull the lower face down (platysma and DAO) are injected and relaxed with a Neuromodulator such as Botox, the muscle that pulls the mid face up (zygomaticus or cheek muscle) dominates and pulls the face up!
"This can help reduce the appearance of marionette lines, jowls, frown (rbf, or sad face), and the nasolabial folds. It also lifts the neck and can sharpen the jawline and make the cheeks appear a bit fuller and more lifted."
"Results last average 3-4 months, and any of the FDA approved Neuromodulators can be used," she said, before joking: "Now, I better go inject the other side to even things out!"
Dr Farrell also previously injected Botox into one side of her upper lip to show how Botox works in this area. Give that woman a raise!
