Most people see Botox as a simple cosmetic “wrinkle eraser,” but one doctor decided to prove it’s much more than that — and the results left viewers stunned.
Dr. Bita Farrell, a board-certified physician with more than 20 years of experience (and over 268,000 Instagram followers), turned herself into her own experiment. Instead of a full-face treatment, she injected Botox into only one side of her face — and then filmed the difference for the world to see.
📹 The Half-Face Botox Experiment
Two weeks before posting her viral video, Dr. Farrell injected the right side of her face with Botox, targeting the DAO muscle (which pulls down the corners of the mouth) and the platysma (which affects jawline and neck movement).
When she compared the two sides on camera, the results were jaw-dropping:
- Left side (no Botox): muscles contracted strongly, pulling the jawline and mouth downward.
- Right side (Botox injected): muscles barely moved, giving a lifted, smoother look.
“You can see that the platysma is pulling my jawline down on this side,” she explained while pointing to her untreated half. “But here [on the injected side], I’m really trying to move it — and nothing!”
The changes were subtle but clear: her cheek looked slightly higher, her smile folds softened, and her jawline appeared sharper.
💉 How Botox Actually Works
Botox (or other FDA-approved neuromodulators) works by relaxing muscles that pull the face downward. When those muscles are softened, the upward-pulling muscles — like the zygomaticus in the cheeks — naturally take over.

🌟 What Viewers Had to Say
Naturally, the internet had strong reactions.
One fan wrote: “Wow… a doctor willing to test on herself? That’s so cool and educational.”
Another added: “This is the clearest demonstration I’ve ever seen of what Botox actually does.”
Some even admitted they preferred her natural side — but most agreed the demonstration was eye-opening.
👩⚕️ Final Takeaway
Botox isn’t just about “freezing your face.” When used strategically, it can reshape how muscles pull, helping lift and soften the face without surgery.
And don’t worry — Dr. Farrell made sure to inject the other side afterward. As she joked: “Now I better even things out!”
