Dr. Bita Farrell, a U.S.-based aesthetic specialist, became her own “lab rat” to show how Botox works in real life. In a viral video, she injected only one side of her lips to reveal the difference after two weeks. “You can see the treated side is fuller and the cupid’s bow is higher,” she explained, smiling to show how the lip moved differently.

The treatment, called a split lip-flip, helps reduce fine “smoker’s lines” and makes the lips look naturally plumper. Dr. Farrell noted that even a small amount of Botox “can make a big difference when placed correctly.” Viewers were amazed at how defined one side looked compared to the untreated half.
She also reminded followers that Botox results are temporary, lasting about three to four months. While the effects fade, long-term use can sometimes cause mild stiffness or changes in facial expression. Still, Dr. Farrell’s experiment shows how subtle, well-done Botox can enhance natural beauty — without losing your smile. Would you ever try it?
