Farrah, 23, starred in the 2009 series of MTV reality show Teen Mom and suffered the frightening reaction after having filler injections in California yesterday (6 January).
After being whisked to the hospital's emergency department, Farrah shared several photographs of herself lying in bed. In one of the Twitter shots, she is wearing a strong painkilling patch on her left arm.
The other snap has been taken from the side to show the true extent of Farrah's swollen and puffy top lip.
Despite the horror, the US mum-of-one attempted to make light of the situation, telling her followers: "Girlfriends don't say I didn't warn ya ! #BOTCHED California #ER #fixit."
Farrah first found fame on reality show 16 & Pregnant when she was expecting her daughter Sophia. She later went on to star in spin-off series Teen Mom and has since been in and out of the headlines.
In 2013, Farrah was embroiled in a sex tape scandal after admitting she had hired a pornographic actor to appear in a film, Farrah Superstar: Backdoor Teen Mum, with her.
She is rumoured to have sold the rights to the footage for a whopping $1.5 million and has since made a follow up, Farrah 2: Backdoor and More.
Along with dabbling with a pop career, Farrah has also changed her appearance over the years after having several boob jobs.
In August, it was revealed that Teen Mom stars Catelynn Lowell, Maci Bookout and Amber Portwood are set to return for a new series of the show. Farrah, however, will not be appearing in the new episodes.
Meanwhile, fellow Teen Mom star Jenelle Evans has today announced her engagement to boyfriend Nathan Griifth.
