A TikTok plastic surgeon known as ‘Dr Kim’ has gone viral for his uncanny before-and-after videos showcasing the radical transformation of his patients who are sometimes left looking unnatural.

Dr Kim’s TikTok page originally went viral last year, when people first noticed his weird before-and-after clips, but one of his videos recently attracted even more attention, making headlines all over the world and sparking a heated debate online. While many users of the popular video-sharing platform are convinced that Dr Kim is either one of the world’s worst plastic surgeons or that his account is some kind of joke, some believe that people’s perception is skewed by the short period of time between the before and after shots. Patients’ faces are not completely healed and they often still have bruises or are visibly swollen, but that’s how Dr Kim chooses to share their transformation.

Then there is the mystery behind Dr Kim. Who is he, where is he from, is a licensed plastic surgeon? No one really knows for sure. According to the Surgical Times, reverse-image searches of his profile picture suggest that he is Kim Ji-hoon, a doctor out of South Korea, but when calling the WhatsApp number listed in his account, people are invited to Shanghai, China to have work done. A facelift is reportedly priced at $50,000.

Dr Kim’s videos and his practices have sparked a heated debate both on social media and among plastic surgeons, but in the end, the fact remains that he appears to have a steady flow of new clients, and some of them actually praise his work. So even though he has been getting a lot of criticism, Dr. Kim may be doing something right. Still, he could wait a bit longer for the ‘after’ photos, just to avoid all the controversy.

“Okay dr Kim, imma need you to turn yourself in now,” one TikTok comment read, while another person read “I feel like Dr Kim’s office is in a dark abandoned alley.” But you know what they say, even negative publicity is good publicity.
