I'll teach you how to check the blacklist!
 1. 2011 Plastic Surgery Clinics that Receive Multiple Dispute Resolution Applications -> If you type this into Google, you can see the status of applications for clinics that receive multiple plastic surgery dispute resolution applications as surveyed by the Korea Consumer Agency in 2011. The data is from 2011, so it's a bit outdated, but it's worth reference! There is no latest data ㅠㅠ Unfortunately
 2. Use Google and Seongyesa to search for a combination of 00 plastic surgery/000 director + 00 surgery + black/reoperation/side effects!
 3. Refer to the plastic surgery blacklist! (I found this while Googling)

 4. Skip the harsh hospitals by looking through the premium reviews at Seongyesa Hospital!
 
I think it would be a good idea to roughly use this method.
 
You can see the rulings related to medical lawsuits by searching for 'plastic surgery', 'nose surgery', 'plastic surgery clinic', etc. at the 'Korea Court Electronic Civil Service Center', but they are all anonymous anyway (Director A, Clinic B, etc.) ) Not much help!
