I want to file a dermatology lawsuit. Is it possible?

Based solely on what you have shared, there is sufficient room to consider a dermatology lawsuit.

Medical institutions have a duty to specifically explain the foreseeable side effects, recovery period, and likelihood of occurrence prior to a procedure. In many cases, an explanation limited to "you may experience swelling for a few days" is unlikely to be considered as having fulfilled the duty to explain.

In particular, in past precedents, there have been dermatology lawsuit cases where the medical staff's breach of the duty of care was recognized when no consent form or sufficient explanation prior to the procedure could be confirmed, and there was a specialist's opinion that pigmentation occurred due to excessive procedures causing strong irritation to the skin.

Additionally, cosmetic skin procedures involve high expectations regarding results, and for areas that directly affect appearance such as the face, even temporary side effects are considered to cause significant mental distress and inconvenience in daily life.

Therefore, if your current symptoms are not improving in a short period and there were issues with the dermatology procedure or the explanation, it is necessary to specifically review whether you can hold them liable for damages through a dermatology lawsuit based on the related materials.
