At the end of July 2023, I had a Juveluc booster injected into my neck and developed severe nodules. After being overseas, I came back at the end of October for treatment because of this. They said it would be resolved with forma and saline injections, but after a week, when there was little effect, they gave me some kind of injection while shining a light. I didn't know what the injection was. Then I went abroad again, but instead of getting better, I began to lose weight, the skin around me became strange, and my color changed, so I am now back in Korea.
If you know the best treatment for this phenomenon, please recommend it.
