I had severe dark circles since I was young, so it was stressful . I had severe dark circles because of pigmentation + muscle 'visualization of blood vessels. The hospital said it couldn't be completely improved, but it would be better than before with fat grafting. The first month after the surgery, all the bruises and swelling disappeared, and the second month was somewhat effective. It seemed like it was the same, but from the 3rd month onwards... I just threw away my money . do something else
