Of course, there may be kebake, but there are people who say that the pain is severe while opening your eyes . It went away quickly , usually when I wake up in the morning, my eyes are very swollen, but that was the case. I did it at the end of December last year, so I don't know how much more the swelling will go down, but after the entire swelling has gone down in a month, the size of the double eyelids doesn't get thinner and stays constant for two months. I'm pretty, and it was a bonus that it did well.. I'm very, very satisfied with the past few months, so I proudly recommended it to Changu who is recognizing the hospital..
