I had calf botox treatment around August last year. It was a dermatology clinic near Seolleung Station, and I went because I saw an event on a place called Goodoc, so I do not remember the name exactly The only things I remember are that the interior was clean and impressively nice. I remember the price was 9.9 plus tax separately.
It hurt more than I expected, and above all, the effect was excellent for me. But as they told me at the clinic, it lasted exactly 3 months! Looking at my slimmer calves, I thought it would last forever, but they did return a little toward their original shape. I would do it again, and it is a procedure with a big self-satisfaction factor, so I am very satisfied.
