I got them at Galaxy Plastic Surgery because they said I could get 5 petit procedures for 100,000 won. I think the cost-effectiveness for double chin skin botox, forehead, and square jaw is good. When I was applying the anesthetic cream, everyone was watching, so I was a little? embarrassed, but the effects were good and I'm satisfied. Oh , I keep getting them done periodically for my forehead, forehead, and double chin, but I want to try other petit procedures in a few months!!
