I usually tolerate pain well and there is an additional charge of 100,000 won for sleeping, so why bother? I wanted to do the treatment without sleep. It was 400 shots excluding the forehead, and it took about 40 minutes after applying anesthetic ointment. What I wanted was for my double chin and jaw line to become smooth. Actually, I had a bulge above my nasolabial fold, so I was debating whether or not to tell the doctor, but my nasolabial fold said there was no effect, so I just focused on my jaw line. A month later? From now on, the lines are strangely thin? I was satisfied because I felt like my double chin had improved, but now, 6 months later, it feels saggy again and I'm contemplating whether I should just do a thread lift or sleep again.
