I had 100 shots of Ice Shrink for 55,000 won. I'm a man in my late 20s, and my eyelids felt like they were sagging, so I asked them to focus on the upper eyelid area. They worked well on the area I wanted and were kind. The director honestly told me that Ice Shrink probably wouldn't have a very big effect on me.
The manager actually recommended non-incisional eye correction if that was the issue. Shrinking didn't hurt that much, but it felt stingy and prickly.
