I had it done 2 years ago. To sum it up, it hurts and doesn't seem to be effective . I had a lot of fat on my abdomen, so it cost about 1.5 million won. The bruises seem to have lasted for about 2 weeks or so and it doesn't have a dramatic effect like diarrhea. They say you have to diet along with the injection, but I'm not good at dieting, so it really didn't work. I don't think it's much different from just dieting to lose weight. They say it's more effective if you combine diet and exercise, but if you're not confident, I think just acupressure would be better.
