What are the effects of traditional Korean medicine weight loss procedures?

I once saw results by losing weight with personalized herbal medicine for dieting.

At that time, I was prescribed herbal medicine to control appetite and prevent side effects, and I successfully lost weight by combining it with a diet. Considering the previous diets I tried a few times, I wondered whether managing localized fat was truly effective, and I strongly believed that overall weight loss would also reduce the size of specific areas. However, since some areas like the lower abdomen don't shrink as much as I expected, I am now becoming more interested in managing localized fat.

I remember there used to be a program at traditional Korean medicine clinics for managing localized obesity with acupuncture, but these days I see treatments like fat-dissolving herbal injections and medium-frequency electrical therapy. I'm curious about how effective these procedures are and how long it typically takes to see results.
