I got it for the first time at a factory-type dermatology clinic in Gangnam Station, and it hurt so much that I resented the person who said it didn't hurt in mode... The more the fever rises, the more it hurts... While I was doing it, the doctor grabbed my wrist and told me it was so painful lol. I've heard very little. If you look at the reviews, there are a lot of people who are bruised so badly that it looks like they've been hit. It's definitely effective, and it hurts... I heard that it hurts, but the effect is as good as it hurts. I've heard a lot of people say they lost weight after taking In Mode. I feel a little proud every time haha -Summary- Satisfaction ★★★★★ Doctor for re-operation: ★★★★☆ (Too painful) Degree of pain: ★*100!!!
