It didn't work... It didn't hurt and my skin bruises easily, so it didn't bruise either, which was good, but the effect wasn't great...ㅠㅠ My relative who went with me said the effect was pretty good. Maybe it's because I have a lot of fat on my face, but my round face only received one session and the effect was good... The teacher is really meticulous, so I highly recommend it!!!!
