Initially, I felt as if my stomach got sucked into the vacuum. However, after a while, I began to feel more relaxed and was able to use my cell phone, update news, and chat with my friends until the treatment was over. Undergoing coolsculpting at F Clinic was a good experience for me in that they have two machines, so the treatment time was shorter since multiple areas can be treated at the same time. After treatment, my skin was really red and cold. I even thought to myself that this is really the technique of eliminating fats by freezing. There was also a staff who massaged the treatment area and the skin redness gradually disappeared after 5-10 minutes of treatment. After one month, I could clearly see that the treatment area was significantly reduced.
