I went to Dr. Kristina Masuga's office and discussed with her about fat freezing. I have done multiple areas. I have very sensitive skin and was concerned about pain and bruising. I was pleasantly surprised that there was minimal pain, that went away after a few minutes, and no bruising. My abdomen, I did 6 areas, and I also did 4 areas on my chin/neck. I was so very happy with the results, and would and will do more treatments. Great results with minimal discomfort and no dieting or exercise... can't beat that!
