Everyone is different. I’m 62, short waisted and have a lot of fat (43 inches) in mid section and waist. My experience was initial pain in mid section first few minutes…breathe thru it. Abdomen and thighs were easier. Rubbing alcohol removed the markings made from the permanent marker. I purchased from Amazon Earth’s Daughter aloe Vera gel to help with the itching. Uncomfortable to sit and lay first 24 hours, took 2 Tylenol 500mg to sleep. Don’t hesitate to have this treatment done at Young Medical Spa. Denise was amazing and the rest of the staff are wonderful. Overall, I lost a few pounds my first 5 days and my thighs don’t rub together! Gave up diet soda, cake, cookies and candy. Anxious to see my positive results in 30 days.
