I have been trying the RF to reduce the belly. It has been reduced from 33" to 31.5" now for 2 months.
My beautician make use of the RF machine together with the aglae slimming gel. I feel a little hot but confortable. After that, they wrap my belly with the cold bandage. I do it twice a week. The price is about $340-$380 per times(20mins.)
I'm not sure if the price is cheap or notas I haven't made the comparison. It costs around $340-$380/20mins(depends on now many times of the course; of course, the most is the cheapest).
You can choose belly, arm or thighs or hip depends on your situation is. If you need to add the cold bandage, it's $100 only.
