Photon’s right. Face and belly skin don’t have the same makeup, would be a waste of product. I’ve seen women try it without any change. It is indicated for décolleté/upper chest in the thinner skin area though.
For belly, if you’re looking for skin tightening or collagen stimulation, microneedling and radio frequency are the better options. It will take several treatments, but you have to be realistic about what it can accomplish.
I’m in some diy aesthetics groups and mychway is recommended for professional grade rf machines. I don’t have any personal experience, but can search the groups if you want. For microneedling, Dr Pen or Derminator.
I’m going to include a pic I just grabbed from Reddit from someone who says they microneedled.
