Permanent Hair Removal With Home Electrolysis.Needles, Epilators, Holders.

How can we have electrical stimulation therapy without electrolysis?

I have read a lot about the benefits of using electrical stimulation therapy and how safe it is, but I don’t understand how it can’t be causing at least some degree of electrolysis to damage the tissue in the body. They use electrical stimulation for childbirth and show off its safety, but I think they use the same electrical stimulation to permanently damage hair follicles for hair removal. Does anyone know how this works or what the difference is? Thanks
