I dont agree with either of these statements.
First, I am living proof that facial self electrolysis can be done safely, and effectively. I listened to a lot of comments similar to this while doing so, and every one of them was incorrect.
Second, Apilus/Dectro machines are no more safe or effective than any other brand of epilator. Tehy all kill hair safely and effectively. I actually DO use an Apilus Xcell in my practise and I would be the first to tell you that the one thing holding back good treatments is a poor reliability record and lack of support. The person who goes out of their way to choose a practitioner by manufacturer of their machine, is a fool.
Finally, galvanic is EXTREMELY slow to progress, actually too slow for descent DIY work. I regularly recommend blend treatments for DIY because THEY CAN be done safely and effectively and in a timely manner. There is zero advantage to spending all that time and discomfort waiting for galvanic treatments and most who do try this route, generally get frustrated and quit before completion.
