This does not mean, however, that you can simply buy a roller and start using it as you like.
Right after I ordered a roller for the first time, I began researching as much as I could about it. What I discovered is that there is mainly a lot of misinformation and contradicting answers on the internet regarding even the most basic questions such as, where on the body the roller can or cannot be used, how often it should be used (how long you need to wait between treatments), how long a it lasts, how often to sterilize it, and so on.
It took me a long time but I was finally able to come up with answers to most if not all of these questions.
The information on this blog is based on other sites as well as my own experience with the dr.roller, feel free to browse the various posts but remember to always be critical about what you read online! The ground rule is: if the website also sells the rollers - be extra doubtful about the information it gives!
