I've been hearing about Dermafile lately as an option to use instead of Microdermabrasion machines, that it's more holistic way and cheaper to use as a service. I definitely don't have the money or space for the fancy machines so I am wondering if anyone on here really like using the Dermafile and what are the pros and cons about using it? Is it hard to judge how hard you are using the tool on the client's face? Would love to hear from estheticians that are using it..before I purchase one. Hoping to see it at a booth when I go to the Face and Body show this Aug.
