I have a Dermapen HOME and a professional Dermapen device.

Why do I have to have a separate User Account for each one?

If you have a Professional DermapenWorld device and a personal DermapenWorld device (Dermapen HOME), you must have two separate User Accounts as there is a different User experience for each type of device. 

Users in this case scenario are quite limited. If this affects you and you have concerns please Contact Us at www.dermapenworld.com/contact-us
