Dermadart is unique because its patent-pending technology not only does away with any motor (instead using an electromagnet linear drive), it also is the first and only dermaneedling device to feature a burst mode meaning it can deliver preset pulse numbers and even individual pulses for ultimate precision and a very low duty cycle. And with a cleverly designed of the needle cartridge featuring dual-powered retraction, the Dermadart can be moved along the skin while it is operating.
