In vivo histological evaluation of non-insulated microneedle radiofrequency applicator with novel fractionated pulse mode.

Abstract

INTRODUCTION Microneedle radiofrequency is a novel method that allows non-thermal penetration of the epidermis followed by RF coagulation in selected depth of the dermis surrounded by zone of non-coagulative volumetric heating. The first generation of Microneedle RF applicators used insulated needles. These treatments were limited by a few factors… (More)
