RF microneedling is a fractional radiofrequency procedure that uses insulated needles to deliver RF energy directly into the dermis, creating controlled thermal injury and triggering collagen synthesis and remodeling. Unlike surface-only RF or non-insulated microneedling, RF microneedling concentrates energy at depth—typically 0.5 to 3.5 mm below the epidermis—while the needle shaft itself is insulated to protect the skin surface, minimizing downtime and epidermal damage.
