48 patents in this list
Updated:
Radiofrequency (RF) devices for skin rejuvenation operate at frequencies between 30-90 GHz, delivering power flux densities of 0.5-15 mW/cm². When applied to tissue, these electromagnetic waves generate controlled thermal effects at depths of 3mm or greater, targeting the dermis where collagen synthesis and remodeling occur.
The fundamental challenge lies in delivering sufficient RF energy to stimulate beneficial tissue responses while maintaining precise temperature control to prevent thermal damage to surrounding structures.
This page brings together solutions from recent research—including capacitive coupling electrode designs, impedance matching circuits, integrated cooling protocols, and synchronized multi-wavelength systems. These and other approaches focus on optimizing energy delivery while maintaining safety and comfort during treatment.
