To address the limitations of both modalities, patients were
treated with an RF device immediately before HA filler
injections. Specifically, the device used in the current
study delivers RF through an intradermal needle, thus creating
tunnel-like coagulation canals inside the dermis and
hypodermis. These canals theoretically act as protective
barriers against external oxygen radicals, while simultaneously
containing the injected HA filler and restricting
filler spread. This combined treatment may prolong the
duration of HA treatments and reduce the amount of HA
filler required for maintenance. Furthermore, treatment
with the RF device may also reduce wrinkles by inducing
dermal remodeling and tightening.
