Non-invasive facial wrinkle reduction by means of radiofrequency tissue heating is frequently used as an alternative to invasive procedures. Despite its widespread use, there is a lack of published numerical models that would allow an in-depth understanding of tissue heating in specific layers of the body. We constructed a numerical model of non-invasive radiofrequency tissue heating using a CryoDerm device and evaluated the use of the device on facial wrinkles in a pilot clinical study. Our numerical model showed pronounced heating of the deeper tissue layers, with only partial heating of upper layers. The clinical study showed immediate periorbital and nasolabial wrinkle improvement, and great patient satisfaction with a painless therapy.

Key words: rhytid, wrinkle, non-invasive procedure.
