Radiofrequency treatments: what can we expect?

Area of Science:

• Aesthetic Medicine
• Biophysics
• Dermatology

Background:

• Radiofrequency (RF) therapy is a popular non-ablative procedure for treating facial and body skin laxity.
• It functions as a physical biostimulation method, increasing tissue temperature via electromagnetic waves.
• Existing RF devices vary significantly in energy, wavelengths, and handpiece design, with some lacking fully defined protocols.

Purpose of the Study:

• To clarify aspects of radiofrequency therapy, including its underlying physics.
• To explain the mechanism of action for RF treatments.
• To provide guidance on optimizing RF therapy protocols for aesthetic medicine.

Main Methods:

• Review of the physics of electromagnetic waves in relation to RF applications (capacitive vs. resistive).
• Discussion of the therapeutic effects, including thermal damage and the terms "non-surgical" and "non-ablative."
• Analysis of protocol optimization based on device characteristics and patient-specific factors.

Main Results:

• Electromagnetic waves in RF are transversal, influencing energy distribution in capacitive (monopolar) and resistive (bipolar/multipolar) applications.
• The concept of thermal damage as the sole therapeutic effect requires nuanced discussion.
• Effective protocols depend on understanding individual device capabilities and limitations.

Conclusions:

• Radiofrequency therapy offers biostimulation for immediate and long-term skin rejuvenation.
• Optimized protocols are essential for safe, effective, and useful medical treatments.
• A thorough understanding of RF device physics and limitations is mandatory for practitioners.
