XERF’s dual-frequency radiofrequency (RF) technology improves collagen stimulation by delivering two different frequencies (6.78 MHz and 2 MHz) to target multiple skin depths simultaneously. This provides a more comprehensive and robust heating effect compared to single-frequency devices, which typically address only a single layer of tissue.
How each frequency targets different depths
- 6.78 MHz (Higher Frequency): This frequency primarily targets the more superficial to mid-dermal layers of the skin, where fine lines, wrinkles, and changes in skin texture are most visible. Heating these layers causes immediate tightening of existing collagen fibers and triggers the production of new collagen and elastin in the dermis.
- 2 MHz (Lower Frequency): This frequency penetrates deeper into the subcutaneous fat and the Superficial Musculoaponeurotic System (SMAS), a foundational tissue layer that is also addressed in surgical facelifts. Heating this deeper layer helps remodel and tighten the underlying support structure of the skin, providing a significant lifting effect.
By delivering energy to shallow, middle, and deep layers simultaneously, dual-frequency RF creates what is known as volumetric heating. This comprehensive and uniform heating of the entire dermal thickness stimulates a larger population of fibroblasts across different depths. The result is a more robust and widespread production of new collagen, leading to superior and more natural-looking skin tightening and rejuvenation compared to treatments that heat only a single, specific layer.
Benefits of combining dual frequencies
The use of dual frequencies provides several advantages for enhancing collagen stimulation:
- Layered collagen remodeling: By delivering heat to both the superficial and deeper layers, XERF stimulates new collagen growth throughout the skin’s architecture, not just in a single plane. This creates a stronger, longer-lasting tightening and lifting effect.
- Comprehensive tightening: Superficial heating improves the appearance of surface wrinkles and texture, while deep heating tightens the underlying support structure. Together, they produce a comprehensive rejuvenation of the skin.
- Customizable treatment: The dual-frequency technology allows practitioners to customize the treatment by adjusting energy levels and depth settings to target a patient’s specific needs. For example, more energy can be delivered to the deeper layers to address sagging jowls, while more superficial energy can improve fine lines around the eyes.
