🔬 The Core of RF Technology:
Definition and Key Advantages
Radio Frequency (RF) refers to high-frequency alternating electromagnetic waves within the range of 300 kHz to 300 GHz. In medical aesthetics, the commonly used frequency range is typically 0.4-40.68 MHz. Its core value lies in its “color-blind” energy characteristics:
– Controllable Penetration Depth: RF can reach from the deep dermis to the SMAS fascial layer (4-20 mm), breaking through the penetration limitations that laser technologies face due to skin pigmentation.
✅ Ideal Candidates:
– Those with mild to moderate skin laxity (e.g., nasolabial folds, undefined jawline)
– Individuals seeking to improve dynamic wrinkles/static fine lines
– Those desiring non-invasive tightening and lifting effects
– Individuals needing maintenance post-procedure (e.g., to enhance effects combined with light therapy or fillers)

Clinical Effects and Risk Management: Data-Driven Rational Understanding
1. Treatment Efficacy Duration and Course Design
| Device Type | Onset of Effect | Peak Effect | Duration of Effect | Recommended Course |
| Medical Monopolar RF | Immediate | 3-4 months | 1-3 years | 3-6 sessions, 1-month intervals |
| Home Multipolar RF | 2-4 weeks | 6-8 weeks | 3-6 months | 2-3 times weekly for maintenance |
