Fractional RF in Skin Rejuvenation: Which Depth Works Best?
Summary
Fractional RF (Radio Frequency) delivers controlled heat energy through microneedles into the dermis, stimulating collagen production and tightening skin. The treatment depth determines how effectively specific skin issues—like wrinkles, acne scars, or sagging—are addressed. Selecting the right penetration level ensures both safety and results, making it one of the most customizable rejuvenation methods available today.
Understanding RF Depths and Their Effects
| Treatment Depth | Primary Target | Key Benefits | Recommended Settings |
|---|---|---|---|
| 0.5–1.0 mm | Epidermis & Upper Dermis | Improves fine lines, refines pores, enhances texture | Gentle mode, suitable for sensitive or thin skin |
| 1.5–2.0 mm | Mid Dermis | Reduces wrinkles and shallow scars | Moderate energy for facial firming and rejuvenation |
| 2.5–3.5 mm | Deep Dermis & Subcutaneous Layer | Lifts sagging areas, tightens jawline, stimulates deep collagen | Higher energy mode for thick skin or mature clients |
How to Choose the Right Depth
The ideal fractional RF depth depends on:
-
Skin Type: Thinner skin (eyes, neck) benefits from shallow penetration.
-
Treatment Goals: Deep wrinkles or laxity require deeper RF delivery.
-
Client Comfort: Adjustable microneedle lengths allow customized comfort and results.
Professional devices like the NewBelle RF Wrinkle Removal Machine with Cold Hammer & Microneedle RF enable practitioners to switch depths and energy levels easily, ensuring every client receives a truly personalized treatment.
