Dual Frequencies: Operates at 1 MHz and 2 MHz bipolar radiofrequency, allowing coagulation at multiple tissue depths and intensities.

Dual Pulse Wave: Enhances treatment customization for improved precision and patient comfort.

Adjustable Settings: Easily tailor parameters to meet different clinical needs, optimizing treatment outcomes.

Dual-Frequency Gold RF Microneedling

Technical Training Guide for Physicians

1. System Overview

This system is a dual-frequency bipolar gold RF microneedling platform designed for controlled dermal thermal coagulation and collagen remodeling. It combines mechanical microneedle penetration with precisely delivered radiofrequency energy, allowing targeted treatment at different skin depths with high safety and repeatability.

2. Display & Control System

15.6-inch Android touch screen with a resolution of 1920 × 1080 px

Intuitive interface for parameter adjustment, protocol selection, and real-time monitoring

Supports manual and automatic operation modes to accommodate different clinical workflows

3. RF Technology

Dual-frequency bipolar RF: 1 MHz and 2 MHz

2 MHz: optimized for superficial and mid-dermal heating

1 MHz: deeper tissue penetration for volumetric dermal heating

RF output range: 1–12 W, adjustable in 1 W increments

Pulse width adjustable from 1–100 ms, allowing precise thermal control

4. Microneedle Design & Material

Pure gold-plated microneedles with gold purity ≥ 99.95%

Gold coating enhances biocompatibility, conductivity, and corrosion resistance

Needle spacing: 1.5 mm, designed for uniform energy distribution and controlled tissue response

5. Treatment Depth & Layered Therapy

Adjustable needle penetration depth:

Standard range: 0.5–3.5 mm

Extended depth (selected cartridges): up to 7.0 mm

Layered treatment capability allows RF delivery at up to 5 depth levels in a single pass, enabling multi-level dermal remodeling

Five-layer insertion cycle completed in 0.2 seconds, ensuring efficient and stable energy delivery

6. Vacuum vs Non-Vacuum Treatment Heads

1.1.1 Vacuum Treatment Heads

Available with 3 vacuum levels (1 / 2 / 3)

Vacuum assists in stabilizing tissue, improving needle penetration consistency, and reducing epidermal resistance

Suitable for areas requiring enhanced contact and uniform depth

1.1.2 Non-Vacuum Treatment Heads

Vacuum function OFF

Preferred for sensitive areas or practitioners seeking maximum manual control

7. Treatment Head Configurations

The system supports multiple cartridge types to address different clinical needs:

VI Series: Vacuum + layered RF delivery

VNI Series: Vacuum without layered RF

NVI / NVNI Series: Non-vacuum options with or without layered treatment

Needle counts and treatment areas vary (10 / 25 / 49 pins) to adapt to facial and body indications

Each cartridge is designed for up to 1200 shots, ensuring consistent performance during treatment sessions.

8. Operating Modes

Continuous Mode: steady RF output for uniform thermal coagulation

Pulse Mode: controlled RF bursts for enhanced thermal precision

Automatic timing options: 0.3 s / 0.5 s / 0.8 s / 1.0 s / 1.5 s / 2.0 s

Manual mode for full physician control during advanced treatments

9. Clinical Application Considerations

This system is suitable for treatments requiring:

Controlled dermal coagulation

Collagen denaturation and remodeling

Skin tightening and texture improvement

Parameter selection should be based on treatment area, skin thickness, indication, and patient tolerance. Gradual parameter escalation is recommended.
