RF Microneedling Cartridges Explained: 12P vs 24P vs 40P vs Nano
Treatment cartridges are a core part of a professional RF microneedling platform. They affect treatment coverage, precision, workflow and ongoing operating cost, yet many clinics focus on the machine itself and treat cartridge selection as a secondary detail.
Understanding the differences between 12P, 24P, 40P and Nano options can help clinics evaluate whether a system fits their face-and-body treatment workflow and long-term consumable planning.
There is no single “best” RF microneedling cartridge. Smaller arrays can provide more focused coverage, while larger arrays can improve treatment efficiency on suitable areas. Nano tips serve a different surface-oriented role. The right choice depends on the treatment area, device design and professional protocol.
Professional RF microneedling systems may use different cartridge configurations for precision, coverage and surface treatment workflows.
1. What Do 12P, 24P and 40P Mean?
The number usually refers to the needle or electrode array used in the treatment cartridge. A 12P cartridge contains fewer treatment points than a 24P or 40P cartridge, which can influence treatment coverage and precision.
However, clinics should not assume that all cartridges with the same number are identical. Needle geometry, spacing, insulation, depth capability and RF delivery design can differ between manufacturers and machine models.
2. 12P Cartridge: Precision-Oriented Treatment
A smaller 12P array can be useful when the operator wants more focused treatment placement or is working on a relatively small treatment area.
From a workflow perspective, the advantage is precision rather than maximum coverage. Clinics should confirm the intended use of the 12P cartridge for the exact machine they are purchasing.
3. 24P Cartridge: Balanced Coverage
A 24P configuration can provide a balance between focused treatment and wider coverage. This type of cartridge may fit clinics that want flexibility across several professional facial protocols.
As with every treatment tip, the actual application depends on the machine design, treatment settings, professional assessment and manufacturer instructions.
4. 40P Cartridge: Larger Treatment Coverage
A 40P cartridge generally provides a larger treatment array, which can help improve coverage efficiency on appropriate treatment areas.
For clinics with higher treatment volume or broader face-and-body workflows, larger cartridge options can be useful — but treatment speed should never replace careful parameter selection and correct technique.
5. What Is a Nano Cartridge?
Nano-style tips are typically positioned as surface-treatment options rather than traditional penetrating microneedle cartridges.
The exact construction and intended use can vary significantly by manufacturer, so clinics should review the machine documentation before describing or using a Nano mode.
Quick Cartridge Comparison
| Cartridge | General Role | Clinic Consideration |
|---|---|---|
| 12P | Focused coverage | Useful where more precise placement is required |
| 24P | Balanced coverage | Flexible professional treatment workflow |
| 40P | Wider coverage | Can improve coverage efficiency on appropriate areas |
| Nano | Surface treatment | Confirm exact function with the machine manufacturer |
6. Cartridge Cost Matters More Than Many Buyers Expect
RF microneedling cartridges are ongoing consumables. A low machine purchase price can be less attractive if compatible cartridges are expensive, frequently out of stock or difficult to ship to your market.
Before purchasing equipment, ask the supplier for current cartridge pricing, minimum order quantities, available models, packaging and estimated delivery times.
7. Single-Use Cartridges and Infection Control
Treatment cartridges should be handled according to the manufacturer’s instructions and the clinic’s infection-control procedures.
The U.S. FDA advises health care providers not to reuse microneedling cartridges or use one cartridge on more than one patient because of the potential risk of infection.
8. Questions to Ask Before Choosing a Machine
- Which cartridge types are included with the machine?
- Are 12P, 24P, 40P and Nano options all compatible?
- How much does each replacement cartridge cost?
- Are the cartridges individually packaged?
- What is the normal consumable lead time?
- Can the supplier provide cartridges several years after purchase?
- Which cartridge is intended for each treatment mode?
- Does the supplier provide cartridge and parameter training?

Which RF microneedling cartridge is best?
There is no universal best cartridge. Selection depends on the treatment area, machine design, treatment objectives and professional protocol.
What is the difference between 12P and 40P?
A 12P cartridge generally provides a smaller treatment array, while a 40P cartridge provides broader coverage. Exact construction varies by machine.
Can RF microneedling cartridges be reused?
Clinics should follow the manufacturer’s instructions. The FDA advises health care providers not to reuse microneedling cartridges or share one cartridge between patients.
Why is cartridge supply important when buying a machine?
Because cartridges are ongoing consumables. Poor availability can interrupt treatments and increase operating costs.
