Microneedling Needle Comparison: Cartridges, Multi-Pin, and Nano Needles Explained

How to Compare Microneedling Needle Systems: Configuration, Needle Count, and Compatibility

Introduction

Microneedling needles are the precision components that determine how a microneedling system performs. They are not a single category: professional needle systems differ in structure, needle count, gauge, and the equipment they work with.

The main categories are microneedling pen cartridges, crystal multi needles, nanosoft needles, and traditional mesotherapy needles. Choosing between them requires comparing needle configuration, application method, and device compatibility.

At Deenora Beauty, we supply the complete needle system range — pen cartridges, multi-pin needles, nano needle systems, and mesotherapy needles — so professionals can build a system matched to their workflow.


5 Pin vs 9 Pin Needles: Which Configuration Should You Choose?

Needle count is the most visible difference between microneedling cartridges. It affects coverage, pressure distribution, and application feel.

Needle Count Configuration Typical Characteristics Common Use Context
3 Pin Three fine needles Precision-focused, small contact area Fine, targeted application
5 Pin Five needles Balanced coverage and control Standard multi-point application
9 Pin Nine needles Wider coverage, more contact points Broader treatment areas
12 Pin Twelve needles Higher density, smoother pressure spread General face and body application
16–18 Pin Sixteen to eighteen needles Highest density in pen cartridges, gentler per-needle pressure Full-face professional sessions
36 Pin Thirty-six needles Very high density Specialized high-density protocols

Summary: More needles spread pressure across a larger area, which generally makes application gentler per needle; fewer needles concentrate the contact area, which suits precision-focused work. The best configuration depends on the application area, device platform, and professional preference.


The Four Main Categories of Microneedling Needles

Category Comparison Table

Category Needle Structure Application Method Compatible Equipment Typical Configurations
Microneedling Pen Cartridges Multiple vertically moving needles in a sealed cartridge Micro-channel creation via motorized pen Electric microneedling pens (e.g. Dr. Pen A11, M8S, M8) 12 / 16 / 18 pin
Crystal Multi Needles Multiple fine needles arranged together Multi-point application Mesotherapy injectors, manual techniques 3 / 5 / 9 pin
Nanosoft Needles Ultra-fine multi-point structure Fine, superficial application Syringe, manual application Nano 3 Pin / Nano 4 Pin
Mesotherapy Needles Single needle Precise single-point application Syringe 30G / 32G / 34G

Microneedling Pen Cartridges

Pen cartridges attach to electric microneedling pens and move vertically during operation. They are the standard component for device-based microneedling.

Key characteristics:

  • Multiple needle points (commonly 12, 16, or 18 pins)
  • Disposable, sterile single-use design
  • Vertical needle movement driven by the device
  • Anti-backflow cartridge designs in newer models (e.g. A11, M8S)

Newer Dr. Pen cartridges use finer needles (0.18 mm tips compared with 0.25 mm in older designs) for improved comfort and precision. See the Dr. Pen compatible cartridges at Deenora Beauty.

Crystal Multi Needles

Crystal Multi Needles use multiple fine needles arranged in one cartridge, designed for multi-point application with mesotherapy-style workflows.

Available configurations at Deenora Beauty:

  • Crystal 3 Pin — precision-focused
  • Crystal 5 Pin — balanced coverage and control
  • Crystal 9 Pin — wider coverage

Crystal Multi Needles are commonly used with mesotherapy injectors or manual application techniques. Browse the Crystal Multi Needles collection.

Nanosoft Needles

Nanosoft needles feature ultra-fine multi-point structures designed for superficial, gentle application.

Available options:

  • Nanosoft 3 Pin — compact contact area
  • Nanosoft 4 Pin — slightly broader pattern, increased stability

Nanosoft needles are selected for fine, superficial aesthetic application where gentleness matters.

Mesotherapy Needles

Traditional mesotherapy needles are single-needle systems (30G, 32G, 34G) used for precise single-point injection. They provide maximum control over individual application points and are commonly associated with mesotherapy workflows.


Nano Needling vs Microneedling: Understanding the Difference

"Nano needling" and "microneedling" are often used interchangeably, but they refer to different needle systems.

Aspect Microneedling Nano Needling
Needle structure Standard multi-pin or pen cartridges Ultra-fine (nano) needle structures
Application depth Adjustable, broader range Shallow, superficial focus
Device context Electric pens, rollers, injectors Nano cartridges, nano patches, infusion systems
Typical use Broad professional service range Fine, gentle application; product absorption focus

Summary: Nano needling is a specialized subset of microneedling technology characterized by ultra-fine needle structures. The choice between standard microneedling and nano systems depends on the application depth and gentleness required by the service design.

Nano-related products — including nano patches and nano infusion systems — have become a popular consumer category. For professional practices, nano needle cartridges (such as Nanosoft 3 Pin / 4 Pin) provide a professional-grade option within this category.


Microneedling Cartridges vs Mesotherapy Needles: Key Differences

A common source of confusion is the difference between pen cartridges and mesotherapy needles.

Aspect Microneedling Cartridge Mesotherapy Needle
Primary function Micro-channel creation Precise product delivery
Needle structure Multiple vertical needles Single needle
Equipment Electric microneedling pen Syringe or injector
Example Dr. Pen 12/16/18-pin cartridge 30G / 32G / 34G needle

Summary: Pen cartridges create controlled micro-channels as part of device-based microneedling. Mesotherapy needles are used for precise product delivery in injection workflows. They are different categories and should not be confused when selecting products.


Device and Needle Compatibility Matrix

Matching the needle system to the device platform is essential.

Device Platform Compatible Needle Systems Examples
Electric microneedling pen Pen cartridges matching the connector type Dr. Pen A11/M8S/M8 cartridges
Mesotherapy injector Multi-pin injection needles Crystal 3/5/9 Pin
Syringe / manual Nanosoft needles, mesotherapy needles Nano 3/4 Pin, 30G/32G/34G
Dermal roller Fixed roller needle head (non-replaceable) Roller-specific design

Always verify cartridge compatibility with your device before purchasing. See Device & Needle Selection for the full selection framework.


Needle Gauge and Length: A Professional Reference

Beyond needle count, gauge and length are the specifications that define how a needle interacts with the skin.

Needle Gauge

Gauge (G) refers to needle thickness. In aesthetic practice:

  • 34G — the finest common gauge, associated with delicate application
  • 32G — a widely used mid-range gauge for precise injection
  • 30G — a slightly thicker gauge, commonly used in mesotherapy

Finer gauges generally create smaller contact points, which is why they are associated with more delicate application work.

Needle Tip Size in Pen Cartridges

Dr. Pen cartridge technology has evolved from 0.25 mm tips to finer 0.18 mm tips in newer cartridge generations. Finer tips are associated with improved comfort during application. Newer cartridges also include anti-backflow designs that help prevent liquid from flowing back into the device when serum is applied to the needle — relevant for professionals who apply products directly onto the cartridge.

Sterility and Packaging

Professional needle products should use sterile single-use packaging. This is a non-negotiable consideration for professional practice:

  • Single-use design prevents cross-contamination
  • Sterile packaging maintains product integrity until use
  • Consistent manufacturing supports predictable performance

How to Choose the Right Microneedling Needle

1. Consider Your Application Method

  • Electric pen → pen cartridges
  • Mesotherapy injector → crystal multi needles
  • Syringe or manual → nanosoft or mesotherapy needles

2. Consider Needle Configuration

  • 3 Pin — precision-focused applications
  • 5 Pin — balanced coverage and control
  • 9 Pin — wider coverage requirements
  • 12/16/18 Pin — high-density professional sessions

3. Consider Gauge and Quality

  • Finer gauges (e.g. 34G) are associated with more delicate application
  • Professional products should use sterile single-use packaging
  • Manufacturing consistency matters for predictable performance

4. Consider Supply Reliability

  • Cartridge availability for your device
  • Consistent reorder options for ongoing practice

How Cartridge Technology Has Evolved

Microneedling cartridge design continues to develop alongside device technology.

From Fixed Rollers to Precision Cartridges

Early microneedling tools used fixed needle arrangements. Modern pen cartridges introduced replaceable, disposable designs that attach to electric devices, enabling:

  • Adjustable application depth
  • Higher needle counts in a single cartridge
  • Sterile single-use hygiene standards

Newer Cartridge Generations

Recent developments in Dr. Pen cartridges include:

  • Finer tips — 0.18 mm tips compared with 0.25 mm in older designs
  • Anti-backflow structures — reduce liquid flow-back into the device when serum is applied to the needle
  • Curved and wavy cartridge edges — designed to improve serum spread during application (found on models such as A11, M8S, A9, A10, and A8S)

These developments reflect the industry's focus on application comfort, hygiene, and consistent performance.
