Choosing the right microcannula means balancing gauge, length, product characteristics, treatment area and clinical technique. This guide explains the Precision32 dermal filler microcannula range for appropriately trained healthcare professionals.
What is a microcannula?
A microcannula is a flexible, blunt-ended device with a lateral exit port near the tip. In aesthetic practice, microcannulas may be used to deliver compatible dermal fillers and other injectable products, subject to the product instructions for use and the clinician’s judgement.
Unlike a conventional sharp needle, a blunt-tip microcannula normally requires an entry point created with an appropriate introducer. Device selection should always reflect the intended treatment, tissue plane and properties of the product being delivered.
Precision32 microcannula sizes
| Gauge | Available lengths | Selection considerations |
|---|---|---|
| 22G | 50mm, 70mm | Wider internal lumen and longer treatment pathways. |
| 23G | 50mm, 70mm | A balance of lumen size, control and reach. |
| 25G | 40mm, 50mm | A versatile option where a smaller external diameter is preferred. |
| 27G | 40mm | A fine option for appropriately selected products and techniques. |
The appropriate gauge and length cannot be selected by treatment area alone. Clinicians should also consider the viscosity and rheology of the product, required depth, access point, pathway and manufacturer instructions.
Understanding microcannula gauge
Gauge describes the external diameter of the device. A lower gauge number indicates a wider cannula. The usable internal lumen is also influenced by wall thickness. Precision32 microcannulas use an ultra-thin-wall design to provide a wider internal lumen without increasing the external gauge.
Choosing microcannula length
Length affects reach from the entry point and the clinician’s ability to access the planned treatment pathway. Precision32 offers 40mm, 50mm and 70mm options. A shorter cannula may suit a more localised pathway, while a longer device may reduce the need for multiple access points in appropriately selected cases.
Precision32 design features
- Rounded bullet tip: Designed for controlled passage through tissue planes.
- Near-tip lateral exit port: Supports precise product delivery close to the cannula tip.
- Ultra-thin wall: Creates a wider internal lumen than a standard-wall device of the same external gauge.
- Japanese stainless steel: Selected for consistent device construction.
- Proprietary surface treatment: Supports smooth gliding.
- Side-wall markings and graduations: Help clinicians monitor orientation and insertion depth.
- Luer lock hub: Provides a secure connection to compatible syringes.
Microcannula or needle?
Neither device is appropriate for every injection. The choice depends on the product, treatment objective, anatomy, depth and technique. Needles provide a sharp entry and may be selected for highly localised placement. Microcannulas provide a blunt tip, flexibility and a lateral exit port. Clinicians should choose the device that best matches the procedure and product instructions.
Microcannulas for suspension products
The near-tip exit port and ultra-thin-wall design are intended to support smooth delivery with low extrusion force. When using suspension products, including products containing larger particulates, clinicians must follow the manufacturer’s preparation and administration instructions and choose a compatible device.
