Beyond selecting the right product, the choice of delivery system—specifically the cannula—is critical for ensuring safety, minimizing downtime, and achieving natural-looking results.
This guide outlines is our suggestion for recommended cannula types and sizes for administering some of the most sought-after treatments today:
1. Hyaluronic Acid (HA) Fillers (e.g., Juvederm®, Restylane®)
-
Product Type: Standard HA Fillers for wrinkles and volume.
-
Recommended Cannula: 27Gx38,27Gx50mm length, blunt tip.
-
Why: The flexibility of a 27G cannula allows for smooth deposition of standard viscosity fillers. Longer lengths (e.g., 40mm) enable tunneling to treat larger areas like the mid-face cheeks with fewer entry points, reducing bruising.
-
Key Benefit: Reduced bruising and more even product distribution.
2. Collagen-Biostimulators (e.g., Sculptra®)
-
Product Type: Poly-L-lactic acid (PLLA) for gradual collagen production.
-
Recommended Cannula: 25Gx 50,25Gx70mm length, blunt tip.
-
Why: Sculptra requires deep dermal or subdermal placement. A thicker, longer cannula (25G) provides the necessary rigidity to navigate through tougher tissue planes and deposit the viscous product in a fanning pattern for optimal collagen stimulation.
-
Key Benefit: Precise deep placement and minimized risk of superficial nodules.
3. Calcium Hydroxylapatite (CaHA) (e.g., Radiesse®)
-
Product Type: Denser filler for deep volume and biostimulation.
-
Recommended Cannula: 25G-27G, 38-50mm length, blunt tip.
-
Why: The robust structure of a 25G cannula is ideal for the high viscosity of Radiesse. It allows for accurate placement on bone or deep tissue without bending, ensuring the product is deposited where it is most effective.
-
Key Benefit: Control with a dense product and avoidance of vascular structures.
4. Skin Boosters / Hydrators (e.g., Profhilo®, Jalupro®)
-
Product Type: Low or high molecular weight HA for skin hydration and quality.
-
Recommended Cannula: 30G, 25-40mm length, blunt tip.
-
Why: Skin boosters require superficial to mid-dermal micro-droplet deposition. A very thin, flexible cannula (30G) is perfect for creating multiple tiny tunnels with minimal trauma, ideal for sensitive areas like the neck and under-eyes.
-
Key Benefit: Minimal patient discomfort and seamless blending of product.
The cannula is no longer just a needle,it's an extension of the practitioner's skill.
Matching the gauge and length to the product's viscosity and the target tissue plane is a non-negotiable aspect of modern safe practice.
This approach significantly elevates the patient experience and the final outcome.
