Blunt-tip microcannulas are a staple of aesthetic practices. Providers choose them by gauge, length and flexibility for each technique, so a well-stocked practice keeps a short, deliberate range rather than every size available.
Gauge and length
- Common gauges range from 18 G (larger) to 27 G (finer).
- Lengths commonly range from about 25 mm to 70 mm.
- Finer cannulas are more flexible; larger gauges are stiffer and move product differently.
- Your injectors decide which combinations they use for each area.
Entry needles
Each cannula needs an entry needle, usually one gauge larger than the cannula, to create the entry point. Many cannulas come packaged with a matched entry needle, which saves pulling them separately.
Quality checks
Look for a smooth tip and side port, clear depth markings, a secure hub and individually sterile packaging. Inconsistent tips or burrs are reasons to change supplier.
Common mistakes
- Stocking many combinations that are rarely used.
- Running out of matching entry needles.
- Choosing on price alone when tip quality varies.
Questions to ask your supplier
- Is the entry needle included?
- Are depth markings provided?
- Is each cannula individually sterile-packed?
- What's the box count and case price?
Disposal
Cannulas and entry needles are sharps. Dispose of them in a sharps container at the point of use.
Stocking tips
Standardize on the three or four combinations your injectors use most, and order by the box. Keep a separate par for each injector if preferences differ.
Frequently asked questions
Do microcannulas come with entry needles?
Many do, packaged with a matched entry needle. We'll confirm that on the quote.
What gauges should we stock?
That depends on your injectors' techniques. Most practices keep a small range between 22 G and 27 G, plus a couple of lengths.
Can we buy by the box?
Yes. Cannulas are sold by the box, and case pricing is available on larger orders.
