Dermal fillers - Can 1 ml filler be used in needles and canulla in the same session?

Hello and thank you for your question. Every provider has their own techniques, so that might be your dermatologist's preference. In our practice, we typically perform facial balancing treatments in one session. This can involve multiple syringes incorporating both need and cannula techniques. Needles and cannulas are attached directly to the syringe without having to transfer product, ensuring sterility of the hyaluronic acid gel substance.

Using both a needle and a cannula in the same session with a 1 ml dermal filler is technically feasible, but it requires careful handling and expertise. Here’s an overview:

Needle vs. Cannula:
Needles are sharp and allow for precise placement of fillers in targeted areas, such as the nasolabial folds.
Cannulas are blunt-tipped and are often used for areas where a smoother delivery and less trauma are desired, such as the pyriform fossa.

Technical Considerations:
Switching between a needle and a cannula involves transferring the filler, which can be done by attaching the syringe to different delivery devices. However, this requires skill to ensure sterility and avoid product waste.
The decision to use both tools depends on the treatment plan and the injector’s preference and experience.

Practicality:
While it is practical to use both tools in a session, your dermatologist may have specific reasons for their recommendation, such as minimizing trauma or optimizing filler placement.

Discussing your goals and concerns with your dermatologist can help determine the best approach for your treatment.
