Microcannulas vs. needles – Why choose microcannulas?

Le monde de la médecine esthétique est en constante évolution et son marché en forte progression. Plusieurs facteurs ont renforcé la demande de soins esthétiques notamment l’explosion des réseaux sociaux ou l’utilisation de logiciels de travail à distance tels que Zoom qui mettent les utilisateurs face à leur image face caméra toute la journée. Les réseaux sociaux comme Facebook, Instagram et Tik Tok, omniprésents chez toutes les générations, mettent en scène des beautés parfaites à l’aide de filtres et retouches. Les standards de beauté n’ont jamais évolué aussi rapidement, tout comme la demande des patients qui souhaitent s’y conformer.

This new type of demanding patient is looking for painless and non-invasive anti-ageing treatments with fast and natural results. This demand has led to a real revolution in injection tools and techniques. Currently, there are two schools of thought in the injection techniques of fillers: needle injections and microcannula injections. In this article we explain the difference between the two techniques and what are the recommended uses for quality care.


Traditional use of the needle vs. safe use of the microcannula

Traditionnellement, les produits de comblement de médecine esthétique sont injectés à l'aide d'aiguilles. En effet, la plupart des fillers sont encore vendus accompagnés d’aiguilles d’injection, comme si c’était implicitement la technique recommandée.

Toutefois, il y a plusieurs avantages à utiliser plutôt une micro-canule à embout émoussée comme les SoftFil® Classic et SoftFil® Precision pour l'injection de produits de comblement.

Thanks to their rounded tip, micro cannulas remain the best way to avoid passing through a vein or artery. The use of needles or hyaluron pen can cause significant unsightly bruising or swelling, or worse, intravascular injections. When a needle is used, its sharp point penetrates deep into the skin. This is quite traumatic for the skin and the injected area. The consequences of a needle injection can be disastrous and can lead to blindness, stroke or necrosis. Thanks to its blunt tip, the micro cannula cannot pierce the skin and is a gentle and atraumatic procedure for the patient. The rounded shape of the microcannula tends to spread veins or arteries as it passes through the tissue. In addition, the aesthetic physician is able to feel the resistance of the structures through which a microcannula passes, which enables him or her to judge when and how to apply pressure or manipulate the direction of the microcannula.

The insertion of the microcannula requires a pilot needle to form its entry point. A pilot needle has been invented and patented by SoftFil and is called SoftFil® EasyGuide. Elle permet en un instant de trouver le point d’entrée et de procéder à une injection facilitée et sans douleur.

Also, the significant length of the microcannula compared to the needle is a strong argument in favour of the microcannula. Its length allows it to reach more areas of the face and body and to inject with fewer entry points in the skin. The microcannula is then used to pass through the entry point to the areas under the skin. One of the main advantages of blunt-tipped micro cannulas is the ability to use the same entry point without having to injure the patient with another needle prick. This automatic reduction of the entry points considerably reduces the patient’s pain and thus satisfaction. Its length and flexibility means a smoother and continuous distribution of the filler in areas that are difficult to reach, such as the jaw. A much shorter and more rigid needle has to perforate the skin several times in order for the filler to be delivered over the entire treatment area, so the choice of microcannula is less traumatic and painful for the patient.


What types of microcannulas for which injectable areas?

In addition to their effectiveness, safety and relatively low levels of post-injection pain, there are several types of microcannulas adapted for each use and for each type of aesthetic injection. We recommend the SoftFil® Classic et SoftFil® Precision ranges of microcannulas for users who are demanding in terms of the quality of their injection and the safety of their patients.

  • Micro-canules 14G et 16G : visage, bras et la poitrine
  • Micro-canules 18G : contour du visage, creux des yeux, bajoue, joue
  • Micro-canules 22G : creux des larmes, bajoue et joue
  • Micro-canules 23G : menton, zone rétro-mandibulaire, joues, creux des yeux
  • Micro-canules 25G : menton, bajoue, creux des larmes, cernes, glabelle, nez, front, décolleté et les mains
  • Micro-canules 26G et 27G: lèvres, nez et contour des yeux
  • Micro-canules 30G : menton, rides d’expression et lèvres


As far as the length of the microcannulas is concerned, this will depend on the needs of aesthetic physicians but also on the depth of the injected area. For example, an injection at the level of the columella will only require a length of 13 while an injection of the lips will require a microcannula of 40. All the guides and tutorials for the appropriate choice of sizes are available on our platform for training in the use of microcannulas: SoftFil® Academy.


How to learn how to use a microcannula?

SoftFil® has understood for several years the importance of training in the world of aesthetic medicine. Learning is an integral part of the daily life of doctors who naturally wish to adapt their techniques to the latest developments. These injection techniques themselves take many years to master.

The SoftFil® Academy was created in order to satisfy a strong demand from healthcare professionals for training in cannula injection. The interest of the cannula for doctors and patients is no longer to be proven, but the training courses are very few in number and difficult to access. SoftFil® has therefore developed its own online training platform, accessible to all doctors at no cost. A webinar, called LIVE Masterclass, is broadcast every month with interventions from international experts and KOL. Tutorial videos are posted regularly to illustrate all the injection areas and different techniques for using SoftFil microcannulas. We also offer private trainings for doctors who wish to have a more personalised approach to practice live on patients with the expert doctor.

Several hundred international doctors connect every month to the events and online training courses offered by the SoftFil® Academy. Its ambition is also to meet doctors, especially at medical congresses as soon as the health situation allows it, for conferences, live injections and presentations by our experts.
