What is a microcannula?

Dr Sam Ghazawy’s user-friendly guide to microcannulas (strictly speaking, microcannulae), and why he uses them in his non-invasive cosmetic treatments. 

As a former ophthalmic surgeon, my knowledge and experience inform how I now treat patients in my clinic. 

So, when it comes to fillers, I’m pleased that my know-how with the use of a microcannula enables me to deliver successful results for my clients.


Well, because a microcannula is more effective and generally a lot safer than just using a traditional series of needles.  That is, it does a better job at delivering the filler where it needs to go.  And, at the risk of offering you a “too much information”-type fact, it substantially reduces the serious complications that could happen if filler were accidentally injected into a blood vessel. 

Let me explain (warning: a little bit explicit):

When someone uses a needle, because they’re rigid, have a sharp tip and pierce through tissue, things could go wrong. A needle slices everything in its path as it travels to where it needs to go – and it will pierce through blood vessels en route to its destination within the face structures. This increases the risk that the tip of the needle will be located inside a blood vessel when filler is injected. 

On the one hand, it’s not common, but the risk is still there.  On the other hand, this scenario is a cosmetic practitioner’s number one nightmare.

Additionally, traditional filler treatments using needle techniques can lead to higher chances of bruising, swelling, bleeding, discomfort or pain.

In contrast, the microcannula is a different type of instrument altogether.

Things to know about microcannulae

      Microcannulae come in different sizes, shapes and types of material.  Their application will depend on the procedure, the desired outcome and how best to reduce any risks involved.

      EdenMed still uses needles, as they have a place in minimally-invasive facial treatments.  Often, I use them in combination with a microcannula.

      You must be aware that no treatment is risk-free and that fillers delivered through microcannulae carry with them the possibility of something going wrong. Please ensure that Doctor Sam answers all your questions to your satisfaction.

      Should an emergency situation arise, Doctor Sam will act in your best interests, and as quickly as possible, to maximise your safety.  This may include stopping your treatment, dissolving the filler, treating an allergic reaction or referring you to specialist colleagues.

In summary, my patients are often surprised at the level of comfort they experience, not only during treatment but also afterwards.  And of course, they’re incredibly pleased with the results. Any questions? Get in touch with us via this website, or call 07946 518 372.

How the microcannula works

Not only does it have a blunt tip, it moves differently. Through the opening of a small “port” in the skin, it lightly slides and glides through layers of tissue.  The microcannula then gently separates the layers and deposits the filler into superficial or deep tissues around various areas, such as:







      Tear-trough area

As you can probably imagine, microcannulae are particularly useful for sensitive and tender areas of the face.


Modern cosmetic science increasingly sees the microcannula as a superior method to inject fillers.  

However, like all tools, they’re only as effective and safe as the person who uses them.  

There’s no need to worry. Through my work as an eye surgeon, I have in-depth knowledge and expertise in microcannula techniques.  In fact, they’re my preferred method of delivering fillers.
