If you have any knowledge of advanced aesthetics, you would be well-versed in the fact that injections are part and parcel within the cosmetic and dermatologic industry.

Most beauty procedures are done this way, but many individuals may not know that there are two means to do this: cannulas and needles.

What is the Difference Between a Needle and a Cannula?

The needle that is used for injection has had its tip hollowed, but it does not technically create a hole. This is the way that the product that is injected is drawn through the needle.

On the other hand, the cannula is a thin tube, which is longer and has a larger diameter. It has a flared end at the other end, which is thin, and it is used to create a hole through which the injectable substance is inserted.

The difference in design between the two basically dictates the injection technique that any professional will have to use for the procedure. These two styles will be commonplace in aesthetic clinics, depending on the treatments offered.

Which Is Better?

There is not necessarily a "better" technique between the two as both have their strengths and limitations. For either process, a needle will be needed to create the initial puncture through the skin.

The reason one might use a cannula is to efficiently deliver the medical substance without risking damage to veins and arteries. On top of this, it can reduce the level of discomfort and bruising experienced by the recipient.

On the other hand, the needle is sharper and would be preferred for quick procedures that require precise locations for pricking. Though it may be shorter and less flexible than a cannula, it is the most often-used method.

Of course, one needs to consider the exact treatment when deciding which route to pursue.

Is One Better Over the Other for Specific Treatments?

Because needles can create trauma on the skin when too many punctures are within the same region, cannula injections are often preferred for procedures that require various points to be targeted. For example, the addition of filler throughout the body may be more gentle and cost-effective with just one cannula entry point.

On the other hand, needles are better for minor procedures like touch-ups and small enhancements. It is also suitable for delivering your medical substances deeper within the superficial musculoaponeurotic system.

Practitioners with knowledge in advanced aesthetics will understand which process is best depending on each case. Every injection, treatment, and process will not exactly be the same as various patients have different needs.

It is also generally a good idea to stick with the method that is better for patient experience and which one is more mastered by the professional that will administer the treatment.

Final Thoughts

Both methods of administration have their own strengths and weaknesses, which means there is no correct answer on which one is superior. It's just good to know the differences between the two to properly assess which is best per situation. This will also help you to get the procedures that you want without being stuck with something that is not what you were expecting.
