Blunt Tip Microcannulas

Dermal Filler Injections: Sharp Tip vs. Blunt Tip

Many spas offer dermal filler injection services. Each and every one has their own way of doing things. While many still rely primarily on sharp tip dermal fillers, others are beginning to realize the many benefits of blunt tip treatment.

Despite the fact that blunt tip fillers are typically better than the alternative, many estheticians do not know about them. For this reason, they continue to offer only sharp tip services, never knowing that blunt tip treatment may be a better option for their clients.

What you need to Know

Blunt tips for dermal filler injections have just recently begun to grow in popularity. There are many reasons for this, including ease of use, cosmetic outcome, and of course, the satisfaction among patients in terms of final appearance and comfort.

As the name suggests, blunt tip microcannulas are a large contrast to sharp hypodermic needles that were used for many years.

Benefits of Blunt Tip Treatment

Since sharp tip dermal fillers have been commonly used for many years, it is only natural for some people to shy away from making a change. However, it is important to provide clients with an option. It is important to provide clients with the appropriate information, ensuring that they are fully aware of the fact that blunt tip treatment may have more to offer.

Using a blunt tip can improve the way the dermal filler is injected into the skin. Known as the microcannula, this is a small, flexible needle that uses a blunt tip to ensure a fast and efficient process. Here are some of the many benefits, when compared to sharp tip treatment:

  • Minimal discomfort and pain
  • Ability for patients to return to normal activities the same day, thanks to little downtime
  • Less risk of complication
  • Fewer injections required for intended results (due to flexibility)
  • Reduced bruising (due to blunt tip)
  • The ability to cover larger areas during one treatment
  • Decreased swelling

These benefits are exclusive to blunt tip fillers, as sharp tip injections can be painful while also requiring more rest following the procedure.

Recent Study

Using the Global Aesthetic Improvements Scale (GAIS) to judge results, a recent study was conducted to compare the effectiveness and effects of blunt tip and sharp tip treatments.

To ensure accurate results, 95 patients aged 30 to 76 were included in the study. While many differences were found, the Visual Analog Scale for pain assessment turned up the most important finding. It noted that pain during the injections was different with each type.

For blunt tip injections, the pain was described as a three on the scale, which is mild. On the contrary, this increased to a six, or moderate pain, for sharp tip injection. Additionally, bruising was more prominent on those who received treatment with a hypodermic needle.

Since fewer punctures are needed with the flexible microcannula, it is only natural for there to be less pain and bleeding. More importantly, the blunt tip on the microcannula gently pushes veins and capillaries out of the way instead of puncturing them as a needle would. The result: much less bruising.


Several key points can be taken away from the study, including but not limited to:

  • Blunt tip microcannula has simplified this type of treatment
  • Blunt tip treatment produces less bruising
  • There is less pain associated with blunt tip treatment
  • Blunt tip treatment leads to a faster recovery time


Blunt tip and sharp tip dermal filler injections are both common, however, the blunt tip variety is beginning to take over as it provides a number of high level advantages over the alternative.

As more aestheticians learn about the benefits of blunt tip treatment, especially when compared to sharp tip, they will begin to incorporate blunt tip microcannulas to ensure that their clients receive the best possible results.
