New dermal fillers are pain-free and almost bruise-free. The needles in these fillers are replaced by micro cannulas, which are flexible and smooth. This helps in cutting down the pain to a large extent. Many patients think twice before getting a filling because of their needle phobia. This new technology effectively counters this factor.
What is this new technology and how does it work?
Cannulas are thin and flexible with a smooth rounded tip. They are screwed onto the syringe instead of the needle. They provide an even gentle fill. Like any injection, the product needs to be expressed before it is injected. This removes air and also helps ensure faster and more uniform flow. The micro cannulas access a larger area through fewer entry points.
This is great news for patients afraid of getting pricked. The rounded tip works by pushing aside vessels and nerves instead of poking them, cutting down the pain. Most patients who have undergone this treatment have given positive feedback.
The new tool for dermal fillers increases the surface area that can be treated with each entry. Doctors who specialize in treatments of this kind admit that this process is slightly longer than traditional needle fillers, but diminished side effects and increased comfort are completely worth the delay.
The techniques for using cannula need to be learned. There are workshops that provide this training. These workshops help increase the practitioners’ exposure and expertize in the area of smooth tip cannulas as a replacement for needles. According to doctors, this new treatment is a leap in terms of improving patient experience, during and post treatment.
Why needles are no fun
Needles are not preferred by many people because of following reasons:
- They might have to be inserted repeatedly for re-positioning.
- They cause bruising as a side effect.
- Some patients are terrified by needles, especially those who have a low threshold for pain.
- Needles lacerate blood vessels and can cause bleeding.
Because of these adverse effects, many doctors are abandoning needles and opting for cannulas for filling treatments.
Common uses of cannula in filling procedures
These dermal fillers are highly effective in cheek volumization. They are also used over tear troughs, temples, eyebrow, platysmal bands, the nasal bridge, ear lobes, marionette lines, preauricular fossa and perioral lines.
