A major change in the way anti-ageing ‘fillers’ are being administered means that the risk of bruising and swelling from facial injectables is becoming a thing of the past.
As members of the British Association of Cosmetic Nurses learned at their Second Annual Conference this week, the manufacturers of several leading dermal fillers are proposing cannulas instead of needles for certain treatments. The benefits are numerous – including an easier injecting process that involves far fewer entry points and therefore less tissue trauma for patients. The outcome is a perfect result with no evidence of recent treatment.
“The introduction of the cannula is truly a technical revolution for professional injectors using facial fillers,” remarked Emma Davies, Chair of the British Association of Cosmetic Nurses (BACN), who explained that by using a cannula, the injector can deliver product to a wide area of the face through a single perforation.
Cannulas are devices with elongated, fine flexible tubes. A needle is used to pierce the patient’s skin and is then replaced by a cannula which can be used to introduce tissue fillers to several sites – for example, the mid-face, cheeks and the naso-labial folds – without puncturing the skin again.
Cannulas are especially useful for particularly sensitive areas of the face, such as around the eyes, and the lips. Because the skin is pierced far less when using a cannula, dermal tissue is less disturbed, there is virtually no discomfort for the patient and discoloration and oedema rarely occur.
