Cosmetic injectables include botulinum toxin, which relaxes muscles, and dermal fillers, which add volume. Over the last 10 years, both have increased in popularity worldwide and, in many western countries, are the number one non-surgical treatment.
Fillers are either permanent or non-permanent, and can contain collagen, calcium hydroxylapatate, Poly-L-lactic acid, or hyaluronic acid – the most common non-permanent filler. Relatively lax regulation means some dermal fillers are imported and have no Medsafe, TGA or FDA approval, so check with your practitioner.
Serious complications can occur when fillers are inadvertently injected into arteries around the face. Blocked arteries may lead to skin necrosis and permanent scarring. If an eye’s retinal artery is blocked it can result in blindness. There have also been rare cases of stroke following filler injections.
Inadvertent injection into an artery can happen to any injector. It is crucial to promptly recognise an adverse event and treat it appropriately. Certaindermal filler adverse events are an emergency situation and it is vital the injector is aware of how to recognise and manage these.
Be sure the injector you choose is properly qualified and has a proper consultation and consent process.
