Australian and International studies have shown most side effects with Dermal Fillers are not serious and are temporary such as pain at time of treatment and swelling and bruising after treatment. In experienced hands any pain or bruising and swelling can be minimised. However whilst Dermal Fillers are a safe procedure when performed correctly, complications can occur, especially with inexperienced injectors or when the wrong product is used. Rare but serious complications have been reported with Dermal Fillers including allergic reactions, skin infection, local skin necrosis and even blindness from needle trauma to the eye or injecting filler into the retinal artery. It must be remembered that Dermal Filler injections are a medical treatment using a prescription product and should be performed in a medical clinic by medical staff. Dermal Fillers are not a simple beauty treatment and should not be performed in a salon, shop, spa, hotel, resort, or party setting. All medical procedures carry risks and assessment by a medical doctor is mandatory before Dermal Filler treatment to evaluate whether there are any contraindications to treatment. Dermal Fillers should not be used if a patient is pregnant, breast feeding, or under 18 years of age. Caution needs to be exercised if there is a history of allergy or autoimmune disease. The choice of Dermal Filler is very important. Synthetic Dermal Fillers, whilst they last longer, are associated with much higher rates of complications such as hard lumps (nodules) which may appear months to years after treatment. At the Cosmetic and Laser we only use temporary Dermal Fillers based on natural Hyaluronic acid, as they are safer with fewer complications and they can removed fairly easily if necessary. Even with natural Dermal Fillers the choice of which formulation is used is important, as using a thick product superficially can result in lumps and using a less concentrated product for deep injections will not last long. The safest and best results with Dermal Fillers are achieved when an experienced and qualified practitioner uses temporary fillers in a medical clinic under medical supervision.
