What is Hyaluronic Acid Dermal Filler?
Hyaluronic Acid (HA) is a natural complex sugar that stabilises the skin structure, aids in skin hydration, and contributes to the elastic properties of the skin that allow it to remain tight. HA is constantly being remade and metabolised within the body as part of the natural biological process. HA dermal fillers therefore must contain a small amount of modification to ensure they are not metabolised in the body within 24 hours. Injections of HA dermal filler into the skin can help to replenish its natural support structures damaged by aging. HA injectable gel dermal fillers, are commonly used to assist the appearance of facial wrinkles and hollows and are also used to enhance your natural facial features (For Example, lip augmentation).
Results
The length of time the filler with last is dependent on a number of factors including the type of filler, the area treated and the volume used. A patient’s natural metabolism is also a factor in degradation, and environmental factors such as sun exposure and smoking have also been shown to degrade hyaluronic acid at a faster rate. Results have been shown to last from 6 – 24 months.
Deciding on a practitioner
All aesthetic practitioners need to be a registered medical professionals to be able to perform cosmetic injectable treatments. That is Registered Nurses, dentists, or doctors working independantly with dermal fillers, botulinum toxin, or threads. It is important before booking your appointment that you visit the nursing council, medical council, or dental council websites and check they are authentic practitioners in New Zealand. It is a requirement that you are to have a consultation by a medical, dental or nurse practitioner before undergoing treatment. This can be done in person or via video call. Often the aesthetic practitioner may suggest something different to your initial expectation, so it is important to be given time to think this information over before deciding on treatment. You should never feel rushed or pressured in any way. CosmeticAID strongly encourages clients to find a practitioner they feel comfortable and most importantly safe with. This will be evident in how your practitioner consults you as well as how they conduct their business. You should feel comfortable to ask any questions throughout the consultation and your practitioner must discuss all the risks and side effects of dermal filler.
| Common | Rare or Very Rare |
|---|---|
| Bruising | Inflection – viral or bacterial |
| Bleeding | Vascular occlusion – Filler entering a blood vessel |
| Swelling – mild to moderate | Skin discolouration |
| Redness | Tissue death and scarring – following vascular occlusion. |
| Tenderness | Haematoma – collection of blood under the skin |
| Discomfort | Inflammatory hardened nodules |
| Itching | Permanent disfigurement |
| Lumps and bumps (of filler) | Ulceration of the skin |
| Stroke | |
| Anaphylaxis resulting in death. |
Risks and Side Effects
There is always a small but definite risk that injections with dermal fillers may injure facial vessels. In many cases this results in bruising and/or swelling which will settle in the days or weeks following treatment. However rarely the filler may enter a blood vessel and produce a blockage that may result in skin breakdown and scarring. If detected and managed early, tissue breakdown can be avoided. It is important to communicate with your practitioner about any concerns you have following treatment. For more detailed information on how to recognise a vascular occlusion, please see our vascular occlusion information sheet.
Very rarely (estimated at 0.001%) blindness has occurred from filler entering a vessel which is unlikely to be reversed. Also, there is a very rare risk of stroke from filler entering into a blood vessel. There are certain areas of the face that will carry a greater risk of blindness and should be performed by an experienced practitioner with extensive facial anatomy and injecting knowledge. These include the frown lines, nose, forehead, temples, tear troughs and nasolabial (nose to mouth) lines.
