There are a number of wrinkle fillers available in Australia. The most commonly used consist of hyaluronic acid ( H/A ) which is a naturally occurring polysaccharide (sugar substance) that exists in our skin and other parts of the body, including joints and the vitreous humour of the eyes. It is the most important space-filling substance in the body. It holds water to keep our collagen hydrated and our skin fuller and more youthful.
Our skin holds approximately 50% of our total H/A and renews itself more than any other part of the body. This substance is by our fibroblast cells. With age, the production of H/A is reduced, which leads to thinner, less hydrated, skin and other tissues. This leads to wrinkle formation and volume loss.
Synthetic H/A made from microbial fermentation is identical to our own H/A and is readily accepted by our tissues without allergy or significant side-effects. There have rarely been any reported issues of this nature.
H/A can be injected into the skin or into deeper tissues, such as fat, or under muscles to give a fuller, plumper and more youthful and more volumized effect. Any swelling, redness or bruising is due to the needle effect rather than the product, itself. These are short-term minor nuisance effects and not a health risk.
The newer versions of H/A have additional local anaesthetic in them. This makes for a more comfortable procedure, without the necessity of administering a dental block. The whole procedure is therefore quicker and more comfortable. The results are immediate and can be assessed and/or modified in the same session, if required. Most parts of the face and other areas such as hands, necks and decolletage can be injected safely and effectively.
There are several brands and varieties of H/A available to suit different parts of the face and other areas. Your doctor will discuss the benefits of each type to suit your needs. Most H/As will last about 12 months but some will last even longer. Also, some areas of the face will retain H/A much longer than other areas of the face.
There are other non-H/A fillers available and some "permanent" fillers available. Some of these have more serious side-effects or problems not associated with H/As.
