Filler Injections
Injectable fillers are substances which can be injected under the skin to “lift and fill in” facial lines and creases, temporarily restoring its youthful and plumped-up appearance.
Injectable fillers are primarily used to improve the appearance of the skin’s contours. They can help fill out deep facial wrinkles, creases and furrows, sunken cheeks, skin depressions and some types of scars. They can also be used to add a fuller, more sensuous look to the lips. These dermal injectable fillers are particularly helpful for the treatment of nasolabial folds (lines from the side of the nose to the mouth that accompany aging) and wrinkles or marionette’s lines on the chin. Some newer injectable fillers also add thickness to the skin filling in areas of fat loss resulting from the aging process or side effects of certain drugs.
Injectable fillers are classified as temporary or semi-permanent based on how long they remain within the skin before being cleared by the body. Temporary fillers generally last several months while semi-permanent fillers last more than 1 year.
- Hyaluronic Acid Fillers
- Polylactic Acid Fillers
Hyaluronic acid decreases in our skin as we age, resulting in a loss of volume and poor water retention. Hyaluronic acid based fillers result in localized swelling as a result of more water binding to this acid. The body then gradually and completely clears the hyaluronic acid over several months. These fillers last between 9 to 12 months.
With increasing age, there is a combination of fat and soft tissue volume depletion, loss of skin elasticity and loss of skeletal support resulting in wrinkle formation, facial sagging and hollowness of certain areas of the face. Global facial rejuvenation is when injectable fillers are used to rejuvenate the ageing face in its entirety to restore its youthful appearance. Polylactic acid filler injections are able to do this by treating facial creases and restoring volume loss at the same time. It stimulates collagen production and dermal thickness thereby smoothening out lines and wrinkles whilst restoring lost facial volume resulting in a fuller younger looking face.

It is important to understand that fillers stay in the skin temporarily and are not permanent. The body breaks down the injected substance over a time frame of weeks to months to years depending on the material injected. Other factors, which may affect the durability of the injected fillers, are the age, genetic background, lifestyle and injected site in an individual patient. As a result, a repeat procedure or in some cases a “top-up” may be required to restore the facial contours after some time.
With most injectable fillers, the results are seen immediately. However with the use of polylactic acid, the immediate volume effect disappears within 72 hours and the filling effect is gradual over weeks to months. Pre and post operative photographs will be taken which usually will demonstrate the changes.
The effects of temporary fillers usually last between 9 to 12 months depending on the type of filler used and the rate that the body clears the filler which varies between individuals. Semipermanent fillers last between 1 to 2 years.
The injection of fillers is very safe when performed by an experienced and qualified dermatologist. However individual patients differ in their responses to “foreign substances” and some outcomes may not be predictable. Patients may experience some short-term redness, minor swelling and occasionally a small bruise. The swelling and redness usually goes away within 3 days. More long-term risks common to all injectable fillers may consist of infection, lumpiness and nodule formation.
