Fillers are biomedical products that are injected beneath the skin to restore volume and fullness. Fillers have become an essential non-surgical treatment for facial rejuvenation.


There are two main types of fillers: permanent fillers and temporary fillers. Permanent fillers are not biodegradable and stay in the body permanently. The long-term effects of permanent fillers are unpredictable. The removal of permanent fillers is highly complicated, and complete removal is often impossible. The majority of fillers used currently are temporary fillers that are biodegradable. Temporary fillers are gradually broken down and leave the body through the natural biological process. Temporary fillers are generally safe and easy to use, with a high degree of safety and satisfactory results.


There are different types of temporary fillers available:

  1. Hyaluronic Acid (HA) Fillers. Currently, HA fillers are the most popular filler around. A hyaluronic acid is a form of an organic molecule that exists naturally in the body. Its primary function is to retain water to keep cells and tissues hydrated. Fillers made from HA have been used for many years and have good safety records. There are different types of HA fillers, depending on the structure of the molecule. High molecular weight HA fillers contain thicker and stronger gel, ideal for injection into deeper structures to restore volume and provide tissue lifting. Low molecular weight HA fillers contain a thinner and softer gel that is more spreadable, ideal for superficial and delicate areas such as the lower eyelids and around the lips. Depending on the molecular weight, HA fillers can last from 6 months to 2 years. Examples of HA fillers are JuvedermÒ and RestylaneÒ
  2. Calcium Hydroxylapatite (CaHa)Fillers. This group of fillers contains heavier and larger molecules, and they can stimulate the production of collagen. They are suitable for restoring volume in deeper structures and contouring certain facial features such as the nose and chin. The fillers generally last 12-18 months. An example of CaHa fillers is RadiesseÒ.
  3. Fat Graft. Unlike other commercial fillers, a fat graft is from the patient’s own body. Fat can be used effectively as filler in various parts in the face to provide desirable aesthetic results. (Please refer to Fat Graft)


Injection of fillers can achieve several desired aesthetic effects:

  1. Restore volume and provide lifting. Fillers can restore lost volume, such as in sunken cheeks and temples. They also offer lifting effects to counter saggy skin, improve tear trough, deep nasolabial folds, and marionette lines at the mouth’s corners.
  2. Improve skin texture. Hyaluronic acid fillers absorb water and retain water in the skin. The result is the restoration of hydration in the skin, reduce fine wrinkles, and make the skin appear more plump and radiant.
  3. Sculpture facial features. Fillers can sculpt and augment facial features such as the nose, chin, cheekbones, lips and forehead.





  1. Inform the doctor of any pre-existing medical conditions and drug allergy. All medical conditions must be treated and stabilized before the procedure.
  2. Stop smoking at least one week before the procedure. Smoking may diminish the results of filler.
  3. Stop the following medications and supplements one week before the procedure:
    1. All supplements containing vitamin E, ginseng, ginkgo, garlic, fish oil, and other ingredients increase bleeding during the procedure. Other supplements, traditional medicine, and herbs, in which elements are unknown, have to stop as well.
    2. Medicine that increases bleeding during the procedure such as aspirin, NSAIDs, and warfarin. However, you may need to consult your physician who prescribed the medication before you stop them.





Duration of Procedure: 5 to 15 min

Anaesthesia: Usually not necessary. Most of the commercial fillers have anesthetic medication inside. Numb cream or cold compression are additional measures for patients who are sensitive to pain.

Procedure: The doctor uses a fine needle to inject the filler into the target area to achieve the aesthetic goals.

Downtime: No

The onset of Results: immediate

Duration of action: 6 months to 2 years, depending on the type of filers.
