What Are Dermal Fillers in Singapore?
Dermal fillers are injectable gels used to restore volume, smooth lines, and reshape facial contours without surgery. The most widely used type in Singapore is hyaluronic acid (HA) filler, a gel derived from a biocompatible sugar molecule that attracts and retains water within the skin. Other filler types include calcium hydroxylapatite (CaHA) and poly-L-lactic acid (PLLA), each with different properties, indications, and durations.
Hyaluronic acid fillers are reversible — they can be dissolved using an enzyme called hyaluronidase if clinically indicated. This reversibility makes HA fillers a commonly considered option for patients who are new to injectables. The longevity of dermal fillers varies by product type, treatment area, and individual metabolism. As a general guide:
- Hyaluronic acid fillers: approximately 6 to 18 months, depending on the area and formulation
- Calcium hydroxylapatite fillers: approximately 12 to 18 months
- Poly-L-lactic acid (PLLA): results develop gradually over several weeks and may last up to 2 years
Areas with greater muscle movement — such as the lips — tend to metabolise filler more quickly than areas with less movement, such as the chin or temples. Dr Sam will advise on an appropriate treatment interval during your consultation.
