List of Treatments


Designed to address signs of ageing and replenish lost facial volume, these injectables typically contain hyaluronic acid, a natural protein found in our skin. They are used to restore volume and minimise the appearance of static wrinkles.

In addition to their volumising effect, some fillers also contain bio-stimulating properties that can stimulate collagen production to further promote the skin’s rejuvenation process, providing longer-term benefits beyond the volumising effect.

A range of FDA-approved fillers are available at Angeline Yong Dermatology which includes:

Hyaluronic Acid Fillers

As the areas on the skin are filled up, the skin “plumps up,” and wrinkles become less noticeable. The most commonly injected substance is hyaluronic acid gel, which is safe and poses minimal risks to the skin. Over time, the body slowly breaks down the hyaluronic acid, and hyaluronic acid fillers are fully reversible with the use of hyaluronidase.

  • Juvederm from Allergan
  • Restylane from Galderma
  • Belotero from Merz

Bio-Stimulatory Injectables

Biostimulators differ from hyaluronic acid in that they stimulate the body’s own collagen production, which leads to natural-looking and long-lasting results. These compounds are injected into the deeper layers of the skin such as the dermis to promote collagen formation. In this way, biostimulators aid to the skin’s ability to generate its own volume and structural proteins naturally.

  • Radiesse from Merz

Collagen Injectables

Also known as collagen filler, it is designed to mimic the natural structure of the body’s own collagen and effectively acts as ‘skin food’ by forming a connective matrix in the dermis and promoting a more youthful condition.

Unlike bio-stimulating filler, collagen filler contains a base of natural collagen. It is made of highly purified atelocollagen, which gradually integrates with and supports existing collagen in the skin, providing structure, firmness and volume over time.

  • Deusaderm from Sunmax Biotech

Each product line contains different formulations and densities to treat different areas. Typically, denser fillers are injected deeper into the skin, while lighter fillers are used for fine lines and areas such as lips and tear troughs. Certain hyaluronic acid fillers are also used for skin hydration purposes.

Other indications

  • Skin hydrating boosters are also used to improve the moisture-levels in your skin

Depending on patients’ skin goals, Dr Angeline Yong will assess the types of fillers used to achieve optimal results tailored specifically for each individual’s needs.


  • A topical numbing agent is applied
  • Filler is injected into the area requiring treatment either with a needle or cannula technique and this choice depends on factors such as the location, treatment indication and patient preference
  • The area may be gently massaged to spread the product (depending on the type of injectable used)
  • Number of injections/ products used is based on the extent of repair or enhancement desired

Some of the latest filler products contain lidocaine (an anaesthetic), making patients more comfortable during and after the procedure. Results are usually visible contemporaneously with most filler treatments and last on average 6 to 12 months, depending on the type of filler used and the area into which it is injected.
