Dermal Fillers

Dermal fillers are aesthetic gel-based treatment injected into the skin. They are specifically designed to reduce the appearance of wrinkles, contour the face and create volume – most popularly used for Lip enhancement. Some dermal fillers are also used to hydrate and revitalise your skin, such as HydraFiller . But how do dermal filler work?

How does it work?

Dermal fillers work by imitating a naturally occurring substance within your body – a sugar molecule that exists naturally in almost all living organisms. Its normal function is to bind water so it acts as a lubricant and shock absorber in movable parts of the body, such as joints. It is also important for the transport of nutrients and in regulating water balance in skin. By boosting your skin with this naturally occurring substance, dermal fillers revitalise and add volume to the area instantly. This diminishes the appearance of lines and wrinkles, and giving a natural softer look. The gel we use is very tissue-friendly and closely resembles that which exists in the body.

How long does it last?

One of the great advantages of dermal filler treatment is that the effects are long lasting but not permanent. Dermal filler products are biodegradable, which means they will naturally disappear in the body. The longevity of your filler can vary, depending on the brand, thickness and area treated. Duration also depends on many factors, such as the individual’s skin type, skin condition lifestyle and age.  To ensure an optimal and long lasting result, a top-up treatment is recommended 6-12 months after your initial treatment. Our experienced doctors and registered nurse injectors will guide you on the appropriate time for your follow-up appointment.

Does it hurt?

This will really depend on the individual. The injections themselves feel like a slight pinch, and you may experience slight pressure or a ‘stinging’ sensation as the product is being injected. Depending on the area, your cosmetic injector may apply numbing cream to the area to be treated. Some of the fillers already contain local anaesthetic which also makes the treatment more tolerable

Risks and Side effects

Dermal fillers are considered to be safe but side effects can occur. The most common problems include:

  • skin rash, itching, or pimple-like eruptions
  • redness, bruising, bleeding, or swelling
  • undesirable appearance, such as asymmetry, lumps, or overcorrection of wrinkles
  • skin damage that causes a wound, infection, or scarring
  • ability to feel the filler substance under the skin
  • blindness or other vision problems
  • death of skin cells due to loss of blood flow to the area
