Dermal fillers are injectable treatments used to restore volume, soften certain lines and enhance facial contours.

Most commonly used fillers contain hyaluronic acid, a substance naturally found in the skin that helps retain moisture and support tissue volume.

What can dermal fillers be used for?

Depending on the product and treatment area, fillers may be used to:

  • Restore lost facial volume
  • Add definition to the cheeks, chin or jawline
  • Enhance or balance the lips
  • Soften folds and deeper lines
  • Improve the appearance of under-eye hollows
  • Adjust certain facial proportions

How do dermal fillers work?

What can dermal fillers be used for?

The filler is injected beneath the skin at carefully selected depths and locations. Rather than changing the whole face, treatment can be targeted to specific areas where additional volume, structure or support is needed.

Results are usually visible immediately, although temporary swelling can affect the final appearance during the first few days.

How long do results last?

Dermal fillers are temporary. Longevity varies depending on the product used, the treatment area, individual metabolism and the amount injected.

Hyaluronic acid fillers may last from several months to well over a year in some areas.

Are dermal fillers suitable for everyone?

No. Suitability depends on your medical history, anatomy, skin condition and treatment goals.

Fillers can also cause complications, including bruising, swelling, infection and, rarely, vascular occlusion. For this reason, treatment should be performed by an appropriately trained practitioner who understands facial anatomy and can recognise and manage complications.
