The ageing process often results in a loss of volume in the face as well as a reduction in skin elasticity. These changes mean that fine lines and wrinkles across the face can become more visible with time. This is where dermal fillers can help -by restoring volume and stimulating collagen for a firmer, more youthful appearance.

What are dermal fillers, and why are they used?

Dermal fillers are a synthetic form of hyaluronic acid. Hyaluronic acid is a glycosaminoglycan which occurs naturally in our skin and plays an important role in retaining moisture and volume. Its role is often compared to a  sponge holding lots of water in the skin. As we age, we lose our natural hyaluronic acid supplies and as a result, our skin becomes less hydrated, less plump and less firm. Dermal fillers can mimic the role of this naturally occurring hyaluronic acid, restoring volume and hydration.

At the Dr Fiona McCarthy clinic, only the Juvéderm Vycross by Allergan is used as, very simply, Dr Fiona feels it is the best quality filler on the market. In her opinion, the consistency of the product means the best results for her patients. This range also lasts longer than other products and also has local anaesthetic incorporated in it, ensuring comfort during the procedure.

Where are dermal fillers frequently used?

Dermal fillers are mainly used on the face to restore volume loss caused by ageing. The areas most commonly treated are:

  • Lips (to improve volume and shape),
  • Cheeks (to lift, revolumise and contour)
  • Nasolabial lines (the lines that run from the nose to the mouth),
  • Chin (to add more volume and structure)
  • Jawline (to add definition)
  • Temples ( to fill the hollows that arise with age)
  • Under eyes


Dr Fiona also performs a combination of these treatments as part of a non-surgical facelift, or “8-point lift”.

What should I expect from the experience?

The nature of the filler procedure means that patients may experience slight discomfort upon injection- however, the Juvéderm dermal fillers used at The Dr Fiona McCarthy Clinic incorporate anaesthetic, to reduce any potential discomfort that may be experienced. If preferred, local anaesthetic cream can also be applied to the skin beforehand to minimise discomfort further.

How long do results last?

The longevity of dermal fillers will depend on which type of filler product is used – the Juvéderm Vycross range Dr Fiona uses are known to last longer than many other types of fillers available today due to their unique composition. The effect achieved through these fillers can last from 9 to 18 months, and their longevity will depend on both the area they are used to treat, and the lifestyle factors of the patient – such as their exposure to the sun, the physical activities they undertake, and their existing skincare regimen.
