The three families

The appointment
  • A consultation determines the appropriate filler and the areas to treat.
  • The procedure takes 15–60 minutes depending on how many areas are treated.
  • Topical anaesthetic may be applied to minimise discomfort.

Results are typically visible immediately, except with poly-L-lactic acid, which works gradually. The procedure is minimally invasive with little downtime.

How long it lasts
  • Hyaluronic acid — 6 to 18 months.
  • Calcium hydroxylapatite — up to 2 years.
  • Poly-L-lactic acid — up to 2 years.
Where filler is placed
  • Cheeks — adds volume and lifts sagging skin, restoring youthful contour.
  • Nasolabial folds — fills the lines from nose to mouth corners.
  • Marionette lines — smooths the shadows running down from the mouth.
  • Lips — enhances volume, shape and definition; corrects asymmetry.
  • Under-eyes — reduces hollowing and dark circles; requires expert technique.
  • Jawline — sharpens contour and adds definition.
  • Chin — improves projection, symmetry and profile balance.
  • Temples — fills hollows caused by fat and bone loss with age.
  • Forehead — smooths contour and creates harmony with the rest of the face.
Is it reversible?

Yes — fillers made with hyaluronic acid are generally reversible. If you are unhappy with the result or a complication occurs, a healthcare professional can inject hyaluronidase to dissolve the filler quickly. This applies primarily to hyaluronic acid fillers, not to every type.

Aftercare
  • Avoid strenuous exercise, alcohol, sun and heat for 24 hours.
  • Do not use AHA, retinol or vitamin C therapy for 24 hours.
  • Sleep on your back for the first few nights.
  • Drink plenty of water to keep the skin hydrated.
  • Minor swelling or bruising is normal and subsides within days.
  • Contact us with any concern about infection or reaction.
