How it works
Everything starts with a consultation. Your doctor will ask what you hope to achieve, look at the lines of your face and the bone structure of your chin from the front and in profile, assess how your chin relates to your lips and nose, and ask about your health history, the medicines you take, and any allergies. This is also your time to spell out your expectations and ask questions, so the two of you can agree on a realistic plan.
Before injecting, your doctor usually applies a numbing cream to the chin to keep you comfortable; many fillers also come pre-mixed with a local anaesthetic. The treatment is done right in the procedure room, while you are awake, with no general anaesthesia.
Your doctor injects the filler at planned points across the chin, using a fine needle or a blunt-tipped tube called a cannula, placing it in small amounts and shaping gradually so both sides stay balanced. The whole thing usually takes about 15 to 30 minutes, depending on how much filler is used and how many points need treating.
Throughout, your doctor injects and watches your chin in profile to adjust as they go. One advantage of hyaluronic acid filler is that an enzyme called hyaluronidase can be injected to dissolve some of it if the result is not what you wanted - your doctor will talk this through with you.
