How it works
Everything begins with a consultation. The doctor who will carry out the treatment looks at the shape of your upper lip, how clear the curve is, how even the two sides are, and how the lip relates to the rest of your face. They will talk with you to understand what you want to change, ask about any allergies and any history of cold sores on the lips, and then explain which approach fits you and how much change is realistic for you in particular.
Before the injection, the lip area is usually cleaned and numbed with a topical anesthetic. Many fillers also contain a local anesthetic already mixed in to ease discomfort during the injection. You stay awake throughout. If you have ever had cold sores on your lips, the doctor may prescribe a preventive medication beforehand.
During the treatment, the doctor injects small amounts of filler into planned points along the border and curve of the upper lip, using either a needle or a blunt-tipped cannula depending on the case, to define and even out the lip line. They work a little at a time, shaping and checking both sides for balance. The appointment is usually short, around 30 to 60 minutes including the numbing time.
Once the shaping is done, the doctor checks the balance again, explains how to care for your lips, and arranges a follow-up if any adjustment is needed. One thing worth noting about hyaluronic-acid filler is that an enzyme (hyaluronidase) can be injected to dissolve it if the result is not what you wanted. The doctor will explain exactly what they plan to do at your appointment, including the limits of the approach, before you decide.
