Treatment with Dermal Fillers is a non-surgical procedure. It is administered through injections by a trained medical professional. If you have tried Dermal Fillers before, you may have experienced discomfort. The level of discomfort varies from one person to another. It also depends on what product is being used and what area is being treated. For example, the lips can be particularly sensitive. Dermal Filler contains an anaesthetic called lidocaine, which has been shown to increase patient comfort. Also, the addition of the lidocaine simplifies treatment, as it means that a separate anaesthetic is not required.
