Dermal fillers are made from various kinds of natural or synthetic materials, and there are a variety of fillers available on the market, both permanent and non-permanent. Non-permanent fillers, such as hyaluronic acid, have emerged as the leading choice among practitioners and patients.
The compatibility of these products with the dermis means that no pre-treatment skin test is required. They can last between 6 and 12 months, but this differs from person to person, and from one area of the face to another.
