Dermal fillers used in this practice are hyaluronic acid-based injectable treatments. They are used to restore volume, soften certain lines and folds, and improve contour in a way that is targeted and reversible if required.
The most useful starting point is not usually a single line or feature in isolation. It is assessing the face as a whole. Volume loss in the cheeks, changes around the mouth, under-eye hollowing, lip definition and jawline support can all relate to one another, so the plan should be based on overall facial balance rather than a piecemeal approach.
