The main aims of our present study were (1) to construct ageing trajectories for the female and male face between 7 and 17 years of age and (2) to propose a three-dimensional age progression (age -regression) system focused on real growth-related facial changes. However, most studies in this area fail to capture the essence of the face as a three-dimensional structure. Modelling of the development of facial morphology during childhood and adolescence is highly useful in forensic and biomedical practice.
