The present invention relates to a process for preventing andor reducing the signs of ageing of the skin, in particular for remodelling the face andor limiting the age-related hollowing of the face, by applying to facial skin a composition containing, in a physiologically acceptable medium, at least one rice protein hydrolysate and at least one agent for increasing glycosaminoglycan synthesis. Further, a prediction mode determining section selects a prediction mode from the prediction set thus selected. In addition, the tools have access to the data. The trajectory of the beam is curved by the field produced by the second magnet.
