Abstract

Ce procédé de traitement cosmétique comprend une étape de pulvérisation pour pulvérisation, en direction de la peau ou des cheveux, d'un agent atomisé obtenu par atomisation d'un agent médical contenant une substance active prédéterminée, et de l'eau fine non chargée ayant une taille de particule inférieure ou égale à 50 nanomètres. Par conséquent, l'eau fine pulvérisée pénètre dans la peau ou les cheveux pour contribuer à une rétention d'humidité soutenue et forme un trajet pour la perméation de la substance active afin de favoriser une telle perméation. Ainsi, la perméabilité de la substance active peut être augmentée de manière plus appropriée.
